Cool Ideas for Back-to-School Gifts

With the first day of school fast approaching parents are busy getting colored pencils, highlighters and markers for the new school year. Students need backpacks, clothes and other supplies too. Teachers are hard at work also getting their classrooms ready in addition to lesson plans. If you are thinking of getting your teacher and classroom a little back-to-school gift here are some suggestions that will do double duty as teaching moments and a thank you.

tillandsia

Plants are the perfect choice for a small gift. One easy-to-care plant is the tillandsia or “air plant”. A small one can be placed in a small shell or attached to a piece of driftwood and if given some light near a window and sprayed or dunked in water each week they will flower and reproduce by growing offshoots or “pups”. Turn this gift into a teaching moment to share with the rest of the class by writing out an explanation of their interesting ways.

Tillandsia like their relatives, Spanish moss and pineapple, have tiny scales on their leaves called trichomes which serve as very efficient absorption systems to gather water. They are very tolerant of drought conditions and will grow with just a spritzing of water although I like to run mine under lukewarm water to mimic the showers they might get where they normally grow on tropical tree limbs. They prefer the light from a bright window but not direct sunlight and are among the easiest of indoor plants to grow and maintain.

Another plant that would make a nice addition to the classroom is the succulent.  Succulents are easy to grow. They are very forgiving plants given different watering and light conditions. I’ve seen small ones planted in recycled boxes, old tins and hand decorated or painted clay pots. Succulents have an interesting life history that can be shared with the class, too.

A quick check of Wikipedia, the free encyclopedia, provides this information. In botany, succulent plants are plants that have some parts that are more thickened and fleshy in order to retain water in arid climates or soil conditions. The word “succulent’ comes from the Latin word sucus, meaning juice or sap. Succulent plants may store water in leaves, stems or roots and have the ability to thrive on limited water sources, such as mist and dew, which makes them equipped to survive in an ecosystem which contains scarce water sources. They can survive on sea coasts and dry lakes, which are exposed to high levels of dissolved salts that are deadly to many other plant species. If they can survive there they will flourish in the classroom.

spathiphyllum

Another gift idea for the classroom is a small houseplant that can clean the air. The first list of air-filtering plants was compiled by NASA as part of a clean air study published in 1989 which researched ways to clean the air in space stations. As well as absorbing carbon dioxide and releasing oxygen, as all plants do, these plants also eliminated significant amounts of benzene, formaldehyde and trichloroethylene. Other studies added to the list of chemical pollutants and the best plants to remove them.

NASA researchers suggest that the most efficient air cleaning occurs with at least one plant per 100 square feet. Even the microorganisms in potting soil remove some toxins. Some of the easiest houseplants to grow are some of the best to have in the classroom. Just about all the potted palms are good. Also rubber plant, dracaena ‘Janet Craig’, philodendron, Boston fern, ficus, peace lily, Chinese evergreen, spider plant, snake plant, pathos, English ivy and phalaenopsis orchids are high on the list.

Other gift ideas that would do double duty outside the classroom in life lab would be a packet of quick maturing seeds such as lettuce, spinach or other greens. Sow the seeds thickly into nice prepared soil on the first possible school day and begin harvesting the baby greens ‘cut and come again’ style about six weeks later.

The outdoor garden boxes always need new plants to attract polinizers and 4” pots are readily available. Choose from California native plants such as salvia and yarrow. Common garden plants that attract bees and other insect pollinizers are rosemary, lavender, sweet alyssum, glorious daisy and coneflower.

A Walk on the Wildside: The Ongoing Saga of the Hillbilly Gardener

Many years ago I was invited by a Scotts Valley resident to visit their garden. This was no ordinary garden I was to learn during my visit and each spring I look forward to seeing what’s new at Doc Hencke’s garden. From his roots in Oklahoma and Texas he describes himself as the “Hillbilly Gardener” but with his extensive knowledge of trees, vines and just about anything that grows he is one of the most successful and enthusiastic horticulturists I know. I wore my walking shoes and we started talking about what changes he’s noted in his landscape the past few years of drought coupled with this winter’s rains.

First stop- the straw bale veggie garden. The soil in this part of the garden is blue hard sub soil so this above-ground method of cultivation has been a real success. Richard told me that when the bales were first put in place a couple years ago he watered them thoroughly to start the fermentation process. Using a meat thermometer he determined by the internal temperature when fermentation was complete. He then soaked the bales with liquid organic fertilizer and applied some blood meal to augment nitrogen. The straw bales are decomposing each year but he’s going to use them once more this season. His crop of kale, lettuces and chard looked robust and happy.

Nearby a bed of Joe Ghio hybrid bearded iris were in full bloom. “It’s been a great year for iris”, Richard said. Not so good for peach leaf curl. The rains this winter set the perfect stage for the fungus to proliferate. He joked that the birds get the peaches anyway.

Richard is redoing his pond this year. He’s tired of fighting the raccoons and algae. Steeper sides will deter the raccoons and deeper water will help to prevent algae growth. He was forced to remove a curly willow that shed leaves into the pond as their natural salicylic acid was poisoning the pond.

Last year a new succulent bed was planted along the back of the house and patio. His Sticks on Fire all died over the winter from the cold and rain but the aeonium ’Zwartkop’, echeveria ’Sunburst’, kangaroo paw and various sedums were filling in nicely.

Below the patio the golden Mexican marigold and blue Pride of Madeira were in full bloom along with a gorgeous stand of Weeping Leptospermum. “Magnificent this year, just look at this plant. Can you imagine what it’s going to look like in another 15 years?”, he said. Pointing out the visual boundaries he creates with flowering vines growing up into the trees, Richard observed that some are going better than others. Sound familiar in your own garden? Even this expert propagator is sometimes stymied by Mother Nature.

I love to hear Doc Hencke’s stories as he shows me around. Stopping at a China Doll houseplant that has now grown into a tree he tells me he thinks it’s one of the tallest specimens ever. His giant bird of paradise flower pod opened last week. I’d never seen their enormous blue, prehistoric-looking flowers before.

Richard’s new desert garden along the driveway is growing in nicely with the aloe plicatilis blooming for the first time. Also the yucca he and his brother dug up inTexas is finally blooming. “I’ve only waited 52 years for it”, he laughs.

There are so many stories that come with each and every plant in Richard’s collection. It’s always a walk on the wild side.

A Day at the San Francisco Flower & Garden Show

water feature in a display garden

I remember my first San Francisco Landscape Garden show as it used to be called. The year was 1989- not long after the event started as a fundraiser for San Francisco Friends of Recreation and Parks. My father and I loved it. All those orchids and bonsai and beautiful gardens. It was held at Fort Mason and my father, a retired Army colonel, was quite familiar with the location. I was new to garden shows and was yet to discover that the display gardens are part theatre – part landscape design. ‘Who would plant a shrub that grows to 6 feet tall in front of that little bitty flowering perennial?”, I said to Dad. Well, I’ve been to a lot of garden shows since including the Northwest Flower and Garden show in Seattle and the San Francisco Flower & Garden Show when it was held at the Cow Palace and now, in it’s 30th year, at the San Mateo Event Center.

Fellow landscape designers at the show

So this year I know what to expect. Or I think I do but there are always surprises. I’m with a couple fellow landscape designers and we have a keen eye for new plants in interesting combinations and design solutions for upcoming landscapes. In addition to the show gardens there are also hundreds of vendors selling all sorts of wonderful garden related items and vendors selling every type of plant you could possibly want. So much fun. Here are just some of the highlights if you weren’t able to attend this year yourself.

The display gardens offer inspiration from lawn replacement ideas to sustainable building methods to exciting new plant introductions. For five days each March, people from around the world are brought together to educate, encourage and inspire garden enthusiast of all ages and all levels of knowledge and experience. This year was no exception although I wish there had been more display gardens like in the “good old days” of the garden show.

Who doesn’t enjoy sitting next to an impressive water feature? This year there were several incorporated in designs that also included low water use plants. A pondless waterfall can attract birds, butterflies and other pollinators to your garden. The soothing sound of the water can also mask street noise. One garden featured a Japanese bamboo deer scare or Shishi Odoshi. Perfect for a small space the bamboo spout fills with water and rocks forward to empty, then rocks back to create a gentle clacking sound.

Another impressive display garden featured succulents of every type and shape. Grouped by color and shape, large swaths of these modern succulents_basalt_column.1600looking plants created a living tapestry around columnar basalt landscape rocks. Other notable features of this garden were the brightly painted stucco walls enclosing the space and stucco-over-building-block retaining walls painted bright blue, red and terra cotta.

I probably got the most practical ideas from the garden created by the Association of Professional Landscape Designers than any other garden. Theirs demonstrated ways to re-imagine your garden without a lawn.There were cozy sitting areas. plants that screen out the street or next door neighbor, a vertical edible garden, lawn alternatives like Kurapia and vibrant planters filled with low water use plants. The whole garden was engaging and useful. I also saw a great idea for wall lighting that used a rusted metal screen in front of the light creating an interesting pattern. You had to be there to appreciate it’s unique design.

callistemon_Little_John.1600
callistemon ‘Little John’

For me and my colleagues the plants and garden art both featured in the gardens and for sale are what keeps us at the show for a long time. There are so many new plant introductions to evaluate for future designs. From new and improved selections of old favorites such as variegated lavender ‘Meerlo’, a soft mahonia ground cover, abelia ‘Miss Lemon’ to nandina ‘Lemon Lime’ and callistemon ‘Slim Jim’ there is a perfect plant for every garden.

Think about what you want to do in your front or back yard this year to save water and maintenance and enhance the beauty of your space.

How the Angel of Grief turned into a Cactus Garden

Angel of Grief
Angel of Grief

A friend of mine who attended Stanford University told me that the next time I was on the campus I should check out the famous Angel of Grief marble statue. Tucked in the trees behind the mausoleum that houses the remains of Leland Stanford, his wife and son, this statue was commissioned by Jane Stanford in honor of her deceased brother. It’s a duplicate of several others that are in places like Costa Rica, Canada, Luxembourg and Cuba and is actually the second on this site after the original was destroyed in the 1906 earthquake.

cactus_garden_path.1280It is indeed moving to stand in front of this massive white marble statue. Nearby is a cactus garden that is equally impressive to this horticulturalist. Alive with hummingbirds and songbirds, the flowers hummed with activity. In these days of designing drought tolerant gardens I’m always on the lookout for tough plants that combine well making a garden a delight to stroll and enjoy. I came away with lots of ideas. Here are some succulents that would work well in a drought tolerant garden in our climate.

senecio_mandraliscae.1280
senecio mandraliscae

On a hot day, the color blue makes everything feel cooler. Plants with blue foliage or flowers can serve to calm a riot of color, connect different color schemes and make a space seem larger. One such succulent that serves this purpose well is called Blue Chalksticks or senecio mandraliscae. As a ground cover this beauty spreads 2-3 ft wide but only 12-18” tall. It’s very drought tolerant in full sun or light shade but will also tolerate regular irrigation and is hardy down to 20 degrees. The blue-gray foliage really stands out when paired with burgundy or pink.

Another favorite succulent that I like to use in drought tolerant landscapes is the Ghost plant which is a much easier name to remember than graptopetalum paraguayense. The colors of their 3-6” wide rosettes are what really catch your eye. Ranging from lavender blue to light pink and pale blue on the same plant, this colorful succulent will spread wide but only about 1 foot tall. It’s very hardy to winter lows of 20-25 degrees and will even rebound from being frozen if temps drop below that.

calandrinia.1280
calandrinia

The Stanford cactus garden has milder winters than us so not all the plants there handle our cold and potential rainy winter weather. But another plant that does great in our climate is calandrinia grandiflora. Brilliant purple, poppy-like flowers rise out of a rosette of succulent gray-green leaves to make a colorful show from spring to fall. Beside being so showy- especially in a large group- this plants needs only very occasional water and is hardy down to 15-20 degrees. It’s super easy to grow and spreads quickly suppressing all weeds as it grows. Maybe that parking strip out front or bare hillside would look great planted with some calandrinia.

euphorbia_lambii.1280

As I strolled through the many winding pathways in this cactus and succulent garden I was amazed when I came across a tree euphorbia taller than I. It really does look like something straight out of a Dr. Suess book. It would need a bit of protection here when temperatures drop below 25 degrees but if you like unusual plants this is the one you’ve got to have. Between the long yellowish-green leaves and the bunches of greenish-yellow flowers-really bracts- it’s a show stopper.

barrel_cactus.1280

Besides the massive barrel cactus in the Stanford cactus garden, there are many, many varieties of aloe, agave, hens and chicks and yucca to name just a few. I was reminded by the huge Joshua trees of my years living in the Antelope Valley. This garden was originally planted around 1880 and many of the original historical plants are still there. Volunteer restoration work began in 1997 and is ongoing. With approximately 500 cacti and succulents it’s worth checking out if you’re in the area.

Blooming Gifts for Gardeners

Echeveria_LaceIt’s as fun for me to give a little something during the holidays to those I care about as it is to receive a present. I admit I look forward to what might be under the tree but half the fun of the holidays is putting together an inexpensive gift that is just right for each person on my list. With so many gardeners on that list, the choices are endless. Here are some ideas that you might find just right for those you love.

Succulents are easy to grow. They are very forgiving plants with variations in watering and light conditions. Seems I’m always coming across someone who has a story about how long they have had a particular specimen and where it came from. “You see that hens and chicks over there?”, they say. “Well my aunt gave me a little slip way back in… and it blooms every year.”echeverria_ruffled

I’m particularly drawn to the many frilly and ruffled echeveria that are available now. There are 180 different species of this succulent and hundreds of hybrids to choose from. Many of them are blooming at this time of year making them a showy gift that’s sure to get you a lot of thanks. With names like Afterglow, Easter Bonnet, Red Edge, Coral Glow, Perle Von Nurnberg, Morning Light, Blue Surprise or Fire and Ice you can pretty much pick the shade of scarlet, tangerine, purple, opalescent blue or nearly black, often with a combination of colors.

These rosette shaped succulents are native to Mexico. The brilliant colors of the leaves never fade and the waxy flowers last a very long time. They make ideal potted plants and are easy to propagate. The perfect gift in my book.

Another simple, inexpensive gift for the gardener on your list is the tillandsia. Sometimes called air plants, these relatives of Spanish moss and pineapple have tiny scales on their leaves called trichomes which serve as very efficient absorption systems to gather water. They are very tolerant of drought conditions and will grow with just an occasional spritzing of water although I like to run mine under lukewarm water to mimic the showers they might get where they normally grow in tropical tree limbs.

Tillandsia prefer the light frtillandsiaom a bright window but not direct sunlight and are among the easiest of indoor plants to grow and maintain. Wire one on a branch or piece of driftwood or place in a shell where they will live happily for years growing pups at the base that replace the mother plant.hyacinth_jars.1600

It’s not too late to start a couple of hyacinth bulbs in the refrigerator to give as gifts. Part of the fun is watching the bulbs put out roots well before the fragrant blooms. Choose a hyacinth jar or other narrow necked jar that will support the bulb just above the water and keep in the frig until roots start to fill the jar. Take the bulb out of the dark and give it a bit more light each day for a week until acclimated to bright light. The house will fill with the sweet scent of spring even though it may only be January.

They say that we often give a gift that we ourselves would like to receive. Simple is sometimes the best but they all say “love”.

Gardening Projects and Ideas for a Rainy Day

As I looked out the window at the rain coming down I thought of all the things I should be doing in the garden. “Where does the time go”, I thought to myself. “Why did you frolic in all that sunshine last month instead of transplanting and moving plants to better spots”?  I could tell from the conversation going on in my head that I needed some inspiration so off I went to visit a local garden store. I knew I was in trouble as I explored and wanted to buy nearly every cool plant I saw. Here are some of the plants that really caught my eye.

tillandsia_on_apple_branchLast month for my birthday a friend gave me a collection of tillandsia attached to an gnarled, mossy apple branch that had fallen from a tree in her garden. There are many kinds of these bromeliads or air plants as they are sometimes called and they can be displayed in lots of ways. At the garden store, I saw miniature hanging terrariums that looked awesome with several tiny tillandsia specimens, glossy pebbles and moss bits arranged inside. The humidity inside the glass as well as the bright light from a window is just what they like.

Other tillandsia were mounted on bark, some on driftwood, some in table top terrariums and some displayed in beautiful baskets. Tillandsia, like their relatives, Spanish moss and pineapple, have tiny scales on their leaves called trichomes which serve as very efficient absorption systems to gather water. They are very tolerant of drought conditions and will grow with just a spritzing of water although I like to run mine under lukewarm water to mimic the showers they might get where they normally grow in tropical tree limbs. They prefer the light from bright window but not direct sunlight and are among the easiest of indoor plants to grow and maintain.

I’m always on the lookout for ideas for landscape plants that might be perfect in an edgeworthia_chrysanthaupcoming design. Often what is needed to complement a house or view from a window is a plant with interesting foliage color or  branching pattern and bark in the dormant season. Showy, fragrant flowers make a welcome addition to the front entry at any time of year but I found one new to me and it’s blooming now.

Tucked among other plants with soft yellow and green foliage I saw my first Edgeworthia or Chinese Paper Bush. Also called yellow daphne, this daphne relative is grown mainly for its flowers. Tubular, bright yellow flower clusters fade to creamy white. The showy display is memorable. They definitely possess that weird appeal that collectors love. In China this plant is used to make paper and medicine.

Edgeworthia chyrsantha are hardy to 10 degrees and prefer half day sun or afternoon shade during the hot summer sun. They grow to about 6 feet tall and a bit wider. The tropical looking foliage is attractive during the summer but it’s the overwhelmingly fragrant display of pendent, golden yellow flowers that will make you want to grow this shrub in your garden. I’m looking forward to planting it next to a fragrant daphne.

pittosporum_tenuifolium_Irene_PattersonAnother plant that caught my eye was an Irene Patterson pittosporum tenuifolium. With speckled frosty green leaves this shrub will really light up a dark area. It can take full sun but it’s the shady areas I have in mind. Hardy to 15-20 degrees it will survive our winters and is adaptable to most soils. I think it would look great paired with the variegated huge green and white leaves of ligularia argentea.

I was also inspired to plant up my own succulent garden after seeing the display planted in recycled wooden boxes, old tins, antique cheese boxes and weathered boots. Whatever you have on hand with a drainage hole will look   succulent_garden2great with a succulent or two planted inside. Succulents in containers can be moved out of winter frost and rain which increases the variety that can survive in our area. I have a vintage Swift’s Silverleaf pure lard tin that’s just waiting to provide a home for some new succulents.  I’m looking forward to going back to the garden store to choose just the right specimens for his special container.

It’s fun to have some gardening projects that I can do indoors. There’s lots of time to plant those new landscape plants that caught my eye on a rainy day.
