Flowering Trees & Shrubs of Early Spring

Outside my window the Blireiana flowering plum is covered with dark pink, double blossoms. It’s one of my favorite early spring blooming trees with a sweet fragrance strong enough to scent the garden. We look forward to the earliest flowers of the new season knowing that winter will soon be over. Spring officially begins on March 20th.

Old fashioned shrubs like flowering quince and forsythia figure prominently in many old gardens because they are tough plants able to survive neglect and still look beautiful.

Forsythia ‘Kolgold’

The bare stems of forsythia are completely covered with deep golden-yellow flowers in late winter and early spring and become the focal point of the landscape when in full bloom. The showy stems of this easy care shrub are great for cutting. Forsythias are native to eastern Asia but a chance discovery in Germany by a grower who specialized in breeding for the cut flower industry led to the especially vivid variety ‘Kolgold’ in the 1800’s. Forsythia has long been used in Chinese medicine. The flower petals contain powerful bacteria-fighting properties which make it an important dressing.

Flowering quince

Flowering quince is another old garden staple providing early color. They are easy to care for and nearly indestructible in almost any soil that is well drained and not overly fertile. Once established quince is a very drought tolerant plant and their spiny branches make them an excellent choice for hedges, screening or as a security barrier. There are red, pink, orange and white flowering varieties. The Toyo Nishiki cultivar even has pink, white and solid red flowers all on the same branch.

Clivia miniata

What would a shade garden be without a bright orange clivia? Every year I look forward to their huge flower clusters that emerge from between dark green, strappy leaves. Even in dark shade they will bloom and brighten the winter garden although they would do fine in morning sun. If you have a north facing window you can grow them as houseplants. Clivia are hardy to several degrees below freezing but mine, under an overhang, have survived temps of 23 degrees without damage. Clivia breeders have produced gold and peach colored flowers also but I still like the standard orange ones.

A beautiful vine that blooms in winter is hardenbergia ‘Happy

Hardenbergia ‘Happy Wanderer’

Wanderer’. In the pea family, this evergreen vine looks like a small wisteria when in bloom. Pinkish-purple flowers cascade in clusters on twining stems that reach 12-16 feet long. It requires little water once established and is hardy to about 23 degrees. If you have an older, tangled plant you can rejuvenate it with hard pruning in early spring after flowering. Never prune in late summer or fall because you will cut off the wood that is going to bloom the following winter.

The last plant I couldn’t live without is Fragrant Sarcococca. The tiny white flowers of this plant are easily overlooked but you can’t miss their scent. I have one near the front door that greets me with that vanilla fragrance every time I walk in or out. The flowers are followed by a bright red fruit. Sweet Box forms a natural espalier against a wall and if you have a problem spot in deep dry shade where other plants won’t grow give this plant a try. They are easy to grow, deer resistant and trouble free.

Winter Weather All-Stars

Between storms I’ve been scouting for flowering plants that really hold up to pounding rain. Sure pansies, primroses and cyclamen are pretty but they’re looking a bit beat up about now. I have been impressed with many flowering shrubs and trees that are happily blooming despite so much rainfall this winter.

As I write this during another series of storms, my weather station here in Bonny Doon has recorded 85.06 inches of the wet stuff this season with 39.76 inches of that having fallen so far in January alone. I have put out straight sided containers on several occasions to double check my gauge with an old fashion ruler. Yep, the weather station is accurate.

All this rain makes me have even more respect for the flowering plants that are holding up to the weather. These plants are my heroes and you might consider including them in your garden too.

Autumnalis flowering cherry

One of my favorite small ornamental trees, blooming several times a year, is the Autumnalis flowering cherry. It blooms in the spring, a little during the summer, again in the early fall and then another round of blossoms show up in December and January. I’m not sure how it got the name Autumnalis ‘cause it sure can’t read a calendar. I was afraid I would loose the winter show with so much pounding rain but the pale pink blossoms have come through just fine and and chickadees who land in it before going to the feeder remind me that spring will be here before I know it.

Cinnamon Snow helleborus

Also here in my own garden the hellebore flowers are holding up well. One of my favorites is called Cinnamon Snow but all of the varieties of this buttercup relative accept wind, rain, cold and less than perfect soil while getting by with only moderate watering in the shady summer garden. Deer aren’t attracted to them either.

Australian fuchsia

Recently, after seeing a Pink Australian Fuchsia blooming so profusely despite the rain, I decided to add a variegated variety called Correa ‘Wyn’s Wonder’ to my own garden. Although not related to hybrid fuchsias, the flowers are similar and their nectar will feed the Anna’s hummingbirds. They grow well in dry shade under oaks are deer resistant and drought tolerant.

A favorite of birds and indoor floral arrangers is the evergreen mahonia. Plant a mahonia if you want to attract winter hummingbirds. They are blooming now with bright yellow flower clusters that will last for months. Each flower will set a purple berry looking like a cluster of grapes. The edible berries make good jelly, too. There are 70 varieties of mahonia including our own native Oregon Grape which grows in the understory of Douglas fir forests. Mahonia aquifolium is resistant to summer drought, tolerates poor soil and doesn’t create a lot of leaf litter.

daphne odora

Other tough winter blooming plants include winter daphne, abutilon, witch hazel, edgeworthia, camellia and grevillea. Driving around I’m seeing that the Saucer Magnolia’s don’t mind the pounding rain either. Enjoy color in the garden regardless of what Mother Nature brings our way.

What’s Old is New Again in Garden Plants

Pittosporum tobira fragrant flowers

I remember walking with the main horticulturalist at Filoli Garden many years ago and hearing her extol the virtues of the established plantings that have survived drought and neglect with no pest problems for a very long time and are still growing beautifully in the garden. It’s not always the latest cultivars that have staying power. Some of the newer varieties are better but some are not as vigorous, some of those lovely variegated, striped or dark foliage plants revert over the years, some are prone to pests and diseases. Don’t overlook using been-around-for-ages workhorse plants in your garden.

Some of the survivors at Filoli Gardens over the years are California natives and others are just tough plants from other parts of the world. Take the common pittosporum you see in most every old garden. This plant makes a fine hedge, focal point or ground cover depending on the genus with a sweet fragrance in the spring while providing the bones or structure to your garden.

All of the various types of pittosporum are hardy in winter, grow in sun or shade and have low water needs. Pittosporum tobira flowers are scented like orange blossoms. Pittosporum eugenoides and tenuifolium – commonly grown as a hedge or small tree – have highly fragrant blossoms as does the ground cover ‘Wheeler’s Dwarf’.

Lithodora ‘Grace Ward’

On a recent trip to the Gig Harbor, Washington area, lithodora ‘Grace Ward’ caught my attention in many gardens. With those electric blue flowers covering this ground cover it’s quite the show stopper. Lithodora is used more extensively than creeping rosemary in the Pacific Northwest as it can survive temps down to 0 degree or less. Growing with only moderate to occasional irrigation give this plant a try in your own garden.

agapanthus.2048
Agapanthus africanus

Next plant on my bring-back-the-old-favorites list is the lowly agapanthus or Lily of the Nile.  Sure you see it at every fast food restaurant and hotel you pass but the reason is that it grows and blooms so reliably with little care. This is one plant where the new cultivars are proving to be just a tough as the standard agapanthus africanus.

agapathus_Storm_Cloud
Agapanthus ‘Storm Cloud’

Agapanthus ‘Storm Cloud’ produces luxurious green foliage that tinges purple-red in the winter months. In summer large umbels of very deep blue flowers rise above the foliage on tall blackish stems. This variety takes a couple years to establish but blooms reliably from then on.

Two smaller types of agapanthus are ‘Queen Anne’, a semi-dwarf variety and the dwarf ’Peter Pan’. Both are available with blue or white flowers. There is also a variegated dwarf called ‘Tinkerbell’ which grows well also. All agapanthus tolerate frost and neglect and require only moderate watering.

So in addition to all the ceanothus- a California native- that grow so reliably don’t overlook some of these other workhorses. There’s a reason these plants have been grown successfully for such a long time. Be sure you include these old favorites in your garden along with those new cultivars that you just have to try out.

Spring Garden Madness & the Lessons Learned

Everybody’s garden looks the best in the spring. Plants are full of new, healthy growth and the heat of summer has not yet descended. Early flowering plants are at there peak and those that wait until summer to flower so that their nectar will attract hummingbirds, butterflies and bees are patiently awaiting their time in the sun. It’s a glorious time in the garden.

With this in mind I recently strolled Filoli Garden in Woodside to see what they were doing to conserve water while maintaining all their flower power. I also toured 5 gardens in Palo Alto on the Gamble Garden tour and got lots of ideas for sustainable and beautiful gardens.

Filoli Garden is eye candy for any gardener. The estate grounds are maintained to perfection and it was interesting to see what changes they have in store for all those gorgeous, emerald green lawns. The roses, foxglove and peonies were in full bloom, the tulip pots now filled with colorful pansies. Several lawn areas had been reseeded while the large north lawn at the top overlooking the grounds had been allowed to go brown. This is what I learned they have planned to conserve water for the new lawn areas.

Filoli is testing turf varieties that might grow well with less water and mowing in the coastal microclimate of Woodside. They have sown or planted twelve species and blends to trial. Each block will have a corresponding sign telling about the variety. The types being trialed include No Mow Fescue Mix, carex pansa, June grass, U.C. Verde buffalo grass, Pacific hair grass and Molate red fescue. Agrostis pallens, blue grama grass and purple needle grass are also included in the trials.

Many of these varieties are among the lawn replacement recommendations from Scotts Valley and San Lorenzo Water Districts. Rethink you lawn this year like Filoli Gardens and get a rebate, too.

Next on my spring garden tour agenda were several private gardens showcased on the annual Gamble Garden tour in Palo Alto. Because it’s a walking tour I got as many ideas from the gardens featured as I did passing by the front yards of the other houses. This is the neighborhood where Steve Jobs used to live. I don’t know if his family still does but his orchard on the corner lot is thriving.

The theme of this year’s garden tour, Garden are for Living, came through loud and clear in each of the gardens. Many featured sustainable features such as a decomposed granite patio that also serves also as a patanque court, poured in place concrete pavers, corten steel raised bed and path edging and dry laid flagstone paths. Edibles were included in every garden- from a grape-covered pergola to a cleverly designed raised veggie bed complete with steel corners and banding and lighting for evening dinner harvesting.

low water combination- Olive, Iceberg rose and rosemary

While walking the neighborhood a low water use plant combination of ornamental olive trees underplanted with rosemary and Iceberg roses complemented one Mediterranean style home. Another garden nearby featured a rustic fence made from fallen tree branches. I must have taken a hundred pictures to remind me of all the great design ideas I saw that day. There is nothing like a spring garden tour to get the creative juices flowing.

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.

Straw bale veggie garden with Joe Ghio bearded iris

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.

Edible Plants for Birds, Bees and People

rain gauge Nov1With every rain forecast I hope for enough precipitation to give my garden a good soak. Last Monday I was not disappointed. I heard the pitter patter of rain on leaves and jumped up in the morning to check the rain gauge. To my delight the last storm dropped 1.67 inches of the wet stuff on my garden in Bonny Doon. The prior three October showers had barely totaled a tenth of an inch. Last year, the hills and meadows were already greening up with 3” of the wet stuff. After this much needed precipitation the deer are happy, the forest is happy, our gardens are happy, everybody is happy.

Some weather forecasters are predicting a drier than normal November for our area while a recent NOAA (National Oceanic and Atmospheric Administration) report predicted El Nino rains starting this November. I’m going with the folks at NOAA. A November 1st rain event qualifies them as the best forecasters so far.

I’m enjoying the vibrant colors of the fall garden. Everything is brighter after a rain. I’ll also be looking for some new plants with berries for the birds, more shrubs with fall and winter interest and a couple new grasses. With water conservation in mind here are some of the plants I’m considering. Some put on their best show at the end of the season.

feijoa_sellowiana_flowers
PIneapple guava edible flowers

I can’t get enough of delicious pineapple guava fruit thanks to my best friend, Karen. Her plant is loaded with fruit this year. Pineapple guava has been on my wish list for a while because of its versatility and this fall I’m going to plant one. Easy to grow Feijoa sellowiana needs only occasional watering. An established plant can survive without any supplemental water but If you want to enjoy more flowers and delicious fruit give them a little extra water especially during flowering and fruiting periods. Mulch the soil around the plants to protect the shallow roots and conserve moisture.

The early summer flowers are showy, contrast nicely with the gray green foliage and are completely edible. You can eat them right off the plant, toss them into a salad, add them to iced tea or make jelly. They have a fruity flavor and bees, butterflies and birds also appreciate them. The pineapple-flavored 2 inch oval fruit is produced three to four months after the flowers. It’s easy to cut the little fruits in half and scoop out the fleshy inside with a spoon.

Pineapple guava grow at a medium rate to about 10 to 15 feet tall and wide. You can easily train one as an espalier, hedge or small specimen tree. They do well in containers, too, so if you’re like a lot of people with limited space or time this is a good plant to grow. Did I mention they’re deer resistant? This is one unfussy plant.

toyon-berries
Toyon berries

Another plant that is definitely going to be planted in my landscape this fall is a California native. Each year when I see a toyon (Heteromeles arbutifolia) covered in red berries I vow to get one for myself. They have very low water needs even in the summer and make a good addition for the back of the garden. Irrigate them occasionally during spring and summer to promote fire resistance. Although they often take a few years to establish, their deep roots are good for soil erosion and slope stabilization.

Also known as the Christmas berry, no berry is more sought after when is season. Robins love them. Waxwings and purple finches also rip open the fruits to eat in great numbers. Unlike pyracantha berries birds do not get drunk on toyon berries. Bees and butterflies are attracted to the flowers.

Toyon is one of the classic shrubs of the California chaparral. Except for an extension into Baja, the shrub only occurs in California. Its resemblance to European holly and abundance in Southern California’s Holly Canyon were the origin of the name Hollywood. The name toyon was given by the Ohlone tribe and is the only California native plant that continues to be commonly known by a Native American name.

Toyon make good container specimens and the berries can be used in place of English holly for Christmas decorating.
