Fall Blooming Perennials

Every garden changes over time.  Gardening is a process, a constant experiment so don't get discouraged when things don't go exactly as planned. For example, a cool spring may cause some things to bloom later while a warm, dry winter speeds up plant and flower development. Maybe that pink flowering tree now conflicts with the red blooms nearby. Whether it's caused by climate change or just the weather, take comfort that your garden can grow more beautiful each year with a little tinkering now and then.

At this time of year look to the following plants combined with ornamental grasses coming into bloom to carry your garden until autumn color from trees and shrubs kicks in. Go for dramatic extravagance with color combinations than inspire.

Russian sage.  Tall, airy, spike-like clusters , create a lavender-blue cloud of color above the finely textured gray leaves. This perennial has a long blooming season and the cool color of the flowers is stunning in the fall garden. There are several varieties available with different shades of soft blue to violet blue flowers. Most grow 3-4 ft tall. Little Spire Russian sage is a shorter, upright selection that doesn't flop over in the landscape. It adds a sense of lightness to the garden. You'll love the cool color on a hot day.

Aster x frikartii 'Moench'.  The lavender-blue flowers on this perennial can get 3" across and cover the plant with blooms from early summer to fall, even longer in mild winter areas if spent flowers are removed. They attract butterflies and make a good cut flower. This reliable, drought tolerant plant thrives in full sun, grows 2- 3 ft tall and is mildew resistant.

Agastache which is also called hyssop attracts hummingbirds, butterflies and bees to your garden It's also deer resistant. Aromatic foliage on Blue Fortune smells like peppermint-lemon when brushed or crushed. The flowers on Electra are vivid orange. Then there's licorice mint hyssop, orange hummingbird mint hyssop, anise hyssop and a whole slew of hybrids of every color in the rainbow- lavender, pink, apricot, orange, purplish, coral, powder blue, tangerine, red – you name it. Agastache is easy to grow in full sun or partial shade and is drought tolerant. Just be sure to provide excellent drainage.

Salvia-  the workhorses of the garden. Their long blooming season makes them right at home in the fall garden. There are some 900 species of salvias.  They are the largest genus in the mint family. Choose from many new cultivars like Dancing Dolls with rose and cream colored flowers. Another good choice is a Ca. native hybrid called Starlight that blooms with long white flower wands that really stand out at twilight.
There are lots of Salvia greggii varieties available such as Pink Frills, Golden Girl and Neon Dancer which has vivid rose and red flowers.  Salvias are drought tolerant and deer resistant (really). Although they tolerate some shade they looks best when planted in full sun. To encourage repeat bloom trim off spent flowers stalks when they start to look rangy. They will rebloom for months.

Another common plant from this huge family is the Mexican bush sage.  So showy that people mistake them for huge lavender plants. They are vigorous and upright growing to 3-4 feet tall and as wide.  Velvety purple and white flowers cloak foot-long stems. Salvia Santa Barbara is a compact selection that grows 2-3 ft high and spreads 5 ft wide. They stop blooming only when frost hits them.  To limit plant size and renew flowering stems, cut back close to the ground before spring growth begins.  You can't go wrong with these plants if you have a large space to fill.  Hummingbirds love them, too.

Perennials should be planted in multiples, not only for beauty's sake but also for lower maintenance. Let your trees and shrubs lend structure and year round interest with an explosion of perennial color that gets all the attention. Just don't hesitate to change what needs adjustment or transplanting if needed to a better location.

Good Shrubs for Erosion Control in the Santa Cruz Mtns

You know fall is just around the corner when you hear thunder. Seems like summer just started but now plants like lilac, rhododendron and dogwood have already set flower buds for next year. We don't know exactly what winter will bring. Will we receive lots of rain or a meager amount?

The latest from the Climate Prediction Center for the San Francisco Bay Area 2012-13 rainy season is that a mild El Nino event may be setting up. There has been a  weakening of the positive sea surface temperature in the Pacific. El Nino has been known to come with plenty of rain for our area. We are still in a wait and watch mode.

Long range outlooks for the fall from the CPC run from equal chances for above or below normal rainfall to a slight tendency toward below normal. For the November through January period the probabilities start to shift and a slight chance of above normal rainfall creeps up along the coast from the south.  By the time we get to the December through February period, the outlook is for above normal precipitation for the whole state with significant above normal chances for the Bay Area.

This is not a forecast but an outlook for the probabilities of above or below normal precipitation. If we do get heavy rains in January or February you should be prepared. Do you have a slope that might have an erosion problem?  Now is the time to start planning and planting. The nights are cooler, the days shorter, the soil still warm. Everything that a new plant needs to get a good start.

What plants are good for controlling erosion in our area? When choosing plants to cover a bank for erosion control, assess the conditions of the area you want to plant.  Is it in the sun or shade?  Is it a naturally moist area or dry?  Do you intend to water it or go with our natural cycle of wet in the winter and dry in the summer? Matching the plant to the site conditions will ensure success.

When designing a plant layout I consider whether I want a sweep of the same plant or a tapestry effect with a variety of plants.  Using more than one type of plant allows me to work with contrasting foliage adding pattern to my composition.  To create a stunning combination choose 5 or 6 styles and repeat them in small drifts to carry the eye through the composition. Add grasses for linear texture.

If the area you need to stabilize is large and mostly shade, consider Ribes viburnifolium aka Evergreen Currant which grows 3-6 ft tall spreading to 12 ft wide. It needs no irrigation when established. Another plant that tolerates shade and needs no irrigation after 3 years is Mahonia repens aka Creeping Mahonia. It grows 1 ft tall by 3 feet wide spreading by underground stems that stabilize the soil.

Symphoricarpos aka Common Snowberry or Creeping Snowberry can hold the soil on steep banks. They tolerate poor soil, lower light and general neglect. Philadelphus lewisii aka Wild Mock Orange tolerates some aridity and partial shade. This beautiful, fountain shaped, fragrant flowering shrub grows about 8 ft tall by 8 ft wide and is not fussy about soil.

A bank in the sun would contain a different plant palette. Some of my favorite plants to control erosion in this situation include Ceanothus in all its forms. Groundcover types like Centennial, Anchor Bay and Maritimus are not attractive to deer like the larger leaved varieties. Rockrose such as Cistus purpureus also provide large-scale cover for expansive sunny areas.  Their dense strong root systems helps prevent soil erosion. Choose from white, pink or magenta flowers on plants varying from 1-5 ft. high depending on which variety you choose. This Mediterranean native is fast growing, drought tolerant and deer resistant.

Smaller plants for color that control erosion are lavender, California buckwheat, salvia leucophylla, California fuchsia, deer grass, needle grass, mimulus, yarrow, Pacific Coast iris, bush poppy, penstemon and artemisia.

These suggestions are just a few of the plants that control erosion. Every area is different and every situation unique. Email me if you would like help with your area.
 

Poisonous Natives / Deer Resistant Natives

July already. Plants are growing like there's no tomorrow. The hummingbirds are my constant companions in the garden and the resident deer population comes by daily. There are two spotted fawns that now accompany their mother along with a couple of her sisters. Life is good.

I see them sampling plants what the older deer are trying. There are native plants that are poisonous for us but only some of them are avoided by deer. It got me thinking. How do deer eat poisonous plants without apparent ill affect?  

Deer are browsers. They thrive on a mixed diet. You've seen them eat a few roses then saunter over to the abutilon and then on to the daylily flowers. Deer will eat almost anything, even plants with a strong scent like catmint, lavender,  or thyme when they are hungry or need water. They can even eat a few bites of various toxic plants.

According to Tom Hanley,  a wildlife biologist with the Forest Service Pacific Northwest Research Station, "There seems to be threshold levels for the toxicity of different plants, and as long as deer eat below that threshold, they're okay."  Plant toxicity varies with the time of year also and flowers may be less toxic than leaves or roots. They just mix it up.

That explains the eating habits of deer but what about us?

Many of us are including native plants in our landscapes to attract wildlife and save water and resources. Here are some common native plants that you should be aware of if you have small children.  This list comes from
Borstein, Foss and O'Brian- California Native plants for the Garden.

Coffeeberry- leaves, berries and bark
California buckeye- all parts  (poisonous to bees also)
Western azalea- all parts
Elderberry- all parts except ripe berries and fruit
Solanum-all parts
Snowberry-berries
California buttercup- juice of the plant
Berberis- roots and leaves
Prunus ( cherry )- seeds
California poppy- all parts
Lupine (annual)- seeds, fresh leaves and stems.

Mostly though, native plants make great additions to the garden. They tend to be well behaved and are rarely invasive. Birds and butterflies rely on them for food, shelter and nesting. And best of all they are beautiful.

When I'm designing with native plants I find the following plants are fairly safe around deer. They are not perfectly safe at all times of the year but they are usually avoided.

Artemisia also called Ca. sagebrush
Asarum – Wild ginger
Baccharis – Dwf coyote brush
Ceanothus  'Julia Phelps'
Eriogonum – Ca. buckwheat
Douglas iris
Mimulus auritanicus – Sticky monkey flower
Monardella – Coyote mint
Ribes speciosum – Fuchsia-flowering gooseberry
Salvia

Enjoy your garden. Let the deer browse elsewhere and be aware of plants that may be toxic to children.

 

Hidden Gardens of Bonny Doon

Enter the Hidden Gardens of Bonny Doon with me as I preview several gardens that will be featured on the tour this coming weekend.  While some of our gardens have a few areas with a "wow factor" , the gardens I was privileged to visit have this element at every turn. I was amazed, impressed and truly honored to spend time in each of them.

First stop was a garden that took my breath away. Looking past the lush lawn, the view takes in all of Monterey Bay. It wasn't always this way, the owner explained. When she moved to the property in 1981, she didn't even know there was an ocean view. It was only after some judicious pruning that this stunning view was revealed.

We  ambled through the many paths that took us up close and personal with perennial beds overflowing with blooming iris, spirea, weigela, succulents, hardy geraniums, coprosma and coleonema to name just a few.

Rabbits are an ongoing problem in this garden. Seems they love her Angelina sedum, coprosma, and Rose Campion as much as she does. Little 12" tall fences surround several of the beds which looks comical but apparently works as the rabbits don't like to jump over them.

Stained urbanite has been stacked by the owner to make short retaining walls and the look is quite classy blending in the flagstone and gravel paths. She explained how easy it was to stain the broken concrete from the old driveway by slapping on some concrete stain. "Piece of cake", she told me.

Other flower beds she edged with Sonoma fieldstone, stacking them herself. At every turn you can see the personal touches that make a garden unique. An old rusty mailbox was tucked into one of the beds overflowing with blooming pansies and million bells calibrachoa.  I loved this garden.

Next stop was another garden 30 years in the making. You won't believe the "before" pictures when you see this garden now. I could barely see the potential in the old pictures but the owner could and started to build up the rock hard soil bed by bed. After many years she has created  an organic garden full of flowering rhododendron, roses, viburnum, herbs, vegetables, citrus, apples and a 5 year old  Staghorn fern that measures 4 ft across.

The owner explained that deer are not a problem because they won't jump the irregular picket fence. Seems the wide pickets confuse their eyesight. Unfortunately, the gophers have decided recently that after 14 years, her camellias are now on the menu and she has lost almost all of the original 40 in the past year. Instead of lamenting her loss, she sees it as an opportunity to add new plants. She has the optimism that all gardeners possess.

Chickadees nested in a box attached to the porch. Garter snakes and alligator lizards patrol the flower beds. A bathtub, sunk into the earth serves as "the poor man's hot tub". Old metal chairs are planted with flowers and ferns and other found garden art is sprinkled generously though out the garden. This is the garden of an artist whose studio is nestled back among the trees. At every turn you feel the peacefulness of this wonderful place. This is a garden to experience not just view.

The last garden I was lucky enough to preview, was an asphalt driveway just 6 short years ago. There are occasional unplanted spots that still show asphalt. What a transformation. With the help of lots of top soil and an auger this gardener has created a spectacular space.  "Everything grows like crazy here", she explained.

The front garden is open to deer and is planted with echium, leucospermum, arctotis, barberry, thyme, rosemary and New Zealand flax. One of her favorite plants is a huge variegated holly that buzzed so loudly with bees I thought the electrical line coming into the house was making all the racket.

In the back, a small orchard edged the fence. Blooming lilacs by the deck heavily scented the air. Succulents intermingle with peony, erysimum and gaura. This gardener explained she " she is one of those people who buys whatever she likes and then finds a place for it". Having had previous experience growing grapes and olives in Sonoma, she is a hands-on gardener who does it all herself. She's a self-described  "drip queen".

A ceramic artist, her sculptures are focal points though out the garden. There is a lot of other garden art in this garden, too.

Where do these gardeners find the garden art, water features and other items that give their gardens that personal touch? One explained, she is always on the lookout for estate sales as she drives around or sees advertised in the paper. "That's were you can really find the treasures", she explained. "Little old ladies have some great plants and other wonderful finds in the back of the garden".

The Hidden Gardens of Bonny Doon Tour takes place Saturday and Sunday, May 19th and 20th. Don't miss it.
 

A Ben Lomond Garden Coexists with Deer

One of the perks of writing this gardening column for the Press Banner is being invited to visit beautiful gardens. I  recently had the honor to tour the garden of fellow columnist, Colly Gruczelak, writer of Plain Talk About Food, at her home in Ben Lomond. I've known Colly for many years going back to when she moved here in 2004 from Thousand Oaks.  If you know Colly it will come as no surprise that she is just as enthusiastic about plants as she is about good food. She gardens with a resident deer population and had lots to say about this dilemma.

When she first moved to the Ben Lomond property there was "nothing in the garden but bottlebrush and bare ground" she said. Not wanting to fence the property she has come to know what the deer are not interested in eating for dinner- in her garden anyway. Located right on the San Lorenzo River, her garden blends perfectly with the natural woodland setting.

A huge Fragrantissima Improved rhododendron poked its beautiful white flower trusses through an ornamental low fence. A Sally Holmes rose bloomed atop the fence, too. Colly explained she has included several roses in the garden and will spray them with a bitter repellent if the deer become too interested but often surrounding a rose with plants the deer don't like is enough to keep the buds safe.

A beautiful purple Grand Slam rhododendron bloomed nearby. Colly keeps plant tags in her Sunset Western Gardening book so she can look up a plants name when necessary. Given the hundreds of beautiful specimens in the garden this is no easy task.

I was surprised to see so many azaleas blooming in the garden. I knew rhododendrons are deer resistant but it surprised me to learn that her azaleas thrive also . Colly grows Encore azaleas that bloom continually throughout the season. They border all the garden paths and this first flush of flowers was spectacular.

She has an Iceberg rose intertwined with a Jackmanii clematis. The buds of the clematis were not quite open but I can imagine how stunning this purple and white combination will be. I love Iceberg roses. They scent the air with honey and vanilla. Colly doesn't worry about pruning the clematis according to the book. She "leaves it alone" and from the looks of the many buds about to burst with color it's doing just fine.

Another gardening tip Colly shared with me is her use of bungee cords to quickly hold up a plant until she has the time to tie it up properly. She buys 5 of these cords for a dollar and swears by their usefulness.

We stopped to admire a Cherokee Brave dogwood in full bloom. Underneath,  blue violet columbines covered the ground. As they reseed the patch grows larger and larger. The blue and pink made a breathtaking  combination blooming at the same time.

As we strolled through the garden I saw many other plants happily growing in spite of the deer. Fragrant daphne, fuchsia thymifolia, Australian fuchsia, Jack Frost brunnera, Mt. Tamboritha grevillea, lily-of-the-valley and Cape plumbago were all untouched. It surprised me to hear that she is replacing a large stand of white rockrose with Kaleidescope abelia. Seems her deer loved this rockrose and "ate it to the ground". Go figure about rockroses. Along her road there were lots of the dark pink variety not even nibbled in the slightest.

We finished our tour at the new sitting area she has created to enjoy with her husband in the evening. I'm sure it's the perfect way to end the day.
 

Zauchneria & other Favorite Plants for the Santa Cruz Mountains

I don't have room for any new plants. Really I don't, but come spring I just can't help myself. Every pretty plant I see in a nursery or at a friend's house, I want. Admiring from afar just won't do. I rationalize that if I choose from plants that will do well in my specific environment then it's OK to add something new to the garden. If you want to be armed with a check list of possible new plants that are almost guaranteed to do well in your own neck of the woods and without a lot of water, here are some good choices.

For those who live in the sun, consider a brilliant red California fuchsia. Hummingbirds and butterflies are both attracted to zauschneria which starts blooming in summer and continues through fall. They provide a principle nectar source for hummingbirds though the hottest, driest season. Deer aren't interested in them, either.

Ghostly Red is one of my favorites for sunny slopes although it will grow in some shade and is tolerant of many soils including alkaline, sand, clay and serpentine. The foliage is grey-green and shows off the intensely red flowers. It grows about 1-2 feet tall which is tall enough to attract the hummingbirds but low enough to be neat and tidy. Each plant can spread to 5 feet wide.

Another good variety of California fuchsia is Everett's Choice. This fast growing groundcover has dark orange-red flowers on a low, spreading plant. Furry grey foliage creeps along the ground and looks beautiful next to a path or rock wall. It's drought tolerant but will look fuller with an occasional drink after it's established. As with all California fuchsia a hard winter pruning will produce a denser plant the following year.

Consider combining either of these grey-leaved California fuchsias with the new Black Adder phormium to make a dramatic statement in your garden. Black Adder was bred from the deep, deep brown Platt's Black phormium but its color is even more striking. Deep, burgundy-black leaves have a high gloss overlay which eliminates sun fading. Black Adder is a strong and healthy grower with an upright but not stiff architectural form. When mature it reaches 3 ft tall by 3 ft wide so fits nicely into the garden.

Originally native to New Zealand, phormiums are also known as flax and their hemp-like plant fibers were traditionally used by New Zealand's Maori people to make rope, baskets and cloth.

Other good companion plants for California fuchsia are Bee's Bliss salvia, Western redbud, rockrose, buckwheat, armeria maritima, deer grass and ground morning glory. Ceanothus, rosemary and manzanita also look good with California fuchsias.

Shady gardeners ( no, I'm not making a moral judgement here ) or should I say gardeners who live in the shade or have portions of their gardens in the shade, have lots of plants to tempt them. Favorite plants for dry shade include flowering currant which is so spectacular at this time of year. This shrub blooms with huge clusters of pink, rose or white flowers. Other plants that attract hummingbirds in bright shade are Western columbine, bleeding heart, heuchera and mimulus. You can find these in a rainbow of beautiful colors these days.  Humminbirds love salvia spathacea so much they're called Hummingbird flower. Also suitable for planting under oaks are Douglas iris. I love the white Pacific Coast hybrid variety, Canyon Snow. Their white flowers make an area under tall trees come alive.

A couple of new additions to the garden would be fun especially if they don't use up your water budget. With a little planning you can have color, attract wildlife and have water for the vegetable garden, too.
