“Oh Deer” – Part 1

This young buck at Quail Hollow is perfectly happy browsing on the native plants that grow there.

I thought my plants were safe from deer. Because most of my sunny spots are in front, I planted lots of colorful annuals and perennials out there. Then a couple months ago, all my snapdragon flower spikes were eaten overnight. I was stymied. I live in a condominium complex, after all. Then the buds of my agapanthus were severed and the snapdragons for the second time. It was then that my neighbor told me she had captured a young buck on her security camera heading right for my plants.

So I now spray with Squirrel Stopper (I have a squirrel problem, too) as it’s similar to some of the deer repellents with rosemary oil, corn mint oil, putrescent eggs solids and cinnamon oil. I don’t need to spray the zinnias, cosmos, geraniums, petunias or even the large hostas, just the snapdragons. Picky deer, I guess. But are there any other safe plants that deer seem to avoid?

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.
Next week I’ll give you some good techniques that help deter deer.

Planting California Natives in the Fall

In the California native plant garden at Gamble Garden this coral bells provides a beautiful focal point and the hummingbirds love it also.

When my optometrist was in Palo Alto I used to stop by Gamble Gardens on Waverly Street to see what was in bloom. Just down from Steve Jobs house, this historic garden dating back to 1908 is aa treasure. Over 300 volunteers keep the garden looking beautiful and it’s open to the public for free every day. The California native plant garden is one of my favorite areas. Fall is the perfect time to plant in your garden. Here are some ideas.

By planting from mid-September through mid-November, roots of all plants have a chance to grow during fall and most of the winter without having to supply nourishment to the leafy portion of the plant. Roots of deciduous plants still grow even after plants drop their foliage as long as the ground temperature is above 50 degrees. Cooler day and night temperatures slowly harden off the top of the plant to prepare for the cold days of winter.

Another reason that fall is the “no-fail” planting season is because plants put in the ground in fall need less water to establish. The plants themselves use less water since photosynthesis is slowed by shorter days even if it’s occasionally warm. Evaporation rates slow down also during fall so moisture in the soil lasts longer as well. Sometimes we get lucky with fall and winter rains perfectly spaced so the ground never completely dries out. Unfortunately this winter is predicted to be another La Nina but let’s hope we get more rain than last season.

Plants that thrive in dry, shady spots benefit especially from fall planting as they need established root systems before next years dry season. Dry shade sometimes occurs in places beyond the reach of the hose but also under native oaks. To protect the health of native oaks, it’s a requirement that plants underneath thrive with little or no summer irrigation.

King Edward VII Pink Flowering Currant

Plants of proven success under these conditions include native currants and gooseberry. Red flowering currant is a show stopper capable of controlling erosion. In the spring, the long, flower clusters of this deciduous shrub will dominate your garden. There are many selections to choose from so if the huge white flowers appeal to you ‘White Icicle’ will be beautiful in your landscape. ‘Barrie Coate’ and ‘King Edward VII’ have spectacular deep red flower clusters and ‘’Spring Showers’’ has 8″ long pink ones. Grow in full sun to partial shade. This California native requires little water once established and is a valuable nectar source for hummingbirds.

Some other good California native shrubs for erosion control are western redbud, mountain mahogany, western mock orange, lemonade berry, toyon, snowberry, matilija poppy and western elderberry. Rbes viburnifolium, creeping mahonia, snowberry, ceanothus maritimus and ‘Anchor Bay’s are good groundcover selections.

Pacific Coast Iris ( iris douglasiana )

Smaller natives that put down deep roots are heuchera, iris dougasiana, native grasses, yarrow, coast aster, California fuchsia, wild grape, mimulus, buckwheat, wild rose, sage and salvia.

Bush Poppy

Bush poppy (dendromecon rigid) is another native found right here in our area and needs no irrigation at all once established. Beautiful bright yellow, poppy-like flowers cover the plant in spring. They can be propagated from cuttings taken in summer and are pest and disease free.

Remember when setting plants on a steep slope to arrange them in staggered rows. Make an individual terrace for each plant and create a basin or low spot behind each one (not around the stem) to catch water. Set the crowns of the plants high so they won’t become saturated and rot after watering and make sure mulch does not build up around the stem.

These are a Few of my Favorite Plants

While staying at a friend?s house during the evacuation I was able to stroll through her garden. She?s also a landscape designer and her garden is as beautiful as you?d imagine. She?s addicted to plants and keeps adding to her megs collection on a regular basis. Among the blooming perennials I came across were some of my person favorites. All three are wonderful low water, wildlife and pollinator friendly plants.

Epilobium ‘Everett’s Choice’

The first plant that caught my eye was an epilobium ?Everett?s Choice?. The name Epilobium is considered current but this group of sub-shrubs used to be called Zauschneria and are so different from the other epilobiums like Fireweed that many California native plant enthusiasts and even the experts often still refer to them as Zauschneria.

This low-growing vigorous ground-hugging shrub remains under 6 inches tall by up to 4 to 5 feet wide with fuzzy gray-green leaves that are covered with long whitish hairs. Vivid red-orange tubular flowers are produced in profusion in the late summer into fall. It does best in full sun but will tolerate some shade. Quite drought tolerant, but remains a fuller and more attractive plant with an occasional summer watering. It likes well-drained soil best but will do OK in heavier soils if not over watered. California fuchsia are deer resistant and attractive to hummingbirds.

Echo Mango kniphofia

The second plant that caught my eye is also a hummingbird magnet. Kniphofia, also called Red Hot Poker blooms spring into summer with torch-like clusters that open from the bottom up. The selection at my friend?s garden was probably Echo Mango. Whether the cultivar blooms with red, yellow, orange or mango colored flowers this perennial grows to about 3 feet tall and 4 feet wide in full sun. It is evergreen and requires little summer water. Deer don?t like this plant either so that?s a plus and it?s hardy to below 15 degrees.

Sdum ‘Autumn Joy’

Many of you already grow sedum spectabile ?Autumn Joy?. A succulent perennial to 1-2 feet tall it has wide cabbage-like rosettes of pale blue-green leaves and rich, dark pink flowers that put on a spectacular show above foliage in summer and fall. Plant in sun in a dry well-drained soil and water however much or little you want. The foliage dies back in the winter but is root hardy to below -30 degrees. This group of sedum was given the prestigious Royal Horticultural Society?s Award of Garden Merit in 1993. Beautiful in the rock garden, perennial garden or spotted into a natural meadow setting it attracts bees and butterflies and is deer resistant. The seed heads can be left for winter interest as well as a food source for birds but stems should be removed prior to the new buds opening in February.

Any one of these plants would be a lovely addition to your garden if you don?t already grow them.

Ceanothus: The Most Valuable Plant in your Garden

Those of you who read my column regularly might have noticed I often write about plants that are valuable to the birds and the bees as well as butterflies and wildlife in the general. I have 10 bird feeders around my house. Four for the hummingbirds and the other six have black oil sunflower seed and hulled chips. At this time of year when there are so many young the extra food is much appreciated. I provide water and nectar plants for the bees and butterflies as well. If I had to choose one plant to grow that would provide the most benefit for all the critters it would be ceanothus. Hands down, it?s the best and here are some of my favorite varieties.

Ceanothus ‘Carmel Creeper’

Ceanothus ‘Heart’s Desire’

The groundcover varieties I have in my landscape are Anchor Bay, Carmel Creeper, Heart?s Desire, Centennial and Diamond Heights. If deer frequent your landscape you should stick with Anchor Bay, Heart?s Desire and Centennial but the others are great in protected areas.

One of the upright types I grow is ceanothus thysiflorus. It?s one of the earliest native shrubs to bloom in our area. Ceanothus thyrsiflorus grow along a narrow band close to the coast from Monterey to southern Oregon. I also grow Julia Phelps with those electric blue flowers and Ray Hartman.

A new variety I’ve recently learned about from my friend and fellow Press Banner columnist, Colly Gruczelak, is called Celestial Blue. She planted several 2 years ago from 4″ mail order sleeves and they are now 3 ft tall and 4 ft wide. In her sandy garden, home to her personal deer population, the flowers look like blueberry sherbet. With a light fragrance, described as grape tart, it makes a good screen or accent. This cultivar is probably a hybrid of Julia Phelps and Concha. A horticultural cultivar is simply a plant variety that’s been selected specifically for gardens. Celestial Blue flowers 9 months a year especially in the summer when it explodes with rich purplish blue flowers.

A great variety I often use when designing a garden is Ceanothus ?Concha? because it will accept summer water more forgivingly than most and tolerates clay soil more than other species.

Joyce Coulter ceanothus also tolerates clay, summer irrigation and shearing better than other cultivars. It?s a good bloomer, drought tolerant and is covered in spring with wildly fragrant blue three-inch flower spikes.

Ceanothus is often said to be short lived. Most varieties need good drainage, little summer water and don?t need soil amendments. In their wild conditions ceanothus plants have a natural life cycle of 10-15 years although some live longer.

Diamond Heights ceanothus

Several members of the ceanothus family can form a symbiotic relationship with soil micro-organisms and fungi, forming root nodules which fix nitrogen. This is a reason why fertilizing is not normally recommended. Adding fertilizer mights kill off the good micro-organisms. Ceanothus are better left fending for themselves.

Ceanothus provide excellent habitat for birds and insects. They are good for attracting bee and fly pollinators and are the larval host plants for the beautiful ceanothus silkmoth. Ceanothus seed is readily eaten by many local birds. Planting a ceanothus is an important step to attracting more birds and wildlife to your garden.

Early California Indians used the fresh or dried flowers of some varieties for washing, lathered into a soap. it has been said to relieve poison oak, eczema and rash.

California Natives for Erosion Control

Who knows what the weather will be like this winter but what we do know is that some of our rain events will come with a vengeance. It’s not that unusual for our area to get 8 inches of rainfall during a storm and that can create havoc on an unprotected hillside. Fortunately, October is a good time to do something about it.

Pink Flowering Currant

Fall is the perfect time to plant in our area. The soil is still warm encouraging root growth and the weather is mild. Using the right plants on hillsides can help slow and spread runoff and prevent soil erosion. Mulch also protects soil from direct rain impact and slows runoff across bare soils. Covering the steepest slopes with jute netting through which plants may be installed is an added precaution.

There are many attractive plants that work well for erosion control. Often they need to adapt to shallow, poor soil and cope with less than ideal conditions all while putting down dense, strong roots. California natives are well suited to this job.

Common native shrubs include ceanothus and manzanita of all

Calycanthus occidentalis

types. Calycanthus or Spicebush has fragrant flowers in late spring blooming well into summer with a spicy fragrance. The foliage is aromatic when crushed and changes from a spring green color to pale golden in autumn. Decorative woody fruits last into winter making this shrub attractive year round. It thrives with infrequent to moderate watering. Combine with coffeeberry and deer grass in sunnier spots or with Douglas iris and giant chain fern in shaded spots below trees. All these plants have deep roots and control erosion.

Ribes s. King Edward VII

Ribes sanguinem or Flowering Currant is another show stopper capable of controlling erosion. In the spring the long, flower clusters of this deciduous shrub will dominate your garden. Choose from white flowering ‘White Icicle’ or ?Barrie Coate” and ‘King Edward VII’ with spectacular deep red flower clusters. ‘Spring Showers’ has 8 inch long pink clusters. Grow in full sun to partial shade. This California native requires little water once established and is a valuable nectar source for hummingbirds.

Some other good California native shrubs for erosion control are western redbud, mountain mahogany, western mock orange, lemonade berry, toyon, matilija poppy and western elderberry. ribes viburnifolium, creeping mahonia and baccharis. Ceanothus maritimus, ?Heart?s Desire? and ?Anchor Bay? are all good groundcover selections and are not attractive to deer.

Symphoricarpos – Common Snowberry or Creeping Snowberry – can hold the soil on steep banks. This native tolerates poor soil, lower light and general neglect.

Smaller natives that put down deep roots are yarrow, coast aster, California fuchsia, wild grape, mimulus, buckwheat, wild rose, sage and salvia.

Bush poppy -dendromecon rigid- is another native found right here in our area and needs no irrigation at all once established. Beautiful bright yellow, poppy-like flowers cover the plant in spring. They can be propagated from cuttings taken in summer and are pest and disease free.

Remember when setting plants on a steep slope to arrange them in staggered rows. Make an individual terrace for each plant and create a basin or low spot behind each one – not around the stem – to catch water. Set the crowns of the plants high so they won’t become saturated and rot after watering and make sure mulch does not build up around the stem.

Favorite Plants of Landscape Designers

Big surprise. Many of my friends are also landscape designers. We get together to talk plants, garden design challenges and plant problems while enjoying good food along with a little wine thrown in for good measure. Recently we met in Corralitos to exchange favorite go-to plant ideas and tour the truly fabulous garden of our host. Filled with interesting foliage and texture as well as plants that flower over a long season we all came away excited to use them in our next design. Maybe some of these ideas will work in your own garden.

Fremontodendron californicum

Every interesting garden has good bones. A successful one has a focal point, garden rooms with ?walls? and a ?ceiling?, plants with different textures and foliage color, repetition and unity. My friend?s garden is no exception.

Rivaling for our attention from the breathtaking view of Monterey bay, a fremontodendron, in full bloom, was a real show stopper. This California native shrub requires little irrigation and provided the perfect backdrop to the entry garden.

Loropetalum / Agave ‘Blue Glow’

Other plants that brought this garden to life included a stunning Blue Glow agave paired with the burgundy foliage of loropetalum rubrum. Both have low water needs and aren?t attractive to deer.

Eggs and bacon plant

A small recirculating fountain tucked within a pocket garden provided an inviting lure for songbirds. Surrounded by the unique lotus corniculatus or eggs and bacon plant along with a tropical-looking melianthus major aka honey bush this garden room invited one to stick around for awhile.

We garden designers were impressed with the size and vigor of acacia ?Cousin Itt?. This lovely small plant with emerald green, feathery foliage stays small in the garden and has low water needs. Not to be confused with the bully acacia tree seen around here, it?s one of the good guys. Plant in full sun to partial shade.

Euphorbia wulfennii

In deer country you can?t go wrong with euphorbia characias wulfenii ?Bruce?s Dwarf?. It does an excellent job of seeding itself so beware. Grow it where it can self sow and not become a problem child. Very hardy in winter and water sparingly. In spring and summer the flower heads form at the branch tips covering the plant with a chartreuse color.

A French hybrid lilac called Pocahontas scented the air as we exchanged our favorite plants that pull a garden together. The winners included hardy geraniums like Biokovo and Karmina and California native heuchera maxima. Canyon Snow Pacific coast iris also got a lot of votes. Groundcover sedum ?Angelina? and lime thyme garnered support also.

Abelia ?Kaleidescope? and ?Confetti? got the nod from several of us. Also high on the list of favorite plants, the variegated gold and green cistus was used by many because of its low, mounding habit that hugs the ground and provides a bright evergreen accent to a sunny garden.

So if you?re in the mood to add a couple of interesting plants to your garden, take a tip from what landscape designers use or grow in their own gardens.
