Gift Plants for your Christmas List

Leave a comment

I've barely finished eating leftover turkey a dozen different ways and already I find myself thinking of all things Christmas. I know I should relish Thanksgiving longer and not rush it but I can't help myself. I'm basically just a big kid at heart and there are so many fun gifts that come from the garden. Most of the people on my Christmas list live far from from here so I'm not giving anything away by sharing some of my gift ideas.

My Aunt Ruth is quite the gardener. I enjoy flowers of every kind whenever I visit her. There is always something in bloom.  She loves her neighbors who stop, talk and admire her landscape as she prunes or weeds. I'm going to give her a winter flowering camellia to spice things up at this time of year. Chansonette camellia hiemalis, a variety often classified with sasanquas will get heads turning. This easy to grow shrub is one of the most popular camellias for good reason. Rich pink, double flowers standout against the dark green foliage.  Spreading 6' tall and 8' wide this vigorous shrub is perfect to espalier on a trellis against a wall. They actually prefer winter sun and can tolerate more sun year round than other types of camellias. The beautiful flowers last a long time and will make my Aunt Ruth's garden the talk of the neighborhood.

My Aunt Rosemary lives in Concord in the Bay Area where it gets hot in the summer. The border around her patio would be perfect for a tea tree as it blooms for a long time and requires little or no water when established. They are called tea tree because Capt. Cook brewed a tea from the leaves and gave it to his crew to prevent scurvy. Just in case deer jump her fence they won't devour its needlelike leaves leaving her to enjoy the small showy flowers from winter until very late spring. I especially like the double white flowers on the variety Snow White as they really pop when combined with stronger colors.

My Aunt Alba especially likes fragrant flowers. In her garden she grows roses, gardenias, lilacs, sweet peas and pinks to name just a few. Fragrant Star erysimum would make the perfect addition to her perennial border. It blooms from spring until early fall with bright lemon yellow highly scented flowers. Radiant, variegated green and yellow foliage will stand out among her other flowers. As a bonus they are butterfly magnets. I've seen swallowtails visit this plants again and again on a sunny afternoon.

For those on my Christmas list that love California natives a Common Snowberry would make a great addition to their woodland garden or in the dry shade under oak trees. Seldom troubled by pests this small shrub can be used to control erosion and is deer resistant. Beautiful ornamental white fruits cover the plant at this time of year and are valued by varied thrush, robins and quail.

Creeping snowberry is similar and makes an excellent groundcover. Few shrubs work as well as creeping snowberry when situated under the dense canopy of a coast live oak. When combined with Hummingbird sage, Fuchsia Flowering gooseberry and coffeeberry they create  a woodland garden that provides nesting cover for birds as well as protective shelter for other wildlife.

I'm also working on some garden and nature inspired crafts but if I tell you I'd have to…well, you know.

Good Shrubs for Erosion Control in the Santa Cruz Mtns

Leave a comment

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.

Zauchneria & other Favorite Plants for the Santa Cruz Mountains

Leave a comment

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.
