Colorful Plant Combinations for the Santa Cruz Mtns

Leave a comment

Fall is the perfect time of year for many things– long drives, walks in the forest, beautiful sunsets. It's also a great time of year to transplant those plants in your garden that aren't in quite the right place and to create new exciting combinations of foliage, color and texture that are just perfect.

I"m always newly inspired when I see common plants combined in ways I hadn't thought of. Some vignettes are simple repetitions of just two plants while others might include 3-4 plants with different characteristics. A recent meeting of APLD ( Association of Professional Landscape Designers ) of which I am a member, showcased fabulous ideas for plant combinations. In addition to these plants looking great together visually they share the same cultural requirements which is a must. No sense planting a water-loving partial shade plant next to a low water use plant that requires full sun.

Here are some of the awesome plant combinations from gardens I have designed and from fellow designers that I think are particularly appropriate for our area.

In a sunny garden colorful flowers surrounded by soothing green foliage creates a space to linger. The hummingbirds and butterflies attracted to the nectar of the flowers are an added bonus. The plants that create this beautiful scene combine strong, linear leaves from phormium 'Amazing Red'  with the golden foliage of abelia 'Kaleidescope'. Bright red and white flowers of the hummingbird-magnet salvia 'Hot Lips' combined with the soft green needles of grevillea lanigera 'Mt.Tamboritha' and the salmon pink flower spikes of phygelius (Cape Fuchsia) invite you to sit awhile in this garden.

Plant combinations that echo each other in color work well together. Think of the famous White Garden at Sissinghurst Castle in England. Phormium 'Cream Delight' looks great with so many plants the combinations are nearly endless. Consider growing it with Elijah Blue fescue grass and surrounding the group with a hardy groundcover like the succulent semperviven ( Hens and Chicks ).

Silver or grey foliage always looks smart when paired with pink shades.  Again that go-to plant that adds architectural interest, Phormium 'Evening Glow', provides the pink element with bronze edged leaves with red centers as does the dusty rose color of Sedum 'Autumn Joy' flower clusters.  Add the silver foliage of euphorbia wulfenii ' Glacier Blue' and Russian sage to complete the look.

Another group of plants that combine well have flowers of similar color. Hardy geranium 'Rozanne' with violet blue flowers pairs well with the soft blue ground morning glory, lavender-blue flowering catmint and penstemon 'Blue Bedder'. These perennials all grow in full sun but can tolerate some shade and like moderate watering.

Other combinations that might look great in your own garden include natives mimulus, juncus patens and deer grass with Pacific wax myrtle.  Or try growing Verbena lilacina 'De La Mina' alongside the blue tones of festuca californica. Under native oaks, heuchera maxima along with iris douglasonii won't require much summer water which will make the oaks happy too.

At this time of year I'm always drawn to combinations with warm, rusty tones. Purple smoke bush fall foliage pops when combined with gold flowering rudbeckia Goldsturm and purple coneflowers. Or how about Apricot Sunrise agastache growing with Spanish lavender and Big Ears lamb's ears?  Then again you might like the gold flowers of Harmony kangaroo paw blooming for months alongside Carex testacea (Orange Sedge).

Shady spots needing some pizazz could look to the huge leaves of bergenia 'Bressingham Ruby' with their brilliant magenta late winter flower spikes and combine it with golden yellow sweet flag (Acorus 'Ogon'). Another combination I like for the shade is asparagus spregeri and blue flowering Dalmation Bellflower groundcover.

Whether you're transplanting existing plants in new exciting combinations or creating new ones, fall is a great time to spend time in the garden.

Fall Color Trees for the Santa Cruz Mountains

Leave a comment

Walking around my neighborhood I see neon red fall foliage at every turn. Japanese maples covered with vivid red, bright orange or yellow leaves steal the scene wherever they grow. Surrounded by greenery Canadian redbud now pop with burgundy and yellow color. Flowering dogwood look like they're on fire. Because we live among so many trees and shrubs that stay evergreen in winter, fall color is especially important for us. What plants put on a good show in our area?

We are all familiar with the brilliant fall color of Japanese maples. Bloodgood is probably the single most popular upright purple-leaved variety seen in gardens. Beautiful in color and form, it's easy to grow and fits nicely in the smaller garden. Mine is covered with glowing red foliage now even though it grows year round in the shade.

My Coral Bark Japanese maple has had glowing golden and red foliage since early September. It's one of the earliest to start coloring in fall and make quite a statement in the garden when combined with warm-toned plants like heauchere 'Creme Brulee'.  I love this tree as it grows more upright and looks great near an entry as an accent. That luminous spark of lighter color is beautiful next to the deep reds of the other trees.

I surveyed some fellow designers for their favorite fall color varieties and found another Japanese maple favored not only for fall foliage color but the purple leaf color maintained during the summer even in hot situations. Called Red Emperor it's a moderate grower to 15 ft tall and wide. Like other Japanese maples it needs regular watering-weekly or more often in extreme heat especially during the first growing season to establish a deep, extensive root system. Watering can be reduced after establishment. Keeping mulch over the root zone is vitally important in our hot summers. Japanese maples look dramatic when planted with Japanese Forest grass, deer fern, flowering cherry and coral Bells.

Another favorite of mine for fall color is Crape Myrtle. You see them covered with large, colorful flowers starting in summer and lasting through fall. They are planted everywhere for good reason. Easy to grow and fast growing they take heat or cool coastal conditions. They are not fussy about soil and ask only for deep but infrequent watering. As if the flower color weren't enough to attract you, they absolutely glow in the fall with shades of red, orange and yellow. I'm partial to purple flowers so varieties like Catawba, Muskogee and Zuni top my list. Watermelon red and other bright red flowering varieties are also popular.

A great tree for the gardener interested in edibles is the Fuyu persimmon. This beautiful small tree is ornamental with glossy green leaves and also offers a dramatic fall display in shades of yellow, orange and red. Bright orange fruit begins to develop in late October and clings to bare branches usually through December. The tree looks more like it's covered with holiday ornaments than fruit.

Chinese pistache is a good tree for a patio, lawn or streetside. They can get by with almost no water but will tolerate lawn watering if drainage is good. Luminous orange to red fall foliage color is reliable even in mild winter areas. They are usually grown from seedlings.  When you buy one, it might be either male or female but a male tree without berries will develop better color.

Other trees with vivid autumn color that also do well in our area include red maples like October Glory and Autumn blaze, liquidamber, ginkgo, ornamental pear, cherry or crabapple, dogwood, goldenrain, locust, katsura, oak, redbud, sumac. All add to the fall drama of the landscape.
 
Now through late fall is a good time to shop for trees that change colors because you can see in person just what shade of crimson, orange, scarlet or gold they will be. I'm off to the eastern side of the Sierra to see for myself the Black oak and Quaking aspen fall color.

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.
