The November Garden

Leave a comment

Cercis_Forest_PansyOutside my window, the Forest Pansy Redbud has started to display its spectacular burnt orange fall color. There?s a suet feeder hanging from the branches so I get to enjoy the antics of the Pygmy Nuthatches, Purple Finches and the Chestnut-backed Chickadees all day long as I watch the changing colors of the foliage. Out back I have a Catawba Crape Myrtle also starting to show fall color. Its leaves are turning a rich butterscotch shade which is lovely but not the reddish-orange described in the books. What causes fall color to vary from plant to plant? How does location in the garden, weather, climate and growing conditions affect what you see each fall?

The brilliant fall color we see in the leaves of trees and plants is always there. It?s just masked by Japanese_Maple-fall_color.1280chlorophyll during the growing season as the plant is busy making food while the sun shines during photosynthesis. Come autumn, shorter days and cooler temperatures cause the trees to switch into energy-storage mode, at which point their leaves stop producing chlorophyll. For the few weeks before the leave fall to the ground, they are colored only by their natural pigments. It’s these colors – red and purple anthocyanins and yellow and orange carotenoids that make fall foliage so glorious.

Some years the show is more dramatic than others. The best conditions for intense leaf color to develop are dry sunny days followed by cool, but not freezing nights. A warm, wet autumn will almost surely result in less-than-spectacular foliage because the process of chlorophyll loss will be less consistent. Freezing temperatures or winds meanwhile can cause leaves to drop suddenly denying them opportunity to enter their slow, colorful dormancy. Finally, trees that are under stress because of pests, disease, injury or drought may drop their leaves with no color change at all.

Japanese_Maple-fall_color2.1280So if your garden becomes shady early in the fall this may result in less vivid fall foliage. If your trees are stressed by drought like this year you may not get the usual colorful fall display. These and the above factors all affect the intensity of fall foliage colors.

Now is a good time to shop for plants and trees that can punch up the color of fall in your garden. Seeing your new addition in person will show you exactly what color you are going to get. Sure Autumn Gold Ginkgo will probably always color up bright yellow and Sango Kaku Japanese maples will show off their characteristic golden foliage but the fall color of Purple Smoke Bush, Katsura tree, Witch Hazel, Pomegranate, Oakleaf Hydrangea and Blueberry, to name just a few, can vary.

First Frost
I received an email from someone new to the area about when to expect our first frost. I’ve kept a weather Japanese_Maple_Sango-Kaku_fall_color.1600journal since 1992 and based on my records occasionally we get a light frost at the end of October. Mostly though, the earliest frost has occurred about second week of November with late November being the most common. Be prepared by moving frost tender plants under overhangs if possible or having frost blankets (not plastic) ready to cover delicate plants.

Transplanting in Fall
Need to move a plant or install plants out of containers and into the garden soil? Now through February offers the best time to do this. Soils are still warm at this time of year which helps new roots get established quicker than in later winter.

Prepare the new location first before excavating any plant. Dig a hole twice as wide as the rootball, but just the same depth. Use a sharp spade to make clean cuts through roots. Cut roots will form new, dense and healthy roots.

Before replanting, especially from a container, check for roots that have circled the interior of the pot. These must be tugged loose and straightened when planted. Don’t be shy about loosening roots. When replanting be certain to keep the rootball at the same level it was and don’t add soil over the rootball. Most plants need oxygen at the soil level.

The Mountain Gardener’s Favorite Plant Combinations

Leave a comment

combination_loropetalum-pieris-dianellaI love my smart phone. I can?t imagine a day without it. A friend of mine told me that I would discover uses that I could only have imagined when I first got it. One of the simple things I use it for is taking pictures. Since I always have it in my back pocket I can whip it out in gardens, nurseries, in the wild or in any landscape that catches my attention.

It wasn?t until I started photographing gardens that I realized the importance of combining plants. So now when I design a grouping of plants that look good together I?m thinking of strong foliage plants, colorful flower spikes alongside soft mounds of foliage and delicate flowers alongside bolder blooms.

With the first day of fall next week I?m thinking of ways that will have any garden bursting with interest for the next few months. These are strategies for combining plants that are adaptable to all types of garden conditions whether you live in the sun or the shade and will also look good in other seasons of the year.

A vignette is a small group of plants that make a pleasing scene because of theirplant_combo2-phormium_CreamDelight-blueFescue-sempervivum complementary and contrasting features. I have several lists of good plant combinations that I regularly refer to when designing a garden. I usually start with a strong foliage plant then add other plants that have interesting texture, form or color.

When you look at a garden that you admire it?s usually the dramatic form of one of the plants that draws you in. When you use a plant with a bold, architectural form it makes a statement. The spiky foliage of Cream Delight phormium alongside a Burgundy loropetalum would make a good combination. Or how about creating a vignette of Festival Burgundy cordyline with Annabelle hydrangea and Cream de Mint pittosporum?

During the next few months plants begin to show soft, fall colors. Combine the fading foliage of these plants with plants that complement each other. The reddish fall color or Oakleaf hydrangea along with the pinkish-tan color of their fading flowers looks wonderful when combined with Japanese Forest Grass as it turns pink before winter. Another complementary fall combination is Royal Purple Smoke Tree surrounded by a bed of Autumn Joy sedum.

OLYMPUS DIGITAL CAMERAStrong colors sometimes contrast instead of blend when plants change colors in the fall. I like to tone down a combination with silver foliage. An example of this would be a plant grouping of Evening Glow phormium, sedum Autumn Joy and Glacier Blue or Tasmanian Tiger euphorbia.

Another way to create a great plant combination is by blending textures. Coral Bark Japanese maple and Plum Passion nandina work well together. Cistus Sunset with Spanish lavender and rosemary is another good combination. I also like a large mass of Blue Oat Grass and Salmon salvia greggii planted together. Santa Barbara daisy goes well with Red Fountain Grass.

My list of potential plant combinations is pretty long as I?ve made notes over the years. Each garden has its own personality and growing conditions. A hot, dry garden might depend on a ground cover ceanothus along with lavender while a shadier garden might use natives like heuchera maxima, iris douglasiana, yerba buena and salvia spathacea. Whatever plants you choose, let them work together to make exciting vignettes in your garden.

Beni Kawa Japanese Maple

Leave a comment

Last fall my sister lost her favorite tree in a windstorm. She lives on Fox Island in the southern part of Puget Sound. I remember hearing about the extraordinary Pacific storm on the national news shattering records in the Northwest. Gusts up to 76 mph closed bridges, falling trees hurt 2 people and thousands lost power. Her Silk Tree didn’t stand a chance.

Won_Yang_JanWhile visiting over the Christmas holiday I thought it would be a nice present to replace her dearly departed tree. Several nice ornamental trees made the short list including the Katsura tree with leaves that smell like vanilla in the fall and Forest Pansy redbud with magenta spring flowers, burgundy heart-shaped summer leaves and reddish-orange fall color. We also considered the native Pacific dogwood but she already had one in the yard. Driving around we started to notice the beautiful color of the Coral Bark Japanese maples in many landscapes and the decision was made.

I knew we would have no trouble finding a good specimen in the Pacific Northwest and I was right. Close Won_Yang_graftsby in Gig Harbor we found Yang’s Nursery and I walked into the realm of a Japanese maple expert. Owner Won Yang opened the nursery to give us a tour of the grounds.? We walked between rows of hundreds of maples and marveled at the huge bonsai specimens of Weeping Katsura tree, Harry Lauder’s Walking Stick, several different conifers and a very impressive, beautifully pruned Oshio Beni Japanese maple all over 20 years old.

Won showed us his greenhouses where he propagates the maples himself. He has been in the business for 30 years so he knows his stuff. Starting with a small green maple seedling with a half inch stem that is cut off 6″ above the ground,? he carefully grafts a tiny tip of new growth from the desired specimen onto the larger stem. It will take at least 3 years before the new tree will be big enough to sell. Won’s pride in his work was apparent as he smiled at the rows of newly grafted maples.

Acer_palmatum_Beni_KawaBack out among the maples, I had my eye on the rows of coral barked Sangu Kaku maples when I saw them. Lined up alongside were several trees with bark so bright I couldn’t believe my eyes. “What are these”, I asked? Won just smiled and told me they were called Beni Kawa Japanese maples and were a cultivar originally developed in 1987. They are prized for their brilliant salmon red bark which is much brighter than the regular coral bark maple. I was hooked. How could I not plant this gorgeous tree in my sister’s yard?

I learned that the bark of this tree can be polished to keep the bright color. Lichen often grows on older trees hiding the salmon red bark of the new branches. I’ll have to try using a soft cloth on my coral bark maple and see how it turns out. The Beni Kawa is a fast growing Japanese maple that will eventually reach 10-15 ft tall and 5-12 ft wide. It is hardy to 15 degrees.

Won grows his trees in a 50/50 mixture of top soil blend and fine crushed bark. He fertilizes with a balanced granular fertilizer and prunes in the winter. The 6 ft tree I bought my sister will not need to be pruned for a couple of years allowing it to establish a strong root system.

I’m looking forward to seeing how the new tree evolves as it grows especially since I know where this Beni Kawa Japanese maple was born.

Why We Love Trees

When you look out your windows into your landscaping what catches your eye first? Maybe the hydrangeas are looking beautiful about now covered with giant flowers in sky blue, dark pink or white. Maybe it's the purple and red spikes of your salvias that both you and the hummingbirds enjoy. But I'll bet the most majestic and inspiring sight in your garden are the trees that frame your house giving it a sense of permanence, welcoming you home and providing a haven for songbirds that serenade you on a spring day.

cornus_capitata_closeupLarge or small trees make the world go round. They produce oxygen and act as a giant filter that cleans the air we breathe. A mature leafy tree produces as much oxygen in a season as 10 people inhale in a year.

Trees clean the soil by absorbing dangerous chemicals and other pollutants that have entered the soil. They can either store harmful pollutants or actually change the pollutant into a less harmful form. Trees can filter sewage and clean water that runs off into our streams. They can absorb and lock away carbon dioxide as wood so it is not available as greenhouse gasses.

If you live near a busy street trees can muffle the noise almost as effectively as a stone wall. They also act as a windbreak during windy and cold seasons reducing the drying effect of the wind and keeping it from blowing  precious topsoil away.

Trees slow storm water runoff helping to recharge our Santa Margarita and Lompico aquifers. On top of all the cool things trees do for us they provide shade and cool us in the summer. In the winter they break up the wind reducing heating costs. Trees increase property values.

If you've been thinking about adding a few trees to your own property here are some of my favorites. Some don't get enough recognition and some are classics. All make great additions to the garden.

Early in spring the flowering plums and cherries let us know that winter is over and a new season has begun. Then the dogwoods start to bloom and we're awestruck. Maybe you know of an especially beautiful specimen that gets your attention each year when it blooms. There are a couple varieties that I like to include in designs that are easy to grow and live for many decades.

Introduced to me by Barrie Coate, the renowned arborist and horticultural consultant, the Evergreen cornus_capitataDogwood, Cornus capitata, is also known as Himalayan flowering dogwood and lives up to its name in every respect. This under used tree is breathtaking in late spring and early summer with large flower bracts over 3" across.  A friend has one in her garden and it is the showiest tree on her property for several months. This variety is slow growing reaching 20 ft tall in sun or partial shade after about 25 years. After flowering, red fruit provides a treat for the birds.

Another dogwood variety that makes a wonderful addition to the garden is the Venus dogwood. I've heard it said that some consider it even showier than the Evergreen dogwood but I like them all. It's a fast growing deciduous hybrid with white flowers as large as your hand. Summer flowers give way to strawberry-like fall fruit as the leaves turn color. It's highly resistant to disease and drought conditions.  What's not to love? I also recommend Cornus Eddie's White Wonder for it's beauty and disease resistance.

If you would like a tree in a certain spot but don't have lots of room, consider  a Drimys winteri, commonly known as Winter's Bark. This evergreen, slender tree from Chile has aromatic mahogany-red bark which cured sailors in past centuries from scurvy and leathery fragrant leaves. Small clusters of jasmine-scented, creamy white flower appear in winter and spring. It grows to only 20 feet tall.

Other trees that are favorites of mine include Forest Pansy redbud for its stunning red foliage and Sango Kaku Japanese maple for its year round interest. Arbutus Marina, Oklahoma Texas redbud and Tristania laurina Elegant are also wonderful trees for the landscape.

Plant a tree for yourself and future generations.

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.
