The Mountain Gardener’s Favorite Plant Combinations

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.

Treats & Tips for the September Garden

salvia_m_Hot-LipsYou can feel the weather changing as summer winds down. It?s more than just the passing of the Labor Day holiday and the school year starting. The nights are longer and cooler. The days are not quite so hot and the flowers in the garden seem brighter and more colorful. I look past the soft blue and lavender blossoms and am drawn to the warm shades of gold, rust, orange, hot pink and red. They shout autumn is on the way.

There?s nothing quite like adding a few new perennials to brighten up the garden. There are many that don?t require a lot of water after they become established. I recently visited a garden where the irrigation was reduced to the point that that most of the plants were barely hanging on. But there among the crispy plants were two Hot Lips salvia blooming as big as you please. This plant is popular for a reason. Hummingbirds, butterflies and bees love it and it blooms for a long time. It stays compact and is a great carefree shrub for water wise gardens.

Daisy flowers always bring a smile to my face. As members of the composite family they have echinacea_Wild_Berrya flat landing surface for butterflies to land on. Coneflowers are one of my favorites. When they start blooming in the early summer I enjoy them both in the garden and as cut flowers inside. Some have a slight fragrance. Hybridizers have introduced beautiful shades of gold, yellow, orange, burgundy and coral in addition to the traditional purple and pure white. Because they are dormant in the winter they are good candidates for the garden that has summer sun but winter shade. They are not attractive to deer and are good additions to the low water garden.

gaillardiaAnother perennial that blooms throughout summer and fall is gaillardia also known as blanket flower. I?ve seen this tough plant grow in neglected gardens that the owner swears does nothing to keep it going. They are covered with dozens of large reddish-orange flowers with yellow edging and bloom over a long period. This plant also attracts butterflies. You can start perennials from seed at this time of year for next year?s bloom.

Don’t overlook the color of other foliage plants like Orange Libertia, Abelia ?Kaleidescope?, New Zealand flax, red fountain grass and Japanese bloodgrass in the garden.

Now through October, divide summer blooming perennials like agapanthus, coreopsis, daylily and penstemon that are overgrown and not flowering well. You can also divide spring blooming perennials like candytuft, columbine, astilbe, bergenia and bleeding heart but sometimes they don’t bloom the first spring afterwards due to the energy they use re-establishing themselves.

Another thing to do while out in the garden this month is to cut back berries vines that have produced fruit. Canes of the current season should be trained in their place.

Spider mites are especially prolific during hot, dry weather. Sometimes you don’t even know how bad the infestation is until all your leaves are pale with stippling. Periodically rinse dust and dirt off leaves with water. Spray the undersides of infected leaves with organics like insecticidal soap switching to neem oil if they build up a resistance to one of the pesticides.

Soon it will be time to start cool season veggies or plant cover crops in the garden. It?s never too soon to start planning for erosion control in those areas that caused you problems during last spring?s storms. But for now add some early fall color and have fun in the garden.

Garden Tasks for Late Fall

honey_mushroomsIt came out of the earth suddenly, pushing soil and plants that were in it’s way to the side. Just a bit of moisture had allowed this large clump of honey mushrooms to emerge and start its path to reproduction. At this time of year when the trees are turning the color of flame and some have already gone into dormancy it seems the earth is growing silent. Winter will soon be here. For nature life continues. Look around you and be thankful for the bounty, the restfulness, the time to enjoy these beautiful mountains that we call home.

The Giant Pacific salamanders in the forest duff are resting up for next seasons batch of young. Maybe now that we’ve had some rain the deer will have something to eat other than my garden. young_buckAs the weather cools, my garden plants are looking past their prime. The seed heads that remain invite small song birds to feast on what remains. Chickadees hop from plant to plant. They even find something to eat in the Japanese maple leaves and the old dried hydrangea flowers that have turned a dusty rose color. Spotted towhees scratch for seeds buried under fall leaves. I’m always slow to cut down and clear everything away but  there are some things I should be doing this autumn. I’ll pay if I leave everything for next spring when it all needs doing at once.

First, I’ll cut back perennials such as hostas, asters and mums, which collapse into a gooey mess and shelter slugs and snails. I’ll pick up and dispose of diseased  leaves, especially under the roses to prevent pathogens from spreading. Coneflowers, ligularia and rudbeckia flowers and ornamental grasses can stay to contribute winter interest for me and the birds.

I’ll leave as much foliage as possible to provide cover, protection from cold winds and foraging spots for other critters and good insects. I’ll wait to cut back the stems and foliages of not only the grasses but evergreen perennials, salvias, hardy fuchsias until spring. There are few things as rewarding as seeing your winter garden turn into a sanctuary for wildlife.

As weeds emerge I’ll spend a little time here and there keeping up with them. There are 300 dormant weed seeds per square inch of soil and I don’t want to add to that.

I don’t have the space to plant a cover crop so I like to top dress the soil with compost or bark chips. I have a few new trees that need staking to secure them through the winter. This prevents breakage and allows new roots to grow deep and stable. Be sure to set the stake on the windy side of the tree and tie loosely so it has some wiggle room This movement stimulates the trunk to grow thicker. Come next summer the trees will  probably be ready to stand on their own. I don’t want to keep them staked longer than necessary. Also check any trees or shrubs that were transplanted and are still tightly bound to a stake. Remove or reset the stake so the trunk will not become girdled as it grows.

OLYMPUS DIGITAL CAMERAA word about all those leaves that cover the ground, the lawn and the perennial beds at this time of year. You can build up your garden soil by running a mower over them to chop into smaller pieces and spread over the soil. Worms and other organisms will start to break them down right away. Next spring dig what’s left into the soil. If you leave more than an inch or two of whole leaves on top the rains will compact them into a soggy mess and prevent oxygen from reaching the soil. If you have too much of a good thing when it comes to leaves, it’s best to put them into your green waste can.

Hummingbirds still need a nectar source at this time of year. Anna’s hummingbirds live in this area all year long.  They need your nectar even more in the winter when very little is in bloom. My abutilons are a winter favorite for them in my garden. Keep your feeders up year-round and keep them clean.
