Fall Gardens

Pineapple sage blooming now.

The end of daylight savings time signals to me that autumn is really here in our mild California surroundings. Enjoy these crisp mornings and warm days and to make your garden more compelling, try mixing in late flowering perennials as well as trees and shrubs with bold leaves and a wide range of autumn color.

Sasanqua camellia blooms from fall into winter.

Bright trees and shrubs add color flashes to fall gardens. Sasanqua camellias have already started blooming and will continue to flower throughout the winter. In addition to asters and rudbeckia, Japanese anemones are the stars of the border at this time of year. The electric blue flowers of dwarf plumbago contrast with reddish leaves as night temperatures dip, Encore azalea and Endless Summer hydrangea are blooming now, too.

Other perennials that are blooming now are California fuchsia, Pineapple sage and Mexican bush sage.

California fuchsia

I love my patch of California fuchsia. Starting in the summer and flowering through fall this California native is covered with orange or scarlet-orange flowers that attract hummingbirds like crazy. A great plant along the path or draping over a rock wall this perennial thrives in areas that might fry other plants. Also known as Epilobium canan or Zauschneria it is in the evening primrose family and native to dry slopes and chaparral especially in California.

Mexican Bush Sage

Mexican bush sage look great blooming alongside California fuchsia. Orange and blue are opposite on the color wheel so they look fabulous together. The bright red flower spikes of Pineapple sage look pretty nearby so the whole area is a hummingbird feast.

But what about vivid foliage in the garden? Which plants put on the best show in our area? Here are some of my favorites.

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. And have you priced persimmons in the store lately?

Blueberries are a must for the edible gardener. They make a beautiful hedge that provides showy red or yellow fall color. Because of our colder winters here in the mountains, we can grow both northern highbush which are self-fertile and southern highbush which produce better with another type to pollinize them. They can be great foundation plants around the home as well as in the garden.

A vine that lights up with the onset of autumn is Rogers Red California grape. If you have an arbor, wall or fence that need covering quickly, this is your plant. The green and gray leaves are transformed in autumn into great draperies of rich, scarlet red leaves with clusters of summer fruit turning all shades of purple.

Japanese barberries are deer resistant, low water-use small shrubs that make them superb hedge plants, background plants against fences and foundations or accent plants. Red or lime colored summer foliage changes to orange, red or amber in the fall. I love the graceful growing habit of many of the varieties but there are pillar forms and also dwarf types.

Bright foliage on trees like red maples, liquidamber, Chinese pistache, ginkgo, ornamental pear, cherry or crabapple, dogwood, goldenrain, locust, katsura, oak, redbud, sumac and witchhazel all add to the fall drama of the landscape.

Light up your garden as the light fades and the days shorten. I know my garden needs a greater variety of fall color than just the Japanese maples in pots on the deck and the barberries. I?m waiting for my purple smoke bush to turn luminous scarlet and add color flashes to my fall garden.

Halloween From the Garden

So many pumpkin varieties to choose from for decorating and eating.

Halloween is just around the corner and besides deciding what you or the kids are going to be this year, it’s time to bring in any plants that you plan to overwinter in the house. Whether they’re the houseplants that you put out on the patio for the summer or frost tender plants that you want to save, this is the time to bring them in and here’s why.

Although our nights are still above freezing, plants need to acclimate to the indoor environment before you start turning on the heater regularly. Be sure to wash them thoroughly and inspect them for any insects that may have taken up residence while they were vacationing outside. Usually you can dislodge any hitchhikers with a strong spray of water but if that doesn’t do the trick, spray them with a mild insecticidal soap or one of the other mild organic herbal sprays like oil of thyme.

Another tip: Fall is not a good time to prune. Wounds heal slowly, leaving them more susceptible to disease. As a general rule, don’t prune when leaves are falling or forming. Wait to prune most trees until late in the dormant season or late spring after leaves and needles form. To avoid sap flow on birches and maples, prune after leaves mature.

If you want to decorate for Halloween there is a plenty of plant material you can harvest from your own garden or nearby woods. Manzanita branches can often be found on the ground and make great arrangements combined with nandina or other berries. Some of the trees have started to turn color and their leaves can also be used for wreaths. The leaves of New Zealand flax last a long time and add fall color in bouquets.

Classic mums, pumpkin and Blue Hakkaido squash at my doorstep.

Mums are the classic fall flower. They come in nearly every color except blue and the flowers have many shapes from daisy to spider mums. They are perennials and make good additions to the garden. Best of all they make excellent cut flowers.

Several years ago a friend gave me a Blue Hokkaido winter squash to decorate my front entry and eat afterwards. It was delicious. This year, a good friend grew the Cinderella pumpkin (Rouge viv d?Etampes) which is said to have been the inspiration for Cinderella?s carriage. This French heirloom pumpkin was very popular during the 1880?s and will be tasty in pies and savory dishes later this fall. For now, the glowing orange-red color contrasts magically with the very pronounced lobes and flattened top.

Many gardeners feel the Cinderella pumpkin is the very best pumpkin to grow in your garden. It?s the first to set fruit, first to ripen and is mildew resistant. Their bright orange creamy flesh is perfect for baking. Oven roasted they produce a pumpkin puree that is neither watery or bitter. Delicious in pumpkin spice muffins, pumpkin soup, or with vegetables and sausage. I even found aa recipe for pumpkin mac n? cheese baked in a pumpkin. I?m so excited.

Pumpkin was a staple food for the early pioneers. It was easy to grow as a few seeds dropped into a shallow hole grew into a mature fruit. Yes, technically they are a fruit not a vegetable along with summer and winter squash and gourds. Their thick rind would allow them to be kept almost indefinitely.

If you decide to grow the Cinderella pumpkin next year, you can start inside in pots or wait to plant in the ground when night temps are 55 degrees or over. In the garden, group them with other deep rooted plants that grow rapidly and need lots of water such as corn, cucumbers, melons and tomatoes.

Fall Color in Your Backyard

Quaking aspen

Soon I?ll be hiking in the Sierra among the native dogwood and hoping I?m not too late to see fall foliage. Last year I enjoyed the display of Quaking Aspen near Ebbetts Pass on Highway 4. Did you know that a massive grove of 47,000 aspen in Utah is one of the largest organisms on the planet? They all share the same genetic material and a single root system. There is a contender for this renown in Oregon where a honey mushroom measuring 2.4 miles across lives in the Blue Mountains. Interesting stuff.

Bloodgood Japanese Maple

Around here I?m just starting to see some trees and shrubs put on their coat of many colors. In my own yard, I have a Bloodgood Japanese maple that has been in full color for a couple weeks now. None of my other maple varieties are showing any color but that?s okay as I?ll be able to enjoy the upcoming show for many months. That is, if strong winds don?t dry out the leaves prematurely. I?ve watered well hoping this won?t happen. Weather conditions play a major part in the intensity of fall color. The time of year is nearly consistent but 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.

Crape Myrtle

The vivid colors in a leaf are always there. They are just masked by the green chlorophyll which is busy making food by photosynthesis while the sun shines. Come autumn, shorter days and cooler temperatures cause the trees to switch into energy-storage mode and their leaves stop producing chlorophyll. For the few weeks before the leaf falls to the ground it is colored only by natural pigments. It’s these colors – red and purple anthocyanins, yellow and orange carotenoids – that make fall foliage so glorious, sometimes anyway.

Which plants put on the best show in our area? Here are some of my favorites.

Forest Pansy redbud

California native, Cercis occidentalis (Western redbud) turns yellow or red in the fall if conditions allow. This plant is truly a four-season plant starting in spring with magenta flowers, then leafing out with apple green heart shaped leaves. Colorful seed pods give way to fall color. This small native tree or large shrub does well as a patio tree in gardens with good drainage.

Other native plants like spicebush and Western azalea turn yellow or gold in the fall. A native vine that lights up with the onset of autumn is Rogers Red California grape. If you have an arbor, wall or fence that needs covering quickly this is your plant. The green and gray leaves are transformed in autumn into great draperies of rich, scarlet leaves with clusters of summer fruit turning all shades of purple.

Edibles that turn color in the fall include blueberries, pomegranate and persimmons.

Trees and shrubs that do well in our area and provide fall color include Easterm redbud, Chinese flame tree (Koelreuteria bipinnate), ginkgo, Idaho locust, Chinese pistache, crape myrtle, witch hazel, all maples, liquidambar, katsura, dogwood, locust, cherry, crabapple, oakleaf hydrangea, barberry and smoke tree.

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.
