Fall Blooming Plants

Just because the sun goes down early now, don’t put your garden to sleep yet. Make sure you have as well as fiery foliage to perk up the view outside your windows.

Some of my favorite shrubs for the fall garden have orange flowers. If you have a spot at the back of the garden for a showy 4-6 ft shrub that requires little or no water, add a Lion’s Tail and enjoy whorls of tubular, 2" deep orange flowers that bloom from summer right through fall.

For a shorter orange-flowering shrub, consider a dwarf pomegranate. This ornamental reached 3 ft high and 6 ft wide. Blooming when only a foot tall or less, their showy orange-red single flowers are followed by small, dry red fruit that is also decorative. You can use this little shrub in borders, edging or even containers. When established in the ground they require only moderate watering.

The vibrant orange flowers of these shrubs absolutely glow when planted near purple flowers. Blooming now are Purple Pastel salvia greggii. Also called Autumn Sage, this evergreen shrub typically grows 3-4 ft high and as wide. Remember to shorten and shape plants before new growth begins in spring o keep tidy. Hummingbirds love salvias as do bees so planting them near the vegetable garden can help increase your harvest.

A groundcover for sun or partial shade that is striking in early to late autumn is dwarf plumbago. At this time of year the intense, dark blue flower clusters contrast with its red fall foliage. This 6-12" high groundcover tolerates inconsistent watering and is good for growing under oak trees.

Another drought tolerant groundcover blooming now is Huntington Carpet rosemary. Unlike some of the older varieties of creeping rosemary, this one spreads quickly yet maintains a dense center. Growing to 18" high it’s covered with pale blue flowers through the winter and into next spring. Good drainage is essential for rosemary. Lighten dense soil with plenty of organic matter. Heavy feeding and too much water result in leggy growth.  Rosemary responds to frequent pinching.  Prune older plants frequently but lightly. Don’t cut into bare wood.

This last fall blooming show stopping combination is not orange but red, purple and white. You may have Mexican bush sage, Hot Lips salvia greggii and Santa Barbara daisy in your garden already. They are popular, easy-to-grow, low water use plants. Combine them and step back.  You’ll love the way the white of the daisy brings out the intense red and purple hues of the other two.  This vignette really pops.

If you garden cries out for more fall flowers consider adding some of these plants to your garden.

Fall Gardening Tips

Someone asked me the other day  " What’s good to plant this time of year "?  It’s a good question.  I often receive emails asking for advice or ideas for solving all sorts of gardening problems and landscaping situations.  You may be wondering about some of these yourself.  Hopefully, they will solve your problem, too.

What is good to plant at this time of year ?
Fall is a good time to plant just about anything in this area. If you want an ornamental tree with spring flowers or a shade tree to keep the house cool in the summer, now is the time to plant.  The ground is moist now so digging is much easier and the warm soil will encourage root growth.  Shrubs of all types as well as perennials settle in nicely when planted in October and November.  Don’t have color in your garden from fall foliage like you see in other yards when driving around?  Take advantage of fall sales at local nurseries.  There are tons of plants now in fall color to choose from.

Why do trees turn colors in the fall?
The shorter days and cooler temperatures of autumn cause 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,  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 temperature, meanwhile can cause leaves to drop suddenly, denying the opportunity to enter their slow, colorful dormancy. 
 

 

When do we usually get the first frost here? 
I have kept a weather calendar since 1992 and based on my records there was a light frost on Oct. 29, 2002.  I’ve seen an early hard frost as early as November 7th but more commonly, frost comes later in November.   In "97-’99 frost didn’t occur until the first week of December.  Be prepared.

How long can I leave my houseplants outside? 
Halloween is a good time to bring them in.  We don’t have the heater on full blast usually this early so they don’t suffer  shock going from a cold environment to a heated one.  Be sure to inspect them for insect pests and wash them off before bringing them inside. I have to confess, I roll the dice and leave spider plants, wandering jew, Hawaiian shefflera and creeping charleys outside under the overhang. I’ve been pretty lucky most winters.

Some winters my tree ferns and bananas suffer.  How can I protect them if we have a really cold spell?  
Many subtropical plants benefit from extra mulch to help them survive a hard frost.  People from the east coast know all about this.  Just be sure to take it away from the stem or trunk come spring or the mulch can cause rotting.

Fall Planting ideas

It’s always exciting for me to see the first fall colors of the season. we may not have a show like they do in the the hardwood forests of the east coast but we’re still barbequeing and they’re not. If your garden cries out for a something that you can put a table and chairs under and still have room to play, consider a red maple. Autumn Blaze maples spread to 40 ft. wide and you’ll be enjoying their brilliant orange-red fall color long into the fall season. They need an occasional deep watering like a fruit tree but little pruning.

Take advantage or fall weather to plant cool season flowers.  October is a great month to plant as the plants will have time to become established and start flowering before winter sets in. You’ll be amazed at how much color your plants will produce when you start early. Good choices for this area include iceland poppy, snapdragon, chrysanthemum paludosum, calendula, stock, pansy, viola, primrose and cyclamen.
