What Works in your Garden?

I’m vacationing next week in southern Mexico traveling east from the state of Chiapas to the Yucatan peninsula.  In addition to exploring ruins, waterfalls, cenotes and flamingo breeding grounds  I’ll be especially interested in the local plants which vary from  hardwood forests of mahogany and cedar to tropical.  I always study how people landscape around their own homes whenever I travel.  You can get some great ideas this way.  I’ll be sharing all that I discover in next week’s column. 

Around here this is a good time to pull plants that have been struggling now that we’ve had some rain to soften the soil a bit. Pay careful attention to and which aren’t. Be realistic about plants that don’t suit the conditions you have to offer. Replace them with plants that have proven themselves adaptable and well suited to your own garden. Thoughtful editing and repetition are the key to a successful garden.  Such self-sufficient plants require far less work, water, fertilizer and pruning.

Your own personal palette of good plants for your yard are the ones that look most at home planted right where they are. They do best in the soil, sun, wind and weather your garden offers and the maintenance is a snap. These plants don’t have to be the kind of dull and monotonous shrubs that you see around some freeway ramps. They might be the shade-loving native Western swordfern for year round interest.  Planted in masses these ferns aren’t water hogs and look like nature planted them.  Or how about the easy-peasy bergenia cordifolia which will be blooming soon planted as groundcover under the trees? Large, heart shaped leaves grow to 12 across and turn beautiful bronze color in the fall. Pink to rose-red flowers on red stalks appear in late winter.

Camellia sasanqua, with glossy evergeen leaves and showy flowers in fall and winter, can be grown as a shrub or espaliered against a wall. Camellias are easy to grow and an established shrub requires only a deep watering every 10 days or so in the growing season.

Elfin thyme is the perfect groundcover between cracks in pavers paths or other areas that get light foot traffic. And if you want any planting to look better, just pop in a black mondo grass and you’ll have instant sophistication.  Not all "go-to" plants are quite so glamorous, though. Modest, fuzzy little lamb’s ears are high on my list because they grow happily in sun or shade and any kind of soil. Stachys byzantina ‘Silver Carpet’ grows only 12" tall, blooms with purple flowers and spreads to make a beautiful edging or low border

The key to preserving both our backs and the earth’s resources is to choose the right plant for the right place. Keep the plants that are thriving and replace the unhappy plants with a smaller palette of plants that have proven themselves successful in your own garden. Whether these are California natives or plants from other regions that perform well, you’ll be happy you got rid of the malingerers.

New Plants for 2011

I know this gardening season isn’t over yet, but I’m already . Some are already being grown on a limited basis by the wholesale growers while others won’t become available until 2011. Recently I had the opportunity to view up-close and personal some of these new unique perennials, shrubs and grasses. It’s exciting to envision these in our own gardens.

It’s no secret our weather is just about perfect here. That’s why so many of the wholesale nurseries have operations in this county. They know the growing conditions are excellent here for annuals, perennials, grasses and woody ornamentals.

Many of the plants we buy start life as small plugs and liners. Some of these are produced in tissue culture labs located in places such as India, China, Guatemala and Holland. These are then grown on to sellable size by other wholesale growers before they eventually arrive at your local nursery. If you have a Black Mondo or carex grass or a cordyline, hellebore or heuchera it may have been started from a tissue culture somewhere on another continent and has more frequent flyer miles than you do.

Plant tissue culture consists of taking a piece of a plant, such as a stem tip, and placing it in a sterile ( usually gel-based ) nutrient medium where it multiplies, It’s similar to taking a cutting of your favorite houseplant and growing it to share with a friend. The production of plants in sterile containers allows the propagator to reduce the chance of transmitting diseases, pests and pathogens.

One of the new plants that I saw that really caught my eye is the grass,  Pennisetum Fireworks. The variegated pink striped blades of this grass are just as spectacular as the pink flower heads. Some gardens with clay soil and heavy frost in winter may need to grow this plant in a container but it’s worth babying this one, it’s so beautiful.

You may have bought a bright orange Begonia Bonfire this year and were impressed with the hundreds of flowers that it easily produced over the season. Well, next year you’ll be seeing the Sparkle series begonia which is similar. This tuberous begonia is nothing like the classic you are familiar with.  One plant will grow to about 24" in the ground or a container and depending on which color you choose, will be covered with scarlet, white blush, rose or apricot flowers.

And don’t even get me started on all the new mimulus colors that are going to be available next year. The Jellybean series comes in classic orange and gold but also red, purple, pink, light pink, lemon and terra cotta. Remember these are deer resistant, too.

Also there are new hummingbird favorite agastache flavors out now.  Picture in your garden, flower spikes in colors that look like fruit- grapefruit, apricot, grape and orange nectar.

I haven’t even touched on new introductions like Green Jewel echinacea or dwarf butterfly bushes in magenta, violet or pink. How about a bush form of the vine, HardenbergiaMeena will grow 36" tall and have purple flowers in winter.

Look for one of these new perennials next year. It’s going to be a colorful year in the garden.
 

Fall Tips for Gardeners

Halloween is just around the corner and besides deciding what your 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 .

 Although our nights are still well 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.

If you want to decorate for Halloween there is a lot 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.

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.

This October has had the perfect weather  allowing fall color to develop in our trees, shrubs and perennials.  Warm days, cool nights, not a lot of wind or heavy rain all help plants to attain and keep those bright reds, oranges and yellow colors we love. Here’s a short list of small plants that you can easily find space for even in the smaller garden.

Japanese barberry turn yellow, orange or red. They get red berries and are deer resistant.
Blueberries not only are good for you and their foliage turns beautiful yellow-orange in the fall.
Oakleaf hydrangea leaves take on burgundy hues.
Crape myrtle shrubs explode with brilliant red and orange color.
Pomegranate bushes turn bright yellow
Spirea foliage varies from red, orange to yellow.

Squirrel wars
If you are at odds like me with squirrels that dig up everything while burying acorns for the winter, delay planting your bulbs until Thanksgiving when they’ve finished stocking the pantry.  Store you bulbs in the frig or a cool place until then.  If you just have to plant some on a beautiful autumn day, cover the area with flat stones or chicken wire.

Don’t prune now
One last thing and you’ll be happy to hear this.   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.
