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.
 

Landscaping Tips for Great Gardens

By this time of the year, you probably have planted some new perennials for color in your garden. But if you look around and still feel something is missing the answer may be that your landscape needs more than color. As a landscape designer I am often called upon for ideas to create richer landscapes that provide four seasons of interest. Here are some tips I pass along.

A more sophisticated appeal and enduring quality in your landscape can be achieved if foliage color is used to complement, or contrast with, other plants within the design. This technique unifies the overall look while offering appeal throughout the season. One plant that would make this happen is Rose Glow Japanese barberry. Their graceful habit with slender, arching branches makes a statement by itself but it’s the vivid marbled red and pinkish foliage that steals the show until they deepen to rose and bronze with age. In the fall, the foliage turns yellow-orange before dropping and bead-like bright red berries stud the branches fall through winter.

Abelia Confetti is another small shrub that can be used to unify your landscape. Growing only 2-3 ft high and 4-5 ft wide with leaves variegated white, their foliage turning maroon in cold weather. Abelias are adaptable plants, useful in shrub borders, near the house or as as groundcover on banks. White, bell-shaped flowers are plentiful and showy during summer and early fall.

Texture in foliage is very important in good garden design. Varying the size and shape of leaves creates diversity and variety among neighboring plants. Striking visual interest can even be achieved when working with two different plants with similar shades of green.

An example of this would be combining Gold Star pittosporum tenuifolium with grevillea noellii. The first has dark green oval foliage on 10-15 for dense plants while the latter is densely clad with narrow inch long glossy green leaves. Clusters of pink and white flowers bloom in early to late spring and are  a favorite of hummingbirds.

Using the same plant shape throughout a landscape can create and tie the entire design together. Forms and shapes of plants and trees can be columnar, conical, oval, round, pyramidal, weeping, spreading and arching. A loropetalum with its spreading tiers of arching branches could be repeated throughout your garden to create visual interest and balance. A dogwood tree could also repeat this same form as their branches grow horizontally.

Consider also layering plants to create a beautiful garden. From groundcovers all the way up to the tallest tree, natural looking designs mimic nature.

Don’t forget about focal points. This could be a Japanese maple cloaked by a wall of dark evergreens or a statue or pottery at the end of a long, narrow pathway. Focal points draw attention and even distract the eye from an unsightly view.

There are many solutions to make your garden complete. Consider using some of the above design elements to make your landscape beautiful. 

New Plants for the Garden

Every season new varieties of colorful flowering annuals and perennials are introduced by hybridizers. These new plants are field tested and bred for better performance, disease and insect resistance, flower size, color and heat tolerance.  Where does this happen?  What goes into that gorgeous vivid red geranium you see on the bench at the nursery?

Over 30 breeders of flower seeds and perennial starts each spring showcase their new varieties in trials held throughout the state.  Professional growers visit the trials to choose which new varieties they will grow this year and offer to local nurseries and garden centers.  Goldsmith Seeds in Gilroy is one of the locations that hosts the colorful spectacle.

Fragrant, wisteria-covered arbors shade paths that wind throughout the landscaped grounds . The grounds are open to the public to enjoy throughout the summer.  Also on site are the greenhouses where breeders work on creating new and better flower varieties.  It was interesting to see several acres planted with fava beans as a cover crop. Soon the fields of this flowering legume will be cut down and tilled into the soil to add nitrogen. Legumes attract soil dwelling bacteria that attach to the plant’s roots and pull atmospheric nitrogen out of the air and soil, storing it on the roots as nodules.  When the plant is cut down and chopped up to decompose that nitrogen remains in the soil to feed new plants. After a few weeks of decomposition the energized soil will be ready for planting test flowers that Goldsmith seeds will further evaluate.

All of the seeds are actually grown in greenhouses in Holland and Guatemala. Cool season flowers like primroses, cyclamen, violas and pansies are produced mainly in Holland while warm season flowers like dahlias, geraniums, gazanias, and verbenas are grown at different elevations in Guatemala. I learned Goldsmith Seeds has been developing and growing seed in Guatemala for 40 years.

What new cultivars really impressed me at the trials?  There’s a new geranium that combines the best features of ivy and zonal geraniums. I liked the amazing color of Calliope Dark Red but all the colors were show stoppers. They would be perfect for baskets or beds in full sun or part shade. And you should see all the colors that calibrachoa now comes in-light blue, dark blue, deep yellow, peach, orange, even white with rose veins. These have now been bred to bloom earlier in the season which is why you’re seeing them in nurseries now.  There were many fragrant flowers like . I always looks forward to them when they arrive at the nursery. 

Try something new in your garden this year. There are so many good choices.
