The Mountain Gardener’s Hot Plant Picks for 2011

It’s not just another garden show, it’s the world renowned San Francisco Flower & Garden show and it was the perfect start to spring. Sure the show gardens are part theater and part reality but you can’t help but come away with inspiration, ideas and spring fever. One of my favorite parts is the display of new plant introductions from Western Horticultural Society. These are great plants destined to become favorites in the garden.  Well, I have my own Top 10 Hot Plants for 2011. These selections do not include California natives because Native Plant Week is coming up soon and I’ll focus on our valuable natives in an upcoming column.

I’m often asked for plant recommendations for our unique set of gardening conditions-extreme weather, heavy clay or sandy soil and limited water resources in the summer months. The following plants are easy to grow, have few or no problems with pests of diseases and posses valuable qualities such as color, fragrance, winter interest or support wildlife and beneficial insects. Try something new this year in your garden.

Grevillea lanigera ‘Coastal Gem’. This low spreading shrub grows 1 ft tall by 4-5 feet across and blooms year round with pink and white spidery flower clusters. Great for attracting nectar feeding birds and gophers don’t like their taste. Full sun, evergreen and drought tolerant -this is a great groundcover.

Kaleidescope abelia
This evergreen shrub is a kaleidescope of color as it’s name implies. Variegated foliage is bright yellow and green in spring, changing to golden yellow with bright oranges and fiery reds in fall. Its grown habit is densely compact and rounded. The beautiful foliage doesn’t scorch in the sun either.  It’s a beauty 2-3 ft tall and 3-4 feet wide. What more can you ask for?

Loropetalum Pipa’s Red
Also known as Fringe flower this shrub sports rich burgundy foliage in a fountain shape with tiered branches. Raspberry flower clusters are heaviest in the spring but some bloom is likely throughout the year.   I place this plant in the foreground where you can appreciate it’s graceful shape-looks great as an accent or in a raised bed.   The burgundy color can add color to a woodland garden and it even does well in a container on the patio.   You can prune it to any size but please don’t turn it into a tight ball and ruin it’s shape. Another plus is that it is not attractive to deer. 

Karl Foerster feather reed grass adds a vertical element to your summer and fall garden. It provides wonderful contrast among low shrubs and perennials. Named after the famous landscape architect and photographer with a love for all aspects of perennial plants, Karl Foerster  lived in Germany from 1874 to 1970. This grass won the 2001 Perennial Plant of the Year and although it’s not new on the market it’s an  easy to grow ornamental grass that won’t overpower your space.

Cordyline Electric Pink
This show stopper lives up to its high-voltage name. It surpasses other grass-like plants with boldly striped leaves of maroon and shocking pink. This well-behaved cordyline is clump-forming and reaches only 2-4 feet in height and width. Place in large mixed container or flower borders to instantly add an exciting look.

Pennisetum Fireworks
With arching leaves striped with white, green, burgundy and hot pink this grass is beautiful in the garden. Purple tassels rise above the foliage in late summer. The variegated pink striped blades of this grass are just as spectacular as the purple flower heads. Some gardens with clay soil and heavy frost in winter may need to grow this plant in a container for protection but it’s worth the extra effort.
 

Leaucadendron Safari sunset
Fiery red bracts on densely covered tall stems are sure to draw oohs and aahs. This is one of the most popular Leaucadendron available. It’s a vigorous, erect grower to over 8 feet tall and tough enough to handle frost and clay soils. The flower is actually an insignificant cone surrounded by large colorful bracts which are excellent for cut foliage harvesting.

Belinda’s Find red hook sedge
This red sedge is a two-tone delight of bright cherry red leaves with a green stripe running down the center.  Its loosely tufted, upright form grows 12" tall by 15" wide in part sun. Tiny bulrush-like flowers, from June to August,are elevated above the tidy, low growing evergreen clump. Use in the front of the border, in masses or mixed containers.

Euphorbia Diamond Frost blooms continuously with clouds of white flowers that float above finely textured apple-green foliage. This delicate looking perennial may be small in stature, reaching 12-18 " tall and wide, but is easy to grow and surprisingly tolerant of drought and heat. Combine this airy plant with bright colors for a dazzling border.

Phormium Jester is a New Zealand flax cultivar that grows to 3 feet making it a better fit in the garden than some of the larger phormiums. It can tolerate fairly dry conditions but looks best with occasional to regular irrigation. This strong color combination of green and pink doesn’t revert to the parent plants coloring. It’s hardy to 15-20 degrees. You might find this plant also listed as Jubilee.

 

Garden Tips for March

Spring is in the air. It’s always exciting to see the plants in the garden come to life. I’ve been invited to tour a  garden in Scotts Valley in April when many of the early flowering plants will be in bloom.  I’ve been to this garden before and there’s always an interesting tree, shrub or flower to enjoy.

One of my long term goals is to view the great gardens in the Santa Cruz Mountains. If you have a garden that you think others would like to hear about and you are willing to share it with me, please contact me. I’d love to spend time with you in your garden.

There’s so much to do now in the garden. If you are feeling overwhelmed here are some suggestions for the more important to-do’s.

* Check drip systems for leaks or clogged emitters. Flush sediment from filters and check screens for algae. You may need to add emitters if plants have grown significantly.

* Finish pruning and clean-up of trees, shrubs, vines and perennials. This includes fireblight die-back on pears, apples, hawthorn, pyracantha, photinia, crabapple quince and toyon., Prune out and discard diseased branches making the cut at least 6-8" below blighted tissue. Clean the pruning blades with alcohol or a 1:5 solution of household bleach to prevent spread of the disease. Also finish pruning and cutting back perennials and ornamental grasses. Go ahead and give grasses a 3-5" crewcut so fresh growth can emerge. Cut back old foliage of maiden hair ferns to allow new growth to take center stage. If you have Western sword ferns or another type that has winter or thrip damage, remove shabby looking fronds. Even if you have to cut back the entire fern it’s OK. It will regrow in just of couple of months.  Prune any other frost damaged plants when you see new growth begin.

* Spread fresh compost around all your plants. Good soil is the secret to successful gardening. The first principle of organic gardening is to feed the soil and it will feed the plant. Remember that all gardening used to be organic. Layer compost and or mulch on top of the soil and let it slowly decompose and filter down into the earth.

* As you plant new additions to the garden add organic matter to the soil. If your garden’s soil is sandy, organic matter enriches it and allows it to hold water more efficiently. If your soil tends toward clay, organic matter will loosen it up and improve drainage. In well-amended soil, plants grow deep roots, are hardier and more resistant to disease. Organic matter, such as compost, planting mix and well-rotted manure, boosts nutrition and improves soil structure.

* Fertilize if you haven’t already done so. Citrus, shrubs and fruit trees just emerging from dormancy are begging for their first meal of the season. Lawns begin their spring growth now also and benefit from a boost of nitrogen. You can also spread a thin layer of composted manure over you lawn. Leaving you grass clippings on the lawn will benefit it by shading the roots as it get warmer and as they break down they help feed it, too. Perennials benefit from both a fresh layer of compost or manure and a light application of balanced fertilizer. They respond to phosphorus especially in the spring for root growth, stem sturdiness and flower development. Wait until azaleas, camellias and rhododendron have finished blooming before feeding them.

* The most important to-do for March is to take time out and enjoy your garden and our beautiful surroundings. Those last few weeds will be there tomorrow but you’ll never get another today.

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.
