Terra Sole Nursery Trials New Plants

Have you ever wondered what it would be like to start your own little nursery on your property? What would you grow? How would you decide?  Over the years, I've been asked by home owners with a bit of extra property what would be good to grow. What is there a market for? So I decided to ask some friends who trial plants on their Watsonville property and operate a small nursery there how it all works.

Terra Sole Nurseries was founded in 2004 by John and Sherry Hall with the goal of experimenting and growing native, unusual and drought tolerant plants that are adapted to our dry summer climate. "We push the limits on water use in our test garden until we fall too much in love with a plant and can't bear to see it die with our tough love approach", Sherry said as we talked about the their operation.

Just back from attending the California Spring Trials,  Sherry and John were excited to share how they decide what to grow In their nursery. Their focus is to grow a large variety of native and unusual plants, some of which are old-fashioned, some are hot new introductions. What treasures did they find this year?

During the course of a week at the Spring Trials,  the world's prominent plant breeders, propagation specialists, growers, marketing professionals and plant enthusiasts share the latest and greatest at several open houses throughout California. The robust plant varieties of today are a direct result of the countless hours and decades of study from the dedicated professionals spending their time observing, testing and experimenting the new varieties that are more disease resistant, more floriferous, the best performers and are easy to grow in ordinary landscapes and gardens.  

How does a plant get from an idea in a breeder's mind to your local nursery? It all starts with the breeders who might cross pollinate thousands of plants to select maybe a hundred of the best ones. Then the growers buy an unrooted cutting or the seed or plugs of rooted plants and grow them onto a larger size. This is where the finish growers buy the plugs and liners to put into bigger pots growing them to retail or sellable size. Terra Sole Nurseries bought some of the newest plants on the market this year themselves.

What are some of the newest trends that we might see in our neighborhood nursery this year? The breeders of impatiens have developed a variety that appears to have a gingerbread man in the center. Called Patchwork this  impatien has a bigger flower and comes in six bi-colors.

Grafted vegetables, higher in antioxidants, are being developed. Non GMO vegetable varieties are grafted onto vigorous rootstalks to produce a plant disease resistant higher in nutrients. Tomatoes, basil, cucumbers. peppers and lettuce are just some of the vegetables being grown.

Biodegradable pots made from wheat are another of the new trends being offered for sale at the Spring Trials. The pots look like plastic yet breakdown after being used and can be recycled in your compost system. They hold up to the normal environmental pressures of heat, water and cold.

Sunset Western Gardening and HGTV are both offering their own branded plants that are available this year. Patented varieties coming out include a compact hardenbergia called Meena, two upright. compact nandinas- Flirt and Obsessive with bright red winter color and a compact mahonia called Soft Caress with non-prickly foliage. A cold hardy salvia named Amistad that has a very long bloom time will also be coming out soon.

To simplify choices for gardeners, better dahlias, calibrachoa, petunias and pansies are coming on the market this season. Several types are grown in the same pot so the buyer need only to plant one of these in a basket or container to get a combination that will look good and grow happily all season.

With so many plant choices which ones do Terra Sole Nurseries trial in their own garden and grow in their nursery? Next week I'll talk about what Sherry and John have their eye on, which plants they grow and the results of their own plant trials.

San Francisco Flower & Garden Show 2012

Every year after attending the San Francisco Flower & Garden Show I'm exhilarated by the creativity of the display gardens  and the fresh use of familiar plants. Don't even get me started on the new plant introductions I want to use in my next landscape design. This year the world-class show celebrated its 25th anniversary.

A Flower and Garden Show is a huge and complex production. Creating the 20 display gardens is a demanding task and planning for them begins many months before the show opens. By the night before the show opens 1,200 cubic yards of sawdust and mulch ( that's about 150 dump truck loads ) have been spread and 280,000 pounds of rock stacked in undulating walls and water features.

The flowers and plants for the garden come from all up and down the West Coast. Many plants are forced into early bloom for the show as Mother Nature doesn't always cooperate. Even flowering trees are sometimes kept in greenhouses so that their buds can be timed to open the week of the show. It's not a perfect science. One display garden creator who garnered 5 awards told me that hundreds of daffodils she had planned to use in her garden bloomed a week early due to warm weather. 

This year the theme of the show was "Gardens for a Green Earth". There were tips for edible gardening at home including containers for herbs and veggies on the patio and small space gardening, too. One of my favorite gardens combined tomato and flowering vines cascading over the edge of a stone vaneer wall.  Raised vegetable boxes bordered the deck for easy access and a stone water fall splashed into a huge half oak barrel.

Another interesting garden was the Low Impact Bay Friendly Garden. Modern in design, this low water-use garden featured tall raised beds surrounding a pervious concrete stepping stone patio set in a gravel base. Pervious concrete is said to be able to take in storm water a a rapid rate of over 5 gallons per minute per square foot of surface area. That far exceeds the flow rate needed to prevent runoff in even the most severe rain events.
The rainwater is temporarily stored in the course gravel layer underneath while it is allowed to naturally percolate into the underlying soil. This could be a good solution to solve site drainage problems.

Most of the display gardens featured water in them. Some were large affairs with cascading boulders while others were small and understated. In one, a length of copper tubing delivered a shower of drops in front of an aged corrugated iron panel. Another consisted of a simple stacked flagstone ledger waterfall flowing into a flagstone pond- a DIY project?  Even used tires were used as the base for the flagstone edging around a pond although frankly, I couldn't picture this water feature in anybody's backyard. One I did like was a simple flume of water pouring into a small metal rectangle lined with Mexican black pebbles. A little feature with lots of impact.

Fire pits were prevalent, too. From ornate fireplaces to glass filled affairs to simple metal rounds filled with cobbles outdoor living is enhanced with fire and water.

I had to laugh when a man asked me at one of the gardens what I was taking a picture of.  Well, I explained, I take photos of paths and steps and how they're put together and the materials they're made of for future reference. "Oh, that's a good idea" he said, and started taking pictures, too. All in a day at the San Francisco Flower and Garden Show.

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.
