Great Design Plant: Conebush
Sporting vivid shades of foliage, this drought-tolerant shrub fills a garden background or a vase with equal aplomb

A background plant is anything but a filler. It's a base, providing structure, highlighting surrounding plants and showcasing a little bit of its own special traits. In the garden and as a cut flower, conebush stands out as one of my favorite base plants. A South African native and member of the family Proteaceae, conebush offers dramatic foliage color year-round. Vivid shades of green, gold, red, pink and orange punctuate the garden throughout the year, adding extra holiday cheer throughout fall and winter.

Distinguishing traits. Conebush's distinguishing attributes ring true in the garden as well as in the home. Hybrids are commonplace and come in a wide variety of sizes and colors. Some varieties are shrubbier, while others resemble small trees.
Evergreen, simple leathery leaves in a wide range of hues produce inflorescence (flower clusters) primarily in fall through spring.

Leucadendron is dioecious, meaning male and female plants are distinct. Female and male floral bracts vary, but foliage and flowers are stunning on both.

How to use it. Conebush is a sophisticated choice for the temperate landscape. Its foliage complements many other plants, and it is commonly used as a background plant.
Its particular growing requirements dictate where your conebush will thrive. Landscape designer Eileen Kelly says that planting conebush on hillsides or slopes aids drainage and also showcases the depth of its foliage. Smaller plants can also be grown in containers. (Keep in mind that conebush does not transplant well.)

Planting notes. Leucadendron is sun loving, drought tolerant and an overall lovely shrub. It can be finicky about conditions and is not the easiest plant to grow. Protect it from intense winds. Promote good air circulation. Maintain well-drained soil. “I like to add perlite or small red lava rock to help with drainage,” says Kelly.
It is also particular about soil types. “Calcium and phosphorus can be detrimental to Leucadendrons, so they should not be fertilized. Adding compost annually around the base provides beneficial nutrients,” says Kelly. Compost is key.

Every spring, before new growth emerges, prune spent flowers to clean the plant up and promote more flowering. Conebush does not like soil disturbance or being transplanted, so you need to trim only spent flowers — don't cut back the entire stem.

I really like these plants , I've seen them in a few gardens in Northern California , but I have not been able to find them for sale anywhere , does anyone know where I might be a to purchase these plants , Thanks Roger
Roger, I've seen several varieties of Luecadendron plants in many nurseries in my area, just north of San Francisco. I don't know where you are located, but I'd say best advise is to call around to your local nurseries and inquire. Most nurseries can also special order plants for you. I hope you are able to find some! Eileen
