Gardeners' Notes:

Ive had this plant in the ground for several years in the south-East part of my garden. It is blasted with full Las Vegas sun and heat year-round, and it has grown to be quite big. It is about 3.5 feet tall and 4 feet around. It blooms profusely in the spring, and attracts lots of bees. It also serves as a way station for small birds that take shelter in the branches.

Many landscape companies prune these poor shrubs with hedge trimmers, making them look like cupcakes, which I suppose is a lame attempt at topiary, but it makes these shrubs look dreadful. I prefer their natural shape with a prune here and there.

This plant is great for hot, dry areas.

A sturdy plant that grows quickly and takes the desert heat well. It looks so graceful and delicate but maintains excellent health with little fuss. This spring it was covered with yellow flowers, and although yellow is not my favorite flower color, the aroma was very pleasant. We like these so much we put in three more!

I adore this plant, so delicate looking yet so low maintenance. Mine in planted in amended clay soil, receiving afternoon sun. I would describe it as a slow grower. Highly recommend.

An evergreen shrub from Australia.

Has silvery-green, pinnate leaves with linear leaflets that are covered in grey hair. Bears yellow, pea like, scented flowers. Pods are light brown and slender when ripe.

Flowers at various times all through the year if grown indoors.

Loves a well drained soil in sun. It needs a sheltered position as it can be easily damaged by frosts, especially when young.
