General Description

Bright yellow blooms cover this hybrid broom for a lovely display in spring and summer. It is a woody shrub, evergreen in mild climates, deciduous in cooler locations and somewhat short-lived. The gracefully arching, green branches bear small, simple leaves. The strongly fragrant flowers are typical of peas or beans; larger, rounded petals subtend smaller petals that form a lip or keeled beak. They are produced solitarily or in loose clusters on short stalks in the foliage. Long lasting blooms are suitable for cutting.

Broom is compact growing with a rounded to open form. It is very tolerant of any well draining soil; however alkaline conditions may cause nutrient deficiencies. Very drought tolerant, broom prefers regular applications of water in the growing season. This is a species that does not transplant well. Plant carefully from containers when young to minimize transplanting trauma. Grow broom in containers where not hardy and in shrubbery boarders, rock gardens and beds in mild climates.
