Botanical PronunciationSIH-tiss-us
LoreThe brooms are shrubs actually used to make brooms or "besomes" in the Old World. While in some environments, common broom (Cytissus scoparius) can re-seed and spread to form dense stands that tend to crowd out native plants and is considered to be an invasive species in California and the Pacific Northwest, hybrid cultivars of this plant are much less aggressive and some do not produce viable seed.
Average Size at MaturityModerate growing; reaches 3 to 4 ft. tall and wide.
Bloom TimeSpring to Early Summer
Design IdeasThis is a Broom that is small enough for city gardens. Use as a substitute for non-flowering coniferous hedges along a driveway or the front lawn's edge. Or use as a single specimen for a lavish show of red and yellow bicolored flowers. Do not place larger plants too close as they may constrain its low, broad profile.
