- Description
-
Butcher's broom, is an evergreen shrub in the Asparagaceae (asparagus) family. The plant grows well in partial or lightly shaded sites, but will tolerate full shade, in a range of soil types, and in average well-drained soil. and can be useful as a hedge. It is hardy and tolerates drought, heat, and salt. Plants have a slowly creeping rootstock and will form large clumps. It may sucker to form colonies and you should cut away dead stems at the base of the plant in the spring. The plant is also commonly known as Knee Holly because, when mature, it reaches knee height.
Most species of Ruscus are dioecious (that is, have separate male and female plants) except for this species which sometimes has self-fertile flowers. Regardless of this trait, you should plant both sexes in a ratio of one male to six female if maximizing fruit production is desired. The flowers of this plant are insignificant, but they are followed by bright, waxy, red berries that last from late summer into the winter. The actual leaves of this shrub are very small. The glossy dark green parts of the plant that appear to be leaves are actually shoots or stems that act as a base for the flowers and berries.
