Ruscus aculeatusButcher’s broom, also known by many other common names including knee holly, is a low growing broadleaf evergreen shrub native to the Mediterranean and western Europe. The thick, glossy, dark green structures that appear to be leaves are actually modified stems called cladophylls. They have spines on their tips and bear the flowers and fruits. The true leaves are microscopic. Tiny, greenish-white male and female flowers are usually produced singly or in pairs on separate plants in spring and female flowers produce attractive waxy red berries in late summer and fall. Flowers containing both male and female parts are sometimes produced but if berries are wanted both male and female plants should be planted. Butcher’s broom is tolerant of a variety of soils, is drought tolerant, and does well in part to full shade. It is an excellent choice for a wooded area and makes an attractive hedge. In the florist trade the greens are known as Italian Ruscus and are extensively used in wedding work.
