Ruscus aculeatus is a slow-growing evergreen shrub, with a low growing habit. Its dark green spiny leaves (which are actually flattened stems) are lanceolate with entire margins, up to 2.5cm long and 1cm wide. At the center of this ‘leaf’ a small dark green appendage is present, this is the true leaf. Its small green and purple dioecious flowers appear at the true leaf axil. Its red fruit is a berry and up to 1cm across and are retained on the plant through the winter months. Its roots are rhizomes which aids its spread.
