Ruscus hypoglossum

Ruscus hypoglossum, a native of Western Europe to Iran, is a compact evergreen shrub with a creeping rootstock that will reach 18 inches tall. It is an interesting plant with leaf-like cladodes (also known as phylloclades) to 3 inches wide to 1½ inches wide tapering at both ends. The true leaves are the smaller green appendages around the flowers. The "phylloclade" is a leaf-like flattened stem! (The giveaway is to look at the venation, which is much more stem-like).

Blooming Time: In spring, the very small flowers are produce in the axil of the leaf-like bract on the top of the cladode.

Culture: Ruscus hypoglossum need partial shade to full shade. Even though they tolerate full sun, the color is richer in shade. We grow ours under 70% shade all year. A suitable soil mix consists of 1 part peat moss to 3 parts loam to 1 part sand or perlite. They are very drought tolerant, but should be watered twice a week for optimum growth. Plants are fertilized once during the growing season with a balanced fertilizer. For folks with a warmer winter temperature (zone 8-10) they make outstanding groundcover under trees where nothing else will grow.

Propagation: Ruscus hypoglossum are propagated by division or by seed. Seeds need to be treated with gibberelic acid for 48 hours before sowing. Seeds are sown ¼ inch deep and should germinate in 60 to 120 days at 70° F.

Ruscus hypoglossum was featured as Plant of the Week February 1-7, 2002.
