Plant Common Name

Alphonse Karr Bamboo, Clumping Bamboo, Hedge Bamboo

General Description

The Alphonse Karr bamboo is a clumping bamboo native to China. All bamboos are grasses with woody-type stems called culms which are divided into sections and branched. Hedge bamboo selection ‘Alphonso-Karrii’ has slender, arching culms which are smooth with no teeth or spines. The culms emerge with a pink tint and mature to a rich gold, striped with deep green. Bright light also brings out pink at the culm joints or nodes. The leaves are linear to lance-shaped and produced in pairs, many pairs are crowded on the branches. Bamboo flowering is unusual, the flowers are similar to other grasses and the fruits grain-like, but the conditions and age of the plant for flowering is not completely understood. Flowering seems to occur between 2 and 7 years of age and many bamboos decline and some die after flowering.

Shrub bamboo is a tropical grass, prefers moist well-drained soil and full sun. Alphonse-Karr bamboo is somewhat cold hardy and will endure winter temperatures down to the range of 10 to 20 degrees Fahrenheit. The spread of shrub bamboo is slow, the rhizomes or underground stems grow only a short distance from the clump before rapidly sending up new culms in summer. Shrub bamboos are great plants for containers, indoors or out, and visual property screens.
