Purple Tree Collards are a wonderful, perennial collard with beautiful purple coloration on the stems and older growth on the plant. Cool weather intensifies the sweetness and the purple color intensity of the leaves. They remain productive year round for MANY years. Purple Tree Collards rarely bloom which means it is much more productive through the spring than some other tree collards.
Purple Tree Collards grow between 3 and 15 feet in height depending on whether you stake the plant or not. They can grow with a single trunk more vertically or with topping the plant, can branch into a large shrub form. Within the first year or two, it forms a 1/2 inch diameter trunk. It is one of the faster growing tree collard varieties.
In most cases, one can expect the Purple Tree Collards to be perennial in zones 8-11, and probably marginal in zones 7A and 7B. However, those in cooler climates are sometimes successful in overwintering them in greenhouses, etc.
Tree collards (Brassica oleracea var. acephala) are members of the brassica family. They are also known as Tree Kale or Tree Cabbage. Their relatives include traditional collards, kale, broccoli, cabbage, brussels sprouts, kohlrabi, and cauliflower. However, unlike most of its relatives, tree collards are perennial. This means that, like a fruit tree or rose bush, they will continue to grow and produce year after year and without the need for planting new seeds or seedlings every year like traditional collards and kale. Tree collards are hardy to about 20° F (-7° c) and in mild climates have been known to live for up to twenty years! They are closely related to other perennial collard varieties grown in Mediterranean, Africa, the Americas, and other countries.
