Description

Encephalartos altensteinii, commonly called prickly cycad, is a very slow-growing, evergreen tree with palm-like foliage that is native to South Africa (East Cape Province). In the early years, this tree appears trunkless, producing stiff, pinnate, palm-like leaves with spiny bright green leaflets. Leaves are whorled into a dense upright crown. Over time, a stout trunk begins to develop, eventually rising to 12-16’ tall. Trunks often tend to recline once they reach about 10’ tall. On mature trees, leaves in the terminal crown will grow to as much as 9’ long. This is a dioecious tree that reproduces by seed cones. Large yellowish-green cones on female trees grow to 22” long, somewhat resembling a pineapple. Cones on male trees are cylindrical and smaller. Leaflets usually have prickles, hence the common name of prickly cycad. Another common name for this tree is bread tree. Winter hardy to USDA Zones 10-12 where it can be grown outdoors in medium moisture, well-drained loams in full sun to part shade. Tolerates shade. Best performance occurs in moist soils with regular irrigation, but avoid overwatering. Tolerates drought. Also tolerates occasional light frost. Ornamental specimen for frost free areas. Grow in conservatories, warm greenhouses or as indoor potted plants north of USDA Zone 10. Excellent trunkless indoor container plant when young.
