Originally from Japan, where it grows under the tree canopy, it has a brownish pineapple-shaped stem from which projects a loose rosette of feathery fronds up to 31t/90cm long. Each evergreen frond has a stiff central rib, from which emerge many closely packed 3-6-in/8-15-cm-long needlelike leaflets, arranged in a chevron pattern. Some of the inner fronds are almost vertical, but most arch gracefully; the plant produces only one new set of leaves a year. Both male and female specimens are needed for cycas to produce its large red seeds, but they are not very likely to flower in pots, and if they do, must be hand-pollinated. FACT FILE
