The species are dioecious, that is, individual plants of a species are either male or female. Cycads vary in size from having trunks only a few centimeters ...
Cycads all over the world are in decline, with four species on the brink of extinction and seven species have fewer than 100 plants left in the wild. [2] 23,420 species of vascular plant have been recorded in South Africa, making it the sixth most species-rich country in the world and the most species-rich country on the African continent.

A specimen of L. hopei is known as the tallest living cycad at 17.5 m tall. These cycads are generally unbranched, tall, and with persistent leaf bases. They are easily cultivated as ornamental plants and are relatively cold hardy; L. peroffskyana was first described by a specimen grown at Saint Petersburg Botanical Garden in 1857.
Including the leaves, the whole plant typically grows to 1.3 m tall with a width of about 2 m. Leaflets. The leaves radiate from the center of the trunk; each leaf is 50–150 cm long with a petiole 15–30 cm long, and 6-12 pairs of extremely stiff, pubescent (fuzzy) green leaflets. These leaflets grow 8–20 cm long and 3–5 cm wide.
While there are more than 200 species of cycads, only one is native to Florida, and only a couple are popular landscaping plants in our area.
Leaf detail. Lepidozamia peroffskyana is slow-growing, low maintenance, long-lived cycad that makes a good feature plant in semi-shaded positions or in a container. It grows up to seven metres tall but more usually reaches about four metres.
