Cycads in South Africa. Cycads / ˈ s aɪ k æ d z / are seed plants that typically have a stout and woody trunk with a crown of large, hard, stiff, evergreen and (usually) pinnate leaves. 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 are long-lived and slow-growing, with slow recruitment and population turnover. [9] All cycads possess 'coralloid' (meaning coral-like) roots. These roots contain symbiotic cyanobacteria that fix gaseous nitrogen from the atmosphere and provide essential nitrogenous compounds to the plant. This can be a great advantage, as many cycads ...
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.
The leaves are pinnately compound and can grow up to two meters long. They are typically hard-textured, and green. [7] Young leaves are described as being hairy, and ranging from dark green to coppery brown in color. [4] Each leaflet is about 15 cm long and about 3.5 to 5 cm wide.
The plant can survive up to USDA region 8b (10° to 20°F). The stems and leaves regenerate after the cold period subsides with full foliage. [8] [9] Like other cycads, Z. integrifolia is dioecious, having male or female plants. The male cones are cylindrical, growing to 5–16 cm long; they are often clustered.
Encephalartos lehmannii is a low-growing palm-like cycad in the family Zamiaceae.It is commonly known as the Karoo cycad and is endemic to South Africa. [3] The species name lehmannii commemorates Prof J.G.C. Lehmann, a German botanist who studied the cycads and published a book on them in 1834. [3]
The Fix: If the leaves are falling over because of root rot or the plant is root-bound, repotting it is the best solution. "Snake plants should be repotted every three or four years," says Langelo.
The leaves are a deep semiglossy green and about 50–150 cm (20–59 in) long when the plants are of a reproductive age. They grow out into a feather-like rosette to 1 m (3.3 ft) in diameter. The crowded, stiff, narrow leaflets are 8–18 cm (3.1–7.1 in) long and have strongly recurved or revolute edges.
