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 ...
Mature plants have big stems of between 0.5–1 m (20–39 in) in length and 20–30 cm (8–12 in) in diameter [6] with the majority of the stem growing below ground. [4] Leaves are up to 1 m (39 in) long and often sharply recurved towards the tip, looking stiff and spiny. [5] Younger leaves are a silvery-blue colour but turn green with age. [6]
This is a tall, tree-like cycad plant with a stem that can be upright or lying down, reaching up to 4.5 m (15 ft) in height and 30 and 45 cm (12–18 in) in diameter. Its bright green, feather-like leaves grow in a cluster at the top of the trunk, each leaf being 1–1.5 m (3.3–4.9 ft) long and supported by a 10–20 cm (4–8 in) long stalk ...
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.
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.
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.
Cycads are dioecious, meaning that there are separate male and female plants, and the female produces seeds while the male produces pollen. Plants of this taxon have generally been considered to be wind pollinated, but several recent studies suggest that insect pollination is more likely. The seeds produced are typically large with a hard ...
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.
