Cycas — 17 species
Botanical species in the genus Cycas recorded in the PlantPeers database.
Cycas beddomei
Cycas beddomei
Family: Cycadaceae
Cultivation
Cycas beddomei grows in a drier part of the monsoonal tropics of southern India, where the mean annual rainfall is in the range 570 - 1,230mm, and daytime temperatures are in the range 25 - 35°c, nighttime about 20°c An almost universal requirement for cycads is a well-drained but moisture-retentive soil, and by far the best soils are sandy gravels and light loams which provide the required drainage and aeration necessary for good growth. Cycads will generally not grow well in clay soils unless those soils are heavily amended with sand and organic matter. A neutral soil (pH 7), is generally best for most species of cycads and allows the proper absorption of nutrients.

Cycas micronesica
Family: Cycadaceae
Cultivation
Cycas micronesica is a plant of tropical regions and is sensitive to frosts. An almost universal requirement for cycads is a well-drained but moisture-retentive soil, and by far the best soils are sandy gravels and light loams which provide the required drainage and aeration necessary for good growth. Cycads will generally not grow well in clay soils unless those soils are heavily amended with sand and organic matter.

Cycas nathorstii
Family: Cycadaceae
Cultivation
Cycad species are most commonly found in sub-tropical to semi-arid topical climates that are generally frost-free or only experience occasional light frosts. Although they mainly prefer a summer rainfall climate with cool, dry winters, most of them will adapt easily to a Mediterranean climate with its dry summers and moist winters Rainfall must be at least 350mm annually for cycads to survive. Some exceptional tropical habitats may have rainfall in excess of 5,500mm annually.

Cycas panzhihuaensis
Family: Cycadaceae
Cultivation
Cycas panzhihuaensis is native to the subtropical zone in southern China. It is found in an area where the maximum high temperature is just over 40°c and the minimum is aound −1°. Occasional frosts can occur over a period of about 10 weeks in the winter.

Cycas pectinata
Cycas pectinata
Family: Cycadaceae
Cultivation
A plant of tropical climates in areas with wet, humid summers and milder, drier winters. Succeeding on a variety of substrates, the plant prefers moist conditions and clay soils over limestone. An almost universal requirement for cycads is a well-drained but moisture-retentive soil, and by far the best soils are sandy gravels and light loams which provide the required drainage and aeration necessary for good growth.

Cycas siamensis
Cycas siamensis
Family: Cycadaceae
Cultivation
A plant of tropical woodlands, growing in areas that are characteristically seasonally wet and dry with the monsoon weather patterns of the region, with particularly pronounced and extended dry periods.
