It thrives in full sun with low water needs. It is not tolerant of much frost and should only be considered hardy to 30 -32 degrees F. We nearly lost this plant in a cold snap in November when temperatures dipped a couple degrees below freezing and "melted" this cycad's new leaves which had emerged in October. It is very closely related to Encephalartos natalensis but we have found this species to be hardier.

The native habitat of Encephalartos senticosus is open rocky areas of the Eastern Cape Province, South Africa. The name for the genus comes from Greek words 'en' meaning "within", 'kephali' meaning "head" and 'artos' meaning "bread" or "bread in head" which is a reference to the use of the starchy substance in the trunks of some species in times of desperation by African native tribes with the specific epithet meaning "spiny" and refers to the plant's leaves.

The name Encephalartos lebomboensis has long been applied to this plant but that species was split up in 1996. Most plants in cultivation under the name Encephalartos lebomboensis are actually Encephalartos senticosus. The true Encephalartos lebomboensis grows to the west of the range of Encephalartos senticosus (still within the Lebombo mountain range). It is a smaller plant with narrower leaflets. 

The information displayed on this page about Encephalartos senticosus is based on our research conducted about this plant from books in our nursery library as well as from information that is provided by reliable online resources. We also have included our own observations made about it as it grew in the nursery gardens and other gardens visited, as well how the crops of this plant performed in the containers when we had them in our nursery field. We also include comments received from others and welcome hearing from anyone who has information about this plant, particularly if it includes cultural information aiding others to better grow it.
