Yucca Linearifolia has hundreds of narrow pliant blue-green 24 to 36 inch long leaves in a globular head standing above the ground on a stout trunk that can reach to 4+ feet tall with time.
We do not know the hardiness of this plant but it has tolerated the coldest temperatures we have recently experienced (~25° F) without damage though we suspect this plant can go much colder. In fact we heard from a person in Austin Texas who told us that this plant survived after several days hovering around 12° F. It has also proven to be heat and drought tolerant.
In the past this plant has been considered a form of Y. rostrata (Y. rostata var. linaris) but recent treatment has placed it in its own species noting that its distinctive combination of fleshy fruit and narrow, linear, denticulate leaves sets it apart from all other yuccas. (Clary, Karen “Yucca linearifolia (Agavaceae): A New, Indehiscent, Fleshy-Fruited, Linear-Leaved Species Endemic to the Chihuahuan Desert, Mexico” Brittonia, Vol. 47, No. 4.) Our plants from Pat McNeal of McNeal Growers in Manchaca, Texas.
The name Yucca was given to the genus by Linnaeus, perhaps by mistake, as it is the Latinized derivation of “yuca”, the Caribbean name for Cassava (Manihot esculenta) an unrelated plant in the Euphorbia family that is native to the Caribbean area. Interestingly it was also Linnaeus who applied the name Manihot to Yuca. This description is based on our research and on the our observations of this plant as it grows in containers at our nursery and landscape plantings in our own nursery garden and other gardens that we visit.
We also will incorporate comments we receive from others and appreciate receiving feedback of any kind from those who have additional information about this plant, particularly if they disagree with what we have written or if they have additional cultural tips that would aid others in growing Yucca Linearifolia.
