Aloe helenae - A typically non-branching small tree aloe to 13 feet tall but in cultivation it is noted that plants often branch from the base. It has 4 foot long recurved and channeled broad based olive green leaves that turn reddish in bright light and drought stress. In late winter to early spring (earliest in warmer areas) appear the multiple short unbranched inflorescences at the top of the rosette with red buds that open to pale yellow in 6-inch-long cylindrical racemes that are tightly covered with hundreds of flowers - fully open they resemble a grouping of Banksia flowers more than they do a typical aloe.

Plant in full sun in a well-drained soil and irrigate occasionally to infrequently - likely can be unirrigated once established. This plant has been in cultivation only in near frost-free gardens so until we know better we list its frost tolerance to 30 °F. It grows near the ocean in nature so likely can be planted at least in near coastal gardens. A very attractive and unusual species that is known to be easy to cultivate in gardens in mild climate areas.

Aloe helenae is endemic to the Fort Dauphin region in the extreme south-west of the Toliara Province of Madagascar, where only two or three very small populations are known to occur in thorny bush along sandy shores. It is considered Critically Endangered. The specific epithet honors Helen Decary, the wife of Raymond Decary, a French financial administrator and 20th century botanist in Madagascar. Our plants are cutting grown from plants received in 2012 from the Institute of Aloe Studies as Aloe helenae IAS 12-011c. 

The information displayed on this page about Aloe helenae 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.

 
We closed for regular business at the end of 2025 in order for the property to be developed for affordable housing.
Our gates remain closed but we will open them by appointment to interested parties as we liquidate remaining supplies and equipment.
