Plant in full sun in a well-drained soil. Irrigate only occasionally. This old cultivar has been growing at the Huntington Botanic Gardens since around 1929 and so has persisted through the coldest of winters there and likely hardy down at least to short duration temperatures of 20° F. This should prove to be a great aloe for mass planting with its attractive low rosettes and tall showy winter and spring flowers.

Aloe 'William Hertrich' has long been growing at the Huntington Botanic Garden and is a hybrid that long time garden manager William Hertrich (1878-1966) created, possibly involving Aloe burgersfortensis, a maculate aloe from Burgersfort in the Mpumalanga Province of South Africa. For years it resided in Desert Garden Bed 16 simply as Aloe HBG 16446 but it performed so well that the late Gary Lyons, the former Curator of the Desert Garden at the Huntington, named it after Aloe 'William Hertrich'. In 2018 micropropagated (tissue cultured) plants were released in the Huntington's International Succulent Introduction program as Aloe 'William Hertrich' Lyons ISI 2018-14 and in 2019 we were fortunate to get plants from the Huntington to grow on. 

This information about Aloe 'William Hertrich' displayed is based on research conducted in our horticultural library and from reliable online resources. We also will relate observations made about it as it grows in our nursery gardens and other gardens we have visited, as well how the crops have performed in containers in our nursery field. We will also incorporate comments that we receive from others and we welcome hearing from anyone with additional information, particularly if they can share any cultural information that would aid others in growing it.
