Agave gentryi (Hardy Agave) - A medium sized green Agave gentryi that forms solitary rosettes to 4 to 5 feet tall by 5 to 6 feet wide with thick and wide light green leaves armed with large teeth along the leaf margin and a long terminal spine. The leaves have strong bud imprints and fold upright on both margins. Plant in shade, especially in hotter climates, although tolerates coastal California full sun. This is one of the most cold tolerant of the large agave, tolerating temperatures down to 5° F. Water occasionally to regularly. Agave gentryi was first described by Howard Scott Gentry in Agaves of Continental North America. He described this plant as Agave macroculmis and noted that the leaves grew to 45-85 cm (18-33 inches) long by 17-26 cm (7 -10 inches) wide. In Joachim Thiede's more recent treatment of Agave in Illustrated Handbook of Succulent Plants: Monocotyledons he cites Bernd Ullrich, who had renamed and described this plant as Agave gentryi after noting the name A. macroculmis should be rejected because it was a synonym for Agave atrovirens. Thiede describes the leaf size as 60-100 cm (24 – 39 inches) long x 17-26 cm (7 -10 inches) wide. This crop from seed received in March 2012 from Brian Kemble off of a plant that flowered at the Ruth Bancroft Garden in 2010.
The information presented on this page is based on research that we have conducted about this plant in our library and from reliable online sources. We also consider observations we have made of it growing in the nursery's garden and in other gardens we have visited, as well how it performs in our nursery crops out in the field. We will incorporate comments that we receive from others as well and welcome getting feedback from anyone who may have additional information, particularly if they have knowledge of cultural information that would aid others in growing Agave gentryi. |
