Agave salmiana 'Green Giant' (Giant Agave) - This architectural succulent is recognizable by its thick, graceful, dark gray-green out-curving leaves with projecting spines and massive stature, reaching to 5-6 feet tall by twice as wide. When the plant matures and blooms the tall candelabra inflorescence rises to over 20 feet bearing yellow flowers that attract birds and bees. Produces ample suckers which can lead to a large colony if suckers are not removed. Plant in full sun where it is drought tolerant. In southern California this large dark green plant has long been identified as Agave salmiana var. ferox but recently, in consensus with several Agave experts in Texas, it now appears that this plant is actually a nice form of Agave salmiana; the variety ferox should be a much smaller plant and we currently grow a selection of it called 'Green Goblin'. Howard Gentry noted in his book that this plant is sensitive to frosts. We have had it weather through nights that dropped to 18 F without damage. The origins of this variety are somewhat unknown. It differs from other Agave salmiana in its massive stature, urceolate form and the shiny green leaves with short acuminate leaf tips. It was noted in cultivation in the Tehuacan and Puebla regions, probably because Agave salmiana is considered to be the great wine making agave "maguey de pulque" and was long cultivated for this purpose. This plant has also been in cultivation in Europe since the 19th century. A real specimen agave; not for the timid but a really distinct looking plant! Use extreme care when working around or trimming any Agave. Not only are the spines wicked and cause a painful swelling if one is poked, but the sap of many species is caustic. Many a person has regretted using a chainsaw, which throws the juices back at the user, to trim an agave.  The information on this page is based on our research that has been conducted in our nursery library and from online sources as well as from observations made of this plant as it grows in the nursery, in the nursery's garden, and in other gardens where it has been observed. We also incorporate comments received from others and always appreciate getting feedback of any kind from those who have additional information, particularly if this information is contrary to what we have written or includes additional cultural tips that might aid others in growing  Agave salmiana 'Green Giant'.
