When the plant matures it can produce red-purple buds and greenish flowers on a 10 foot spike. Plant in full sun, except in hotter inland gardens where light shade or morning sun is best, in a well-drained soil with occasional irrigation in late spring and summer. Hardy to around 15°F. This plant has been in Agave collections for years as Agave filifera 'Compacta Marginata'. Tony Avent of Plant Delights Nursery provided the cultivar name 'Shira ito no Ohi' and the literal translation from Japanese for the common name of "Queen of White Thread-leaf" - with 'Shira-ito' meaning "white-thread" and 'no ohi' (or 'no oji') meaning "queen". Since we received this plant as an Agave schidigera cultivar we list it this way but note that Howard Scott Gentry was skeptical of Agave schidigera being a valid species when he wrote about it in his “Agaves of Continental North America” and in recent treatments by Bernd Ullrich and Joachim Thiede it has been reduced to subspecies status under Agave filifera from which it differs by being solitary, typically having longer more flexible leaves that are not thickened toward the base and larger flowers. Agave filifera ssp. schidigera is found in the wild from Chihuahua south to Michoacán and east to San Luis Pososí, Zacatecas and Durango. The origin of this cultivar is as yet unknown.  This description is based on our research and observations made of this plant as it grows in our nursery, in the nursery garden and in other gardens that we have visited. We will also incorporate comments received from others and always appreciate getting feedback of any kind from those who have some additional information about this plant, in particular if this information is contrary to what we have written or if they have additional cultural tips that would aid others in growing Agave schidigera 'Shira ito no Ohi'.     [MORE INFO]
