Yucca treculeana var canaliculata - 1 gallon

Grand trecul yucca! After years of growing this plant, we think that we have an identity that we are comfortable with. We acquired our seedlings from wholesale grower in Arizona, labeled as Yucca carnerosana. We became suspicious of their actual identity because the plants were so robust and filifer-less. The seed’s collector was vague as to where the seed came from; originally stating that it was collected in southwest Texas. The name Y. grandiflora was temporarily applied because at a different time it was believed that the the seed was collected in Durango, Mexico. Since Yucca grandiflora and Y. treculeana are similar looking in many ways, and believing the seed came from Durango, we used the name Y. grandiflora. When our first seedlings bloomed two years ago, we changed our minds, and we have since decided we must have a more robust form of Y. treculeana. At about the same time our plants bloomed, we obtained a copy of the Missouri Botanical Garden Thirteenth Annual Report from 1902, which had a description of Y. treculeana var. canaliculata. This variety is a much larger, more robust form of Y. treculeana reported from deep Southwest Texas. Also found in this book is a photo which sure looks like our plants. We don't know if this identification will stand the test of time but for now it's our conclusion.
