This recently discovered species from Texas and into Oklahoma was published in 1990 by Dr. Thad Howard. Allium texanum was split off from the larger A. canadense group and has proven to be very unique. The narrow blue-grey foliage forms an 18" wide mound, topped from mid-May to late June (NC) with a mass of 15" tall stalks, each topped with attractive umbels of white flowers. By late summer, the deer-resistant clumps are dormant, but re-emerge in November. We're always nervous about the potential weediness of alliums, but this has been a "good actor" in our trials. We would like to thank Dr. Howard for sharing with us so we may share with you.
