This annual Texas native is not very common, though we did see the ones shown above at Tandy Hills. The subtle blue-purple flower deserves more respect than it gets, being out shown by other grand Texas natives like the bluebonnet. You may know this genus as also Lisianthus, which can be found at garden centers. Wildflower.org suggests their rarity is due to their beautiful stature and having been picked too much that they cannot reseed. In the gardening world there are many varieties and cultivars, so you’ll be able to find some variety.
