Several months ago I saw a beautiful purple flower in the grocery cut-flower case. Yes, lisianthus will grow here.
Hybrids often have larger foliage and flowers.
Lisianthus or Texas bluebell will grow in a sunny or semisunny spot in well-draining garden soil. Mature height is 2 to 3 feet. I saw bluebells along a Heights garden walkway this week. The flowers last a long time in a vase. Texas bluebell plants seem to be most readily available locally in mid- to late spring.
