This is not a plant for gardeners who believe a plant should grow well wherever the gardener wants to plant it. Try growing it in the heavy clay soils so prevalent in central Oklahoma and it roots so shallowly that its perennial potential is seriously compromised.
Plant it in light, or at least very well-drained, soil in full sun and it will respond with vigorous growth that easily self seeds. Individual blooms only last one day, but an established clump will bloom profusely for eight weeks in May and June. Cutting some stems back by half while the plant is blooming will extend the bloom season.
