Light. Full sun gives the fastest growth and the most flowers.
Water. Water while it establishes, then little or not at all. It is highly drought tolerant, and too much irrigation is its main problem.
Soil and feeding. It does well in poor, sandy soil, acidic or alkaline, and also grows in loam or clay. Rich soil is not needed.
Size. Grows to about 1 ft tall and spreads 3–5 ft. Plant about 4 ft apart; it forms a solid cover in 18–24 months.
Good to know. A Florida endemic, listed as endangered in the state. It tolerates salt wind, blooms all year and feeds butterflies. Plant only local verbenas nearby, since related verbenas hybridize.
