Performance - 10 Excellent plant to use in the South. Is applicable in to zones 8 and 9 and is hardy in to zone 5. Easy to grow, prefers a light moist soil but adapts well to clays as long as the site isn't wet. I would avoid windy sites as it may be prone to dessication in summer and winter. Seems to tolerate confined root space and pollution under the harshest of conditions. One in town has been confined in a very small root space directly next to a very heavily traveled roadway and done quite well.
