Drought tolerant: Water frequency must be increased in high temperatures.
Sun: Full sun to part shade. It does best against south or west-facing walls. More sun means more blossoms.
Soil: Well draining, pH 5.6-8.5 (acidic to alkaline).
Water once established: Once or twice a month in part shade. Weekly in full sun during the hottest parts of the year.
Mulch: Cover the root zone with organic mulch before the first predicted frost.
Prune: After the last frost, remove winter damage. Periodic pruning helps to keep it within bounds and improves stem and leaf density.
