Planting
Use full sun with gritty, alkaline soil that drains freely. Choose its position carefully and leave established roots undisturbed; cooler summer conditions suit it best.
Care
Cut back after flowering to keep growth dense and limit spreading. Without trimming, long bare stems can develop with foliage concentrated at their tips.
Before planting: Excess moisture encourages root rot and mildew, and hot summers can cause the plant to struggle.
