Plant Care

Prefers acid to neutral soil in a sheltered sunny spot.  If planting in limey soil add iron sequestrene to keep foliage grey.  New growth can be more easily damaged by cold weather so protection with fleece of small plants is advisable if weather conditions turn bad. Prefer not to be pruned, trim after flowering if needed.
