Harvest Tips
Sunningdale heather is grown for ornamental foliage and flowers rather than harvest. Cut flowers for arrangements when spikes are fully open but still vibrant pink. Trim lightly after flowering (late autumn or early spring) to maintain compact form, cutting just below spent flower heads but not into old wood. Avoid cutting into bare stems as regrowth is slow.
