Harvest Tips
White Heliotrope is grown for ornamental flowers rather than harvest. Cut flowers for fragrant bouquets when clusters are fully open, preferably in early morning or evening when fragrance is strongest. Cut just above a leaf node to encourage bushier growth. Flowers last 5-7 days in a vase; refresh water every 2-3 days.
