Harvest Tips
Scotch heather is grown as an ornamental shrub rather than harvested for crops. Cut flower stems for arrangements in late summer when flowers are fully open but fresh. For dried flowers, harvest when blooms are fully developed and hang bunches upside down in a warm, dry location. Foliage can be harvested year-round for crafts or medicinal tea.
