Harvest Tips
Sunset Heather is an ornamental shrub, not harvested for food. Cut flower spikes in late summer to fall while in bloom for dried flower arrangements or fresh cut flowers.

Fun Facts
- 🌱 Sunset Heather gets its most vivid orange and red coloration during fall and winter when cool temperatures trigger pigment changes in the foliage—this is why it's prized in regions with cold winters.
- 🌱 Heathers have been cultivated for centuries, particularly in Scotland and Northern Europe where they naturally dominate moorlands; Calluna vulgaris is the primary heather species of the Scottish Highlands.
- 🌱 The name 'Calluna' comes from the Greek word 'kalluno' meaning 'to sweep clean'—historically, heather was bundled and used as a natural broom.
