Harvest Tips
Harvest flowers when fully dried on plant for best color retention (typically late summer through fall). Cut entire flower stems 4-6 inches from the base using sharp scissors or pruners. Bundle loosely and hang upside-down in a warm, dry, dark location for 1-2 weeks to complete drying. Alternatively, leave flowers on living plant and harvest as needed. Foliage can be harvested any time for fragrance; best picked in morning after dew dries.
Fun Facts
- 🌱 Helichrysum flowers are called 'everlastings' because the papery bracts don't wilt; they naturally desiccate on the plant, retaining color and form for years in dried arrangements.
- 🌱 The 'Dargan Hill Monarch' cultivar was specifically selected for its rose-pink flower color and superior vigor compared to wild-type Helichrysum italicum.
- 🌱 The foliage smells faintly of curry (hence the common name 'curry plant'), though it has no culinary use as a curry spice and the scent is more fruity-herbal than savory.
