Harvest Tips
Stella de Oro daylilies are ornamental perennials, not harvested for food. However, in some Asian cuisines, daylily buds are consumed as 'golden needles'—harvest unopened buds in early morning before they open, dry them, and store. For ornamental enjoyment, deadhead spent flowers daily to maximize blooming and plant appearance throughout the season.
