Harvest Tips
Arizona Sunset is grown for ornamental flowers rather than harvest. Deadhead spent blooms regularly—pinch or cut just below the flower head—to promote continuous flowering throughout the season. Flowers last 1-2 weeks on the plant. For seed collection, allow some flowers to fade and dry on the plant in late summer; collect seed heads when brown and papery.
