Harvest Tips
For cut flowers, harvest in early morning when buds are just opening or flowers are fully open. Cut stems at a 45-degree angle above a leaf node. Flowers last 7-10 days in a vase. For seed harvesting, allow flowers to dry on the plant and collect brown seed heads in late fall; store in cool, dry location.
Fun Facts
- 🌱 Gold Ray is a compact cultivar bred specifically to be more uniform and shorter (2-3 feet) than wild black-eyed Susan varieties, making it ideal for smaller gardens and containers.
- 🌱 Black-eyed Susans (Rudbeckia) were named by early European colonists and are native to North America, with indigenous peoples using related species medicinally.
- 🌱 The distinctive dark purple-brown central disc is not actually the flower's center—it's composed of hundreds of tiny florets that collectively form what botanists call a disk flower.
