Direct Gardening Association’s Green Thumb Award Winner

Lovely garnet, many-branched stems hold upright clouds of daisy flowers in hues of gold and mahogany. A "tip of the garden cap" to David Cavagnaro, who shared the seed of this Iowa prairie flower with us in 2003, today, it is widely available, even across the pond in England! A biennial to short-lived perennial that blooms summer and early fall. Self sows.

Placement & Cultivation

This North American native is great for attracting bees & butterflies, and deer avoid it, making it a good choice for borders and meadow plantings. Excellent for bird-friendly gardens, it draws goldfinches to the seeds in fall. Blooms develop mid-summer and continue over a long period. Deadhead or cut for bouquets. It may require staking in especially windy locations. Divide every three years or so. Self-sows.
Final Spacing: 2'
Water Use: Medium Water Use
Watering Details: 1" a week. Tolerates some drought once established.
Soil pH: Prefers neutral but will tolerate slightly acidic to slightly alkaline
Fertilizer: Mix in about 2" of compost before planting, and top dress with an additional inch each spring.
Diseases & Pests: Avoid fungal troubles with proper spacing in a location with good air circulation. Snails and slugs might be troublesome with the seedlings. Sprinkle some crushed eggshells or iron phosphate pellets on the soil surrounding the plants.
When to Cut For Bouquets: Open flowers
