Chim Chiminee Mix Rudbeckia

Chim Chiminee Mix Rudbeckia item #07655

Great annuals for adding color to beds, pots, and mixed containers. Attractive, daisy-like flowers attract butterflies and are good cut flowers. Sow in the garden after all danger of frost has passed in spring. Can start seed indoors 8 to 10 weeks before outdoor planting time. Do not cover seed, as light promotes germination. Water gently to prevent disturbing seed.


A heat and drought-tolerant annual that prefers well-drained soil. Deadheading promotes continued blooming, so there is a good excuse to cut the flowers for arrangements. Can leave some uncut stems in fall for birds to feed on and remove them in late winter or early spring. Best grown as annuals, they can be short-lived perennials or biennials. Don't count on plants to overwinter in zone 5 or colder climates, but some may survive in mild winter areas (zone 7 or higher). Often reseeds in gardens.
