Great coneflower Interesting Notes

Commonly called cabbage leaf coneflower, Rudbeckia maxima is an eye-catching perennial native to warm, moist pine woods and plains from Arkansas to Louisiana and into Texas. However, its range of acceptable climates extends farther north. R. maxima is an herbaceous perennial in USDA hardiness zones 6 to 8; plants go dormant in late fall and the foliage disappears until spring. But being a native of warmer southern regions, this rudbeckia thrives in hot, humid summers, such as those in Brooklyn and elsewhere in the East and Midwest. Much more... Brooklyn Botanic Garden

 

Ornamental cultivars of plants which attract butterflies and birds in the wild, such as the cultivars of Joe-Pye-Weed (Eupatorium sp.), were selected for the new design. Black-eyed Susans (Rudbeckia fulgida) and Coneflowers (Echinacea purpurea) provide nectar for Monarchs, Swallowtails amd Fritillaries, and the Butterfly Bush (Buddleia davidii) is an excellent butterfly-attracting shrub. Lupines (Lupinus polyphyllus) and Columbine (Aquilegia sp.) are spring food sources for hummingbirds. Ornamental grasses and parsleys are excellent food plants for caterpillars. Tall Black-Eyed Susan (Rudbeckia maxima) seeds are highly attractive to goldfinches in the fall. Winterberry (Ilex verticillata) is a crucial shrub for providing a late-winter food source for birds.
