Rudbeckia maxima

Giant Coneflower

USDA Zone: 4-9

Plant number: 1.455.500

This species is a native wildflower from the Southern USA. Plants form a beautiful low clump of large powdery-blue leaves, then tall stems of drooping yellow brown-eyed daisies rise above in mid-summer. Great for cutting. Although nice at the border back, the foliage is outstanding enough to move right out front and centre. In mild winter regions the lower leaves may remain evergreen. Clumps may be easily divided in early spring. Stems are self-supporting and seldom need to be staked. Attractive to butterflies.
