Abstract
The new and distinct cultivar of Echinacea plant named ‘Knock 'em Red’ with fragrant inflorescences on strong well-branched stems above dark green foliage. The inflorescences produce single whorls of long, broad, overlapping, mostly-horizontal, lightly sweet, bright crimson ray florets that change with maturity to more reddish and then mauve before dehiscing. The new plant is vigorous and produces a compact habit and flowers from mid-summer to fall frost. The new plant is attractive and suitable as a potted plant, for the landscape, and for cut flower arrangements.
