Small, deepest-red flowers appear in masses on exceptionally compact plants that top off at less than two feet. The flowers of Helenium are non-allergenic. Instead, it gets its name from the old-time use of the dried, powdered root for snuff. Helenium is a wonderful perennial that is easy to grow and provides months of fabulous colour from midsummer through early fall. Their tall stems and long lasting flowers make them ideal for cutting.
