The long (up to 2.5 inches) tubular red flowers of epilobium canum
, a shrub like plant with woody lower stems, are large and pretty, consisting of eight tepals, all curved outwards at the tips, and eight tightly-clustered stamens which project forwards by about the length of the tube. The plant branches readily and each stem bears many small green leaves, so the overall appearance is of a dense bush, which may have hundreds of flowers during optimum growing conditions. The blooming season is relatively late, from midsummer into fall. The long narrow flowers attract hummingbirds.
