Somewhat similar to gladiolus, but there are differences. Watsonia’s sword-shaped, 2 1/2 -ft.-long leaves are less rigid, and it has taller, slimmer flower spikes set with smaller, more trumpetlike, fragrant blossoms.

Watsonia pyramidata

Deciduous. Blooms in late spring, bearing 2 1/2 -in. flowers in pink, rosy red, or white on 4–6-ft. stems. Hybrid forms have pink, red, or lavender blooms. Foliage dies back after bloom, reappearing in fall. Does not need regular moisture during summer dormancy but accepts it if soil is well drained. In cold areas, treat like gladiolus: plant in spring for late spring and early summer bloom, then dig and store after the foliage dies down.
