Description

Plants bloom late spring into mid summer, producing tall stems ending in single terminal racemes that are club-like spikes of pink-rose colored flowers. The racemes are about 2cm thick and 5-9cm long and end 1 meter tall,upright growing stems. Plants grow in moist soils and under dry conditions go dormant, losing there foliage until adequate moister exists again. This species is grown as an ornamental garden plant, especially the form 'Superba' which has larger, more showy flowers. Typically alpine plants growing from short, thick rhizomes that branch. The foliage is normally basal with a few smaller leaves produced near the lower end of the flowering stems. The leaves are oblong-ovate or triangular-ovate in shape and narrow at the base. The petioles are broadly winged.
