Salvia farinacea is a herbaceous perennial that is commonly grown as an annual in most cold winter areas. Several cultivars are available ranging in height from 12 in (30.5 cm) to about 4 ft (1.2 m). Mealycup sage, as this plant is commonly called, bears multiple spikes of blue flowers over a long season starting in spring. Leaves are long and toothed, soft and light green tending to silver, especially the undersides.
