Annuals, Perennials, Flowers
Most primroses are native to the Himalayas and cool regions of southeast Asia and Europe. The plants form a foliage rosette; at bloom time, typically circular, sometimes fragrant flowers with five petals rise above the leaves. The petals usually overlap and are often indented at the apex, sometimes so deeply that each flower appears to have ten parts. Blossoms may be borne on individual stems, in clusters at stem ends, or in tiered, candelabra-like clusters along the stem.
Most primroses are spring blooming, but some start flowering in mid- to late winter in mild climates, and a few bloom in early summer. Some go dormant in late fall or winter; mark their location before they disappear.
Nearly all are good plants for the woodland garden.
Grows to 1 ft. high and wide. Perennial, but best treated as an annual. Soft, hairy, roundish leaves have hairy leafstalks; these hairs (except on Freedom and Libre strains) may irritate skin. Produces large, broad clusters of 1 1/2–2-in.-wide blooms in white, pink, salmon, lavender, or reddish purple in winter and spring; nearly ever-blooming in cool-summer areas. Use for bedding where winters are mild, as a houseplant in colder regions.
Flower stalk to 2 ft.; flowers are 1 in. long and golden yellow with a purple-black midrib and veins.
