Blue Sage

Salvia farinacea (SAL-vee-ah fair-ih-NAY-see-ah)

Family: Lamiaceae Unknown Herbaceous (3-15 ft)

Mealycup sage is a tender herbaceous perennial in the mint family (Lamiaceae) that has a long blooming season and attractive spikes of small violet-blue flowers. It is native to the south-central United States and northeast Mexico. It is typically found in prairies, plains, meadows, pastures, and woodland edges. The epithet is Latin for "flour” or “meal." This refers to the powdery white hairs on the calyx of the flower and upper stems. Grow this sage in full sun. It prefers well-drained, moist soil but tolerates dry clay soil. Although mealycup sage is reliably perennial only in the outer coastal plain, it grows beautifully during the spring, summer, and fall and functions as an annual in the mountains and piedmont. Propagate it by stem cuttings or seed. Pruning after a long blooming period will help encourage the plant to produce thicker, compact foliage and prevent it from becoming leggy. Mealycup sage blooms intermittently from spring until frost. Their coarsely serrated, green leaves are aromatic. The plant grows in thick, rounded clumps, usually no more than 1 to 2 feet tall and 1 to 2 feet wide. The nectar of the flowers attracts bees, butterflies, and hummingbirds. It is hardy from zones 8 to 10, and it is frequently grown as an annual in areas where it will not survive in winter. Mealcup sage is an excellent choice for prolonged color and low maintenance in the home landscape, particularly in areas of extreme heat. Different cultivars offer flower colors from blue to purple and even white and bicolors. It is an excellent bedding plant that looks neat and attractive all summer. Because the flower spikes are strong and upright, they make a good cut flower. Plant this sage in annual beds, along borders, and in naturalized areas. It is an ideal plant for butterfly, cottage, drought-tolerant, or pollinator gardens. This plant is seldom damaged by deer. Quick ID Hints: 2 to 3 feet tall, herbaceous perennial with erect, squared stems Opposite ovate-lanceolate green leaves with coarsely serrated margins Calyces short, cup-like, with inconspicuous teeth Corollas zygomorphic, large lower lip, blue-purple, white or bicolor Insects, Diseases, and Other Plant Problems: Mealycup sage generally has no serious insect or disease problems. It is susceptible to downy mildew, powdery mildew, and damping-off. Well-drained soil and good air circulation are required. Some cultivars have shown a fair amount of resistance to phytophthora (where fair is defined as less than half the plants studied dying of the disease.
