General Culture:
Winter hardy to USDA Zones 8-10. In St. Louis, it may be grown as an annual in average, evenly moist, well-drained soils in full sun to part shade. Tolerates poor soils and some drought. Plants grown from seed sown directly in the ground after last frost date may not bloom. Seed should be started indoors 10-12 weeks before last frost date. Set out seedlings or purchased plants after last frost date. If desired, cut back and pot up several plants in fall or take cuttings in late summer for overwintering in a bright but cool sunny window.
Noteworthy Characteristics:
Native to Texas and Mexico, mealycup sage (see A605 herein) is a shrubby, clump-forming, tender perennial that typically grows 1.5-3’ tall on erect, branching, square stems. It features two-lipped, violet-blue flowers in axillary and terminal racemes (to 4-8” long) from summer to fall. Drooping, irregularly-serrate, ovate-lanceolate, gray-green leaves (to 3” long). ‘Victoria Blue’ is a compact, densely-branched cultivar that typically grows to 15-24” tall and features large deep blue flowers from summer to fall. Common name and specific epithet are in reference to the white powdery felting found on the upper stems and calyx (“mealy” means covered with powdery meal, “cup” is in reference to the calyx shape and “farinacea” comes from the Latin word for flour or meal).
Problems:
No serious insect or disease problems. Susceptible to downy and powdery mildew.
Uses:
Beds, borders, meadows, cottage gardens, cutting gardens.
