![]() The gracefully arching stems of this tropical native are covered in bright-green leaves and carry clusters of small sky-blue flowers from summer through late fall. The long, delicate branches can be trained to cover a trellis or pergola, or they can be pruned to form a loose and interesting shrub for a sunny border or containers. Profile
did you know?Also known as leadwort (it was thought to be a cure for lead poisoning), plumbago gets its botanical name from the Latin word for lead, According to Hawaiian lore, the essence of this flower restores love and harmony between warring family members. general maintenance:Prune throughout the season to maintain desired shape, or tie stems to trellis or fence as needed. In Zones 9 and warmer, prune hard in late winter or early spring to encourage branching. Where not hardy, move plants into a frost-free area before the first frost. pests/diseases:Plumbago is relatively carefree outdoors. Spider mites and whiteflies may occur when grown in a greenhouse or overwintered indoors. controls:Regularly hose off spider mites and whiteflies with a directed stream of water or apply insecticidal soap, following label directions. To discourage spider mites, mist frequently to increase humidity. how to sow/plant:In spring, choose a sunny, well-drained site and amend with compost or well-rotted manure. Set plants at the same depth they were in their original pots 2?4 feet apart. Water and mulch upon planting. water and fertilize:Keep plumbago moist during the growing season, and following label directions, apply a balanced, all-purpose fertilizer biweekly.
