Blue phlox (Phlox divaricata 'Clouds of Perfume')
floks div-air-ih-KAY-tah
Genus:  Phlox
This is a very fragrant native woodland phlox with powder-blue flowers in spring. Reaching only 1 foot tall, it can spread to almost 2 feet and makes an attractive groundcover under shrubs or planted with other spring-blooming wildflowers. Leaves are semi-evergreen and hairy; stems root along their length. The blue flowers are salverform with petal lobes. This plant attracts hummingbirds and butterflies.
Noteworthy Characteristics:  Very fragrant. Spreads by stem roots.
Care:  Grow in humus-rich, fertile, moist but well-drained soil in partial shade.
Propagation:  Sow seed in a cold frame when ripe or in spring. Take basal cuttings in spring or root cuttings in early fall or winter. Detach rooted stem pieces in spring or early autumn.
Problems:  Powdery mildew, stem canker, rust, Southern blight, stem nematodes, leaf spots, leaf miners, and caterpillars. Rabbits can also cause damage.
