Several species of Phlox are native California wildflowers. Yet, the more popular garden phlox, Phlox paniculata, is native only east of Kansas. It can self sow where it gets water, and is naturalized in the Pacific Northwest. It prefers rather rich soil and sunny exposure but is not very discriminating. A bit of partial shade might promote taller stems for cutting.
Mature garden phlox can be as tall and wide as three feet. Some modern cultivars stay a bit more compact. Dense panicles of small flowers may be as wide as six inches. Bloom is most commonly white, but may be pink, red, lavender or pastel orange. It is a splendid cut flower, with an alluringly rich fragrance. Bloom might continue for a month of summer.
Garden phlox is deciduous, so all canes die to the ground for winter. Mature colonies are then easy to propagate by division. Similarly, feral specimens that appear where they are unwanted are easy to relocate. Garden phlox can perform nicely in proportionately large pots and planters. It is uncommonly available from nurseries, but grows easily from seed.
