Creeping PhloxCreeping Phlox is also known as Moss Phlox. It is a very hardy plant that blooms early spring. Phlox should be planted in full sun, but in really hot regions, it may need some afternoon shade. If you are planting by seed, you will want to plant before the last frost in spring. Plant you seeds approximately 17-18 inches apart and about 1 inch deep. Keep the soil moist until they have had time to establish their roots. You may want to trim them back or “dead head” them after their first bloom to encourage new growth. This is an excellent plant to have “spilling” over the edge of raised flowerbeds.
