Drummond’s phlox plants (Phlox drummondii) are named for Thomas Drummond. He sent seed to England from its native Texas, where trials began on their cultivation requirements. The plants don’t do well in the region due to its high rainfall and soil types, but they are still popular in the southwestern United States. When you know how to grow annual phlox, you will have a plant for life even if it dies out in the cooler season. This is because the seed heads are easy to harvest, store and plant indoors or out. The seeds germinate in just 10 to 30 days and provide spring blooms sometimes into early summer.
