One of my favorite annuals, heirloom Drummond's phlox varieties come in a rainbow of colors, from pure white, through pastels of yellow and buff to saturated hues of salmon, rose, crimson and purple, many with contrasting eyes. An 1897 catalog even lists one as Black Brown, describing it as the darkest available, and unfortunately lost since. An old-fashioned cut flower that lasts well in the vase, it is lovely grown in drifts along the garden's edge and in containers. Annual phlox is covered in bloom all summer and fall in moderate heat and humidity. Deadhead for continual bloom and provide good soil drainage and ample air circulation to avoid any problems.
