Colors of Phlox

White Phlox

• "Shorty White" grows to 15 inches tall, making it suitable as a container plant, notes Perennial Resource. Shorty White is a cultivar of garden phlox (Phlox paniculata) that produces white blooms during July, August and September. The plant attracts butterflies and hummingbirds, a trait of many of these species, and it grows reliably in U.S. Department of Agriculture plant hardiness zones 4 through 8.

  White is one of the possible colors of moss phlox (Phlox subulata), a cold hardy phlox species for zones 3 through 9. Growing to just 6 inches tall, moss phlox works well in rock gardens, as ground cover or around foundations, where it takes to the dry soil.

Pink Phlox

• The petals of Phlox paniculata "Eva Cullum" are lighter on the outer portions of the petals, but dark pink in the center. This cultivar reaches heights between 28 and 34 inches, grows in USDA zones 4 through 8 and needs full sun, like the majority of phlox cultivars do. Eva Cullum is a good choice for mass plantings. Native to the Southeast, smooth phlox (Phlox glaberrima) resists mildew better than most phlox types. Pink is a common color of this perennial, which grows between 2 and 4 feet and blooms from April into May -- much earlier than your typical phlox.

Blue Phlox

• The sand phlox (Phlox bifada) is a spring-blooming type appropriate for rock gardens and ground cover because of its short stature. Sand phlox has pale blue flowers, is native from Michigan through Oklahoma and thrives in shade or full sunshine. Sand phlox grows despite being in poor quality soils and it stands up to drought.

  "Blue Boy" is a much taller phlox, a cultivar of garden phlox generating blue-shaded blossoms during the summer months. It grows as high as 3 feet. Use it between USDA zones 4 and 8 in cottage and prairie gardens.

Red Phlox

• From July to September, cherry red flowers adorn the "Red Riding Hood" cultivar of the garden phlox. Use this form in USDA zones 4 through 8 in your bird gardens to appeal to hummingbirds. Red Riding Hood, at 2 feet tall, has stems stout enough so that you will not need to support them with stakes. "Starfire" is a garden phlox with deep red colors. The flowers grow densely along the stems. Like many phlox, good air circulation is key to preventing mildew on the foliage. Space them so they have plenty of room between them. The Missouri Botanical Garden advises to keep this phlox watered during periods of drought.
