Phlox bifida

by Iza Goroff

Phlox bifida is a native of the Midwest USA, in parts of Missouri, Iowa, southern Wisconsin, Illinois, Kentucky, Tennessee, and Indiana. It is a member of the Polemoniacae, the family which also includes the Jacob's Ladders.

Although it is sometimes called the Sand Phlox, Wherry thought the common name should be Ten Point Phlox, because of its deeply notched petals. Those petals give a snow flake appearance, though not with the hexagonal symmetry of a snow flake. The basic color of the flowers is a lavender which can look blue under some conditions. There are brilliant white flowered forms.

Phlox bifida has a similar landscape effect as the more common Phlox subulata. Its leaves are longer than those of P. subulata and not smooth, unlike P. subulata. P. bifida readily hybridizes with P. subulata; the vigorous H. Lincoln Foster hybrid 'Millstream Jupiter' is probably from that cross.

Phlox bifida is easy to grow in well drained, sandy soil. It prefers full sun, though will do well even in half sun. Though not an alpine, it is a rock plant in some sites in nature and has the habit of an alpine. It is very hardy, probably to at least -40 degrees F&C.
