Gardeners' Notes:

Positive coriaceous On Jun 2, 2014, coriaceous from ROSLINDALE, MA wrote:

Upright growing but short---not over 18". Looks like a dwarf garden phlox (P. paniculata) with narrower, shinier leaves. Tough, easy, and adaptable, requiring little care.

Does not get powdery mildew. More tolerant of heat and humidity than garden phlox (P. paniculata), and a better choice for the US southeast.

Blooms a month earlier than garden phlox (P. paniculata), at the beginning of June here (Boston, Z6a). Very long blooming.

Highly adaptable as to soil type and pH. Performs well in partial shade.

Space these 12-18" apart.

Most easily propagated by dividing the root ball in early spring. Stem cuttings can be rooted. Seeds can be sown, but may not come true to type.

According to Charles Oliver, this is actually a selection of P. triflora, and is identical to the plant known as Phlox carolina 'Bill Baker'.

The Royal Horticultural Society has granted this cultivar their coveted Award of Garden Merit, under the name of Phlox carolina 'Bill Baker'.
