Phlox ovata

5 Photos


Phlox ovata (mountain phlox) and was formerly called Phlox latifolia. This species forms a low mass of basal foliage from which flowering stems arise in mid-spring. Phlox ovata was planted later than most of the other phlox in our trial and therefore did not reach a truly mature size until the final year of the trial. This slow start is the main reason why Phlox ovata did not score higher. However, this species has a lot of potential thanks to its excellent powdery mildew resistance.
