Phlox glaberrima ‘Morris Berd’

Summary

Phlox glaberrima ‘Morris Berd’ is almost certainly a selection of Phlox glaberrima ssp. triflora, though very few people currently recognize it as such. This is an important distinction, because this subspecies is very different from other types of smooth phlox. Some horticulturists even advocate for making this subspecies its own species. Regardless, ‘Morris Berd’ is an excellent selection for the garden thanks to its disease-free foliage and profuse display of bright pink flowers in late spring. After blooming, the stems can be cut back and a new flush of leaves will develop to create an attractive and tidy appearance for the rest of the growing season. Although not fully evergreen, this basal foliage will persist through the winter months, which can help prevent soil erosion caused by harsh winter rains. Some horticulturists believe that Phlox glaberrima ‘Morris Berd’ and Phlox carolina ‘Bill Baker’ are actually the same plant, but our trial was not able to confirm this. However, their characteristics are similar enough that these certainly belong to the same species. The fact that these cultivars are currently attributed to two different species corroborates the confusion surrounding current phlox taxonomy.
