About this plant
A slim-line phlox with long slender lance-shaped leaves arching out from the upright stalks. At the stem tops are the clusters of simple rounded flowers which come in a range of pink and lavender tints, occasionally even white. It is summer flowering. Found growing in the USA in, among other places, the Appalachians, often at altitude, and growing in the margins of woods or even meadows. There are a number of subtly beautiful cultivars that are more commonly seen than the species.

AutumnNow
Autumn - late · Planting
Prune foliage back
Cut foliage back to the ground in late autumn.
Some plants often present good autumn colour which can be an asset in the garden. It is worth delaying the autumn trim until such foliage displays are over.
Autumn - late · Planting
Divide every 3 years
Physically divide clumps every three years, or the plant will flower and grow less well. Discard or give away unwanted portions, or replant them to make a larger display. Plants can sometimes take a while to recover from this procedure.
Spring
Spring - late · Outdoors
Feed with slow release fertiliser
Apply a general purpose slow release fertiliser, spreading it around the root area of the plant as it is coming into growth. (Or apply a liquid feed at regular intervals throughout the growing season.)
This is a simple way to provide a nutrient boost as a single annual procedure.
Spring-Autumn · Outdoors
Water to keep the soil moist
For best results, this plant needs soil that is always moist. Water deeply and regularly as soon as soil appears dry. Even for established plants in the ground, a dry week can cause problems with some soils. Check plants in pots more often, especially in hot weather. Or install an automatic irrigation system which will do the hard work for you, even when you are away on holiday.
Without regular watering some plants never fully regain their beauty.
