About this plant
A rather elegant little plant with starry flat-faced flowers that have five petals, each with a broad 'V' cut into its apex. The flowers are coloured a pale blue-white with a pin-eye. They sit on slender needle-leaves coloured dark green, flowering in April and May. The species is found growing over a wide area across North America, in gorges, woods, streamsides and rocks. Grow in a rock garden, raised bed or in a gravel garden as it enjoys dry positions in light soil.

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.
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.
