About this plant
This plant is a native of the western part of North America, relishing cool conditions. It has given rise to some of the early and interesting hybrids and the source for the ruffled foliage of some of the modern forms. It makes a mound of foliage with long leaves having scallop shaped lobes that are generally evergreen. It will flower during June and July when it sends up long, slender, flowering stalks carrying rather trivial yellowish white flowers having red anthers. The plant itself stands around 30 cm in height, with 90 cm flowering spikes. It will make a clump some 45 cm in width when established.

Spring
Spring - late · Outdoors
Apply slow release fertiliser
Apply a slow release fertiliser which is spread around the root area of plants soon after they have come 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.
Spring · Planting
Replant every other year
Every other year the woody stem (in fact part of the rhizome) of heuchera can be replanted. When it reaches more than 7cm in length, simply dig the plant out and immediately replant it more deeply.
Summer
Summer-Autumn · Planting
Trim dead heuchera flowers
