About this plant
This is a quiet looking alumroot with rather rounded lobed dark green leaves that make a good foliage clump. It sends up long and slender flowering spikes, a soft brownish red and carrying creamy yellow flowers from brown calyces. It is a good carpeting plant and has a tough constitution. The plant is better known through its showier cultivars. Give it a sunny or partially shaded site in fertile soil that is well drained but always has moisture in it. This stands around 60cm (2ft) high with a 30cm (12in) spread.

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
