In the garden

Before planting, dig in some well-rotted garden compost. They're happy on most soils, as long as you improve the drainage of heavy clay, or keep them watered in summer if you have dry soil. The great thing about this group of plants is that they'll thrive in either dappled shade all day, or over half a day of full shade. In particular, if you have a spot that is in full shade around noon and the early afternoon, these fellows will love it, because full midday sun in summer can burn their leaves a bit.

Heucheras have a tendency to gradually work themselves out of the soil, so give them a mulch of garden compost or leaf mould around the crown each spring to settle them back in.
Divide your plants every two or three years to keep them looking their best.

Did You Know?

Obsidian is volcanic glass, and was the sharpest material available for most of human history: no steel blade can be hand-polished anywhere near as razor-sharp as a perfect flake of obsidian. It is still sometimes used as a surgical scalpel for work that is too fine for a metal knife.

Planting Instructions

Dig in garden compost or leaf mould when planting, in semi-shade. Space 30-40cm apart and water in well. Keep watered until established. Cut down spent stems after flowering. Divide congested clumps in spring and mulch around the crown with organic matter.
