The Heuchera micrantha 'Palace Purple' is a nice addition to your garden because of the beautiful colour of the leaves.

During summer the leaves turn more green. The foliage of the Heuchera micrantha 'Palace Purple' is essentially evergreen. That depends for a large part on the severity of the winter. In spring new leaves will replace the old ones.

This coral bells spreads through seed, but since the seedlings are easily removed this is not a problem. The older plants develop woody bases. I pull off the older parts of the plant and stick them in the ground. With some extra water they will grow further. You can also dig up the plant and put it back a little deeper into the ground. You can dig up the seedlings and replant them elsewhere if they grow in an unwanted spot. The best period for transplanting is early spring.
With some morning sun the leaves get a nicer colour. The Heuchera micrantha 'Palace Purple' is an easy to grow perennial that grows best in the shade.
