Heuchera

They really don't like to be scorched or dried out, so a cool situation, part shade suits them best. Ideally they can be replanted in fresh soil every few years. There are many new cultivars, which due to the vivid colours which some possess, may be difficult to place into  a garden setting! More established cultivars like 'Palace Purple', 'Obsidian' and 'Ruffles' may be easier to start with.
