Heuchera Obsidian

Coral Bells

Perfect for a shady spot

One of the darkest of Heucheras with smooth, shiny leaves that are a bewitching shade of deepest purple-black. The handsome leaves set off spires of ivory white flowers through summer that are loved by bees.


Happiest at the front of a border in sun or part shade or in a container.


Good in any well drained soil. Place some coarse grit or sand in the planting hole if your soil is heavy and wet in winter. Use good quality loam based compost for container growing and raise the pot on 'pot feet' through the winter months to help with drainage. Remove untidy leaves in late spring and spent flower spikes in summer to encourage more blooms.

Planting instructions

Water the plant in its pot thoroughly before planting – give it a good soaking. Prepare the area by digging a hole twice the size of the pot. Dig compost into the base of the hole. Remove the pot and position the plant in the hole, with the top of the rootball about level with the surrounding soil. Refill the planting hole with a mixture of garden soil and compost, firming as you go. Water in well and keep well watered during the plant's first year.
