The photo on the website doesn't really capture the true colour of the leaves, it's misleading.

Description

The 'Obsidian' heuchera has dark foliage almost black, brown tinged with violet, with a shiny appearance which gives it the name of this hard stone. The evergreen foliage is decorative for 9 months out of 12.

With a moderate habit, about 40cm (16in), this heuchera pairs well with lighter brunneras, heucheras or hostas.

For neutral to limestone soil, they are excellent evergreen field of plants for sun or partial shade.

Planting and care

Prepare a planting hole measuring 20 cm (8in) x 20 cm (8in) x 20 cm (8in). If your soil is heavy, mix some compost with the crumbled soil, partially refill the hole, and place your seedling (after removing the pot) so that the top of the plant's root ball is covered by 3 cm (1in) of soil. Adding a base fertiliser (dehydrated blood, horn powder) will nourish your plant during its rooting period without the risk of burning. Firm the soil and water generously to eliminate air pockets. If the weather is dry, you will need to water regularly for a few weeks to facilitate your plant's establishment. Heucheras renew their foliage in late winter, and we recommend cutting back the previous year's leaves in January or February.
