Description from Great Garden Plants
Heuchera Obsidian is similar to the gemstone – it’s not only genuinely black, but has a glassy luster as well.
The leaves of this shade plant appear polished to achieve this gemstone effect. Dark 10 inches mounds of stunning foliage.
In late spring, creamy flowers rise up to 24″ tall. Very sun tolerant Heuchera that develops a highly reflective appearance the more sun it receives.
Heuchera Obsidian’s shiny black foliage is the perfect companion to Hardy Ferns, bold Hostas, & giant-blooming Hydrangeas.
Heucheras prefer a rich, humusy, moisture retentive soil If grown in more sun, give this gem more water. Once established, they can tolerate a great deal of heat, humidity and dryer conditions.
