The Grande Heuchera are bred for an impressive size with large, leathery leaves on an extra large clumping plant. If you're landscaping a shade garden and wanting plants that will fill the space these are an excellent choice.
Heuchera Grande Black has large wavy leaves in black to dark burgundy, and is almost twice the size of a regular Heuchera. It's a hardy performer in a range of climates from the North to the South of New Zealand.
As with all heuchera some shade is needed and take care not to bury the crown when planting.
