Gardeners' Notes:

Neutral Kell On Jul 11, 2006, Kell from Northern California, CA (Zone 9b) wrote:

Stoplight as a Heucherella likes more water than a Heuchera but let dry out some between waterings. The leaves are yellow to lime green with a a red splotch in the center, darker in spring. The leaves are much bigger and bolder than Sunspot though its flowers are not as showy.
