Great Garden Plants Coral Bells

While this variety is bred to handle heat and humidity better than many other Heuchera, it still prefers shade or part-sun conditions. In cooler climates, it may tolerate more sun, but in hot regions, it should be protected from intense afternoon rays to prevent leaf scorch.

You can expect 'Red Lightning' to reach a mature height of 11 to 16 inches and a spread of about 18 inches. Because of its compact, tidy habit, it is well-suited for containers or smaller garden beds where space is limited.

It is considered a low-maintenance perennial. The foliage maintains its color from spring through fall, and the plant naturally keeps a tidy shape, so you generally won't need to do much pruning beyond removing spent flower stalks.

'Red Lightning' is hardy in zones 4 through 9. This wide range makes it a versatile choice for many different climates across the country.

One of the key features of this variety is its color stability. The vibrant chartreuse leaves with dark red veins are designed to maintain their bright, high-contrast appearance consistently from spring all the way through fall.
