The new hybrid X Heucherella plant named ‘Catching Fire’ with rugose, downwardly-cupped, palmately-lobed foliage changing from vibrant yellow with cherry-red flame surrounding the veins in the spring to lime-green with mahogany pattern around veins. ‘Catching Fire’ is vigorous and produces many airy panicles with numerous sterile creamy-white flowers beginning late spring and exhibits good heat and humidity tolerance. The plant is useful for landscaping as a specimen color, en masse, or as a container plant.
