Heucherella Stoplight

Stoplight Foamy Bells

Heucherella ‘Stoplight’ is a colorful foliage perennial valued for its bright chartreuse leaves accented with a bold red starburst pattern in the center. This hybrid between Heuchera and Tiarella forms a compact, mounded clump of deeply lobed foliage that maintains its vivid lime-green color throughout the growing season while the central red marking adds striking contrast. In late spring to early summer, slender stems carry airy sprays of small creamy-white flowers above the foliage, adding delicate vertical interest.
