Technically, Heucherella has no true species. This is because it is an intergeneric hybrid (a cross between two different genera - Heuchera and Tiarella).

Groups:

There are not formally named groups within Heucherella. However, you might see them loosely categorized by traits like:

Foliage Color: (e.g., "red-leaved Heucherellas," "silver-leaved Heucherellas")
Sun Tolerance: (e.g., "sun-tolerant Heucherellas," "shade-loving Heucherellas")
Flower Color: (e.g., "pink-flowering Heucherellas")

Cultivars:

This is where the real diversity lies! Cultivars are named varieties produced through breeding programs. Here are a few examples with some distinguishing features:

'Tapestry': Silver, green, and burgundy patterned foliage.
'Sweet Tea': Golden, orange, and reddish foliage.
'Pink Fizz': Pale green leaves with purple veins and pink flowers.
'Bridget Bloom': Pink flowers and reddish-purple leaf markings.
'Gold Zebra': Bright yellow leaves with dark red veins.
'Stoplight': Yellow leaves with dark red blotches.

Why No True Species?

Heucherella is a hybrid genus, meaning it originated from a cross between two different plant genera. Hybrids often have complex genetics and may not reproduce true to type from seed.
Cultivars are maintained through vegetative propagation (e.g., division, cuttings) to ensure they retain their specific characteristics.
