Tiarella & Heucherella

A group of attractive foliage perennials for temperate to cool regions that prefer moderate to heavy shade ( they do NOT like afternoon sun ) on consistently moist, acidic to neutral, fertile, well drained soil that is rich in organic matter. They especially love a mulch of composed Oak leaves. These hardwood forest plants enjoy woodland conditions and can even compete with dense tree roots though with less vigor. Also they are NOT usually eaten by deer or rabbits! but do attract hummingbirds during spring. They do not tolerate of flooding or waterlogging. Winter mulch to prevent frost heaving is recommended in areas with severe winters and little snow cover.
Insect pest and disease problems are rare, though rush may occasionally occur. If rust occurs - cut off the affected foliage to encourage new growth.
Propagation is from seed or for cultivars, from division during late winter into early spring - do not divide while in active growth.

HEUCHERELLA
The hybrids between Heuchera & Tiarellas.
Hardy zones 3 to 7 in partial to full shade, preferring partial shade ( or morning sun ) on fertile, moist, well drained soil. They can only be propagated from division.
