Heucherella 'Sonic Smash'

Plant Type: Perennials

The dynamic foliage of this Heucherella has emerald green leaves with prominent deep red to wine colored veins, a light silver overlay and a scalloped green margin.  They measure 5-6 in. across and form an attractive, robust clump.  An excellent low maintenance perennial for the landscape that looks great all season.  This is a heat and humidity tolerant plant that is grown for its lovely foliage, though small white flowers are produced in midsummer.  This plant is a H. villosa hybrid.  The villosa species is a large, late blooming type that exhibits an increased tolerance of high heat and humidity over other species.  Most produce cream flowers in midsummer, though they are grown more for their fantastic foliage.  H. villosa is native to the southeastern United States. Heucherella is a hybrid genus produced from a cross between Heuchera and Tiarella.

Growing & Maintenance Tips:

Heucherellas grow most vigorously and have the stongest colors when grown in partial shade (preferably afternoon shade). They can also be grown in full shade but their growth rate will be very slow. Some varieties can withstand full sun in northern climates if they have consistant moisture, but their colors tend to fade with the intensity of the sun. The soil should be amended with organic matter prior to planting. It should also have good drainage and a neutral pH. Heucherellas are evergreen in areas with mild winters. If properly sited out of the way of winter winds and with reliable snow cover, gardeners in northern regions may also find their heucherellas acting as evergreens. If the plant looks tattered by early spring, shear off any damaged leaves to make room for the vibrant new foliage which will fill in quickly.
