Heuchera ‘Green Spice’: Year-Round Colour for the Landscape
If you’re looking for a perennial that delivers colour and texture long after most flowers have faded, Heuchera ‘Green Spice’ is an outstanding choice. Commonly known as Coral Bells, this cultivar is prized for its dramatic silver-green foliage highlighted by burgundy-purple veins and dark leaf margins.
Unlike many perennials that rely primarily on flowers for visual interest, Green Spice earns its place in the landscape through its foliage, providing season-long colour from spring through fall and even into winter in milder climates.
Origins of Heuchera ‘Green Spice’
Heuchera is a genus of approximately 55 species native to North America. These plants naturally occur in a variety of habitats including woodlands, rocky slopes, prairies, and mountain regions. Modern Heuchera cultivars, including ‘Green Spice’, were developed by hybridizing several North American species to improve foliage colour, vigour, and garden performance.
‘Green Spice’ is often listed as a selection of Heuchera americana, a woodland species known for its decorative foliage and shade tolerance.
