Fun Facts
- 🌱 Tiarella is sometimes called 'Foamflower' because its delicate flower spikes resemble foamy spray, and the genus is known for producing airy, frothy-looking flowers.
- 🌱 The plant spreads via runners (stolons) that root along the stem, allowing a single plant to colonize large areas over time, making it exceptionally efficient for groundcover purposes.
- 🌱 The common name 'Cutting Carpet' refers to both its resemblance to a woven carpet on the forest floor and its origin as a selection bred specifically for dense, compact coverage.
