- 🌱 Common heather has been cultivated in Scotland for millennia and was historically used to thatch roofs, create brooms, and produce a natural dye. The 'Sunset' cultivar was developed relatively recently to highlight these ornamental qualities.
- 🌱 A single mature heather plant can live for 30+ years, making it an excellent long-term investment for gardens. Some wild heather plants in Scotland are estimated to be over 100 years old.
