Harvest Tips

Fun Facts

🌱 Winter Heath Rosy Gem blooms reliably during the coldest months when temperatures drop below freezing, making it invaluable for providing color during winter dormancy when most gardens are bare.
🌱 This cultivar is part of the Erica carnea species, native to the Alps and other European mountain regions where it evolved to flower during winter thaws.
🌱 The name 'Rosy Gem' perfectly describes its appearance—a compact mound (rarely exceeding 12 inches tall) covered in jewel-like rosy-pink flowers that glisten in winter frost.
