Fun Facts
- 🌱 Weigela is native to Asia (primarily China, Japan, and Korea) and was introduced to European gardens in the 19th century, becoming hugely popular in Victorian landscapes.
- 🌱 The 'Bristol Ruby' cultivar was developed to improve upon earlier Weigela varieties, offering deeper red color, more compact growth, and superior reblooming habit.
- 🌱 Weigela blooms on old wood from the previous year, so winter pruning should be minimal to preserve next spring's flower buds—the best pruning time is immediately after spring bloom.
