Fun Facts

  • 🌱 Ruby Falls is a cultivar developed to address the common complaint about standard weigelas being too large; it's approximately half the size of typical weigela varieties while maintaining the prolific flowering of its parent species.
  • 🌱 Weigelas are native to East Asia and were named after Christian Ehrenfried Weigel, an 18th-century German botanist, making this ornamental shrub an international horticultural bridge.
  • 🌱 Ruby Falls can produce a second bloom flush in fall if deadheaded regularly and given adequate moisture, sometimes offering two distinct flowering seasons in a single year.
