Fun Facts
- 🌱 Forest Pansy's deep purple foliage is brightest in full sun; in partial shade, the leaves remain more green. The color intensity can vary year to year based on weather conditions and sunlight exposure.
- 🌱 Unlike many redbuds, Forest Pansy is grafted onto Eastern redbud rootstock, making it genetically identical to the original specimen tree discovered in a forest in Indiana in the 1940s.
- 🌱 The tree's scientific name, Cercis, comes from the Greek word for 'weaving shuttle,' referring to the elongated shape of its seedpods, which were historically used as a weaving tool inspiration.
