Cercis canadensis, more commonly known as eastern redbud, belongs to the Fabaceae, or legume family, and is native throughout woodland areas along the East Coast, from New Jersey to Florida and across to Texas. These trees are often small and multi-stemmed, so they are popular native trees for urban and suburban landscapes. Eastern redbuds are angiosperms, meaning they produce flowers and fruits. In the case of the eastern redbud, its fruits are legumes, similar to peas and beans. The tree’s flat pod fruits are around three inches long, ripen around October, and can survive through winter. They, along with the pink flowers the tree produces, are safe to eat.
The eastern redbud’s bark is unique for a few reasons. It is hardwood and very dense, with a reddish inner bark. Young trees are smoother and have a brownish-grey color, while older trees tend to have more of a scale-like texture. The bark can be used for medical purposes. It has high levels of tannin, a bactericide that fights infection, and it has been used to fight coughs, colds, fevers, and even influenza. Read More

Questions to Explore
- How effective is the tannin molecule within the bark, and how does it compare to other forms of tannins?
- Is there a big difference between the reproductive ways of the Eastern redbud? Are there any complications when it comes to pollination on the same flower compared to pollination on a different tree?
- Is it possible for the Eastern redbud to have too many rhizobium bacteria on its roots? If so, then how much would it take before it becomes harmful?
