Sulphur-Flower Buckwheat

The Eastern Redbud is known for the pea-like pink buds that emerge in clusters on the bark, embellishing the tree in stunning flowers. They have a longer bloom time, sometimes for two to three weeks before the heart-shaped leaves emerge for the summer. Inedible pods emerge that turn brown in the summer, this tree is a part of the bean family.

Native to the Eastern North America. The Eastern Redbud can tolerate acidic and alkaline soil. Plant this as a beautiful understory species or shaded residential yard or garden. The bright pop of color will make an attractive ornamental tree.

Sulphur-Flower Buckwheat is a native perennial wildflower known for its dense clusters of cream to yellow flowers. The long-lasting blooms persist from late spring into summer, providing an extended nectar source for a variety of pollinators. The flower buds are often red-tinted before opening. As the blooms age, they shift to orange or red, adding seasonal interest and making them well-suited to dried flower arrangements. Its seeds are also eaten by birds, adding to its ecological value.

Depending on climate and conditions, Sulphur-Flower Buckwheat may be evergreen to semi-evergreen, or its foliage may turn red during fall. Its deep roots and spreading growth stabilize rocky or sandy soils, making it useful for erosion control. Exceptionally hardy once established, it requires little care and thrives in challenging environments, making it an excellent choice for pollinator gardens, naturalization, and ecological restoration projects.
