Eastern Redbud
Water Arum

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.

Water Arum is a native perennial wetland plant known for its showy white oval sheaths (spathe) that surround a yellow-green, cylindrical flower spike (spadix). It has large, oblong, heart-shaped leaves on stems that rise above the water from shallow, spreading rhizomes. The blossoms are followed in late summer by tiny, pear-shaped fruits that ripen to bright red, adding ornamental interest to wet habitats.

Water Arum provides food for birds and small mammals that eat its berries, and its flowers attract pollinators. It can tolerate cold climates and forms colonies in shallow water and saturated soils. It is well-suited for ecological restoration, riparian planting, naturalisation, and habitat projects in wet and shaded environments.
