Mock Orange is an ornamental shrub known for its fragrant, white flowers. The scent is often described as orange-like with a hint of jasmine. Attractive to pollinators, hummingbirds, and humans alike.

Mock Orange is highly versatile, and can be used as an ornamental shrub, either alone or as a hedge. It is well suited for streambank stabilization and riparian zone restoration, due to its ability to grow in low, moist areas as well as those that are high and dry. Lewis Mock Orange also has the capability of being used in soil bioengineering projects such as live staking.

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.
