Green Bulrush
Swamp White Oak

Green Bulrush is a common waterside plant, suitable for erosion control and land reclamation. Despite this, Green Bulrush is very drought resistant once established. Bulrushes can cool nearby areas on hot days.

Unlike many of the other waterside plants available, Green Bulrush does not attract wildlife. This makes it a good choice for surrounding residential water sources.

Green Bulrush is topped with spiky balls of florets, green in the spring and fading to brown in the fall.

The Swamp White Oak is a medium-sized deciduous tree native to North America. It is commonly found in swamps, lowlands, floodplains, and near streams and lakes. The leaves are two-toned, green on top and silvery-white on the undersides, adding to the visual appeal of this popular shade tree.

In the fall, the Swamp White Oak produces acorns which are an important food source for wildlife. It also provides a habitat for the larvae of many butterfly and moth species, playing an important ecological role. Although its growth is slow in the first few years, once the roots are established, it can achieve faster annual growth.
