Our national attention is turning to climate change. All the data say it's crunch time, and that plants are essential for building communities that can withstand these changes. A 2016 report from the EPA explored ways green infrastructure can improve community resiliency. Experts and stakeholders outlined strategies to help communities prepare for and mitigate the effects of climate change. Strategies included managing flood risk, reducing urban heat island effects, and decreasing the energy needed to manage water. Ornamental grasses and sedges can be part of the answer in all the case studies cited in the EPA report. Grasses and sedges anchor the plantings that help clean our water, reduce flooding, and lessen the effects of rising temperatures. Let's work towards a better environment.

About this Variety

Chasmanthium latifolium. Known as River Oats or Northern Sea Oats, this US native produces a multitude of beautiful pale green seed heads in midsummer that are reminiscent of the sea oats found at the beach. Panicles drop under their weight and look absolutely beautiful when backlit by the sun. Chasmanthium latifolium is a tall ground cover that grows in just about any situation: sun, shade, moist or dry. This ornamental native grass is a great landscape solution for areas of dry shade. When planting, keep in mind that River Oats will spread and reseed, so place it in appropriate locations. When planted in sun, this plant may grow taller than four feet.
