The Rhyne Garden at Delaware Botanic Gardens at Pepper Creek is a model for coastal stormwater management and flood control in residential and commercial development. Mass groupings of native perennials along the slope, together with different trees and shrubs, define the Rhyne conveyance with color and texture. This planting buffers, slows, and captures storm flow, promoting slope stabilization and treatment of runoff. Planted by DBG volunteers and staff, the garden includes more than 12,000 native perennial shrubs and trees. Selected for water tolerance and heat resistance, these plantings provide natural beauty as well as ecological services for pollinators. Its best management practices reduce the volume and flow of runoff, helping capture and absorb pollutants and sediments from parking areas. Root systems improve water quality through uptake and biofiltration of excess nutrients and chemical pollutants, while native plantings minimize maintenance and support a more diverse population of native pollinators and bird habitat.
