Panicum amarum 'Dewey Blue' (20)ct Flat
Common Name: Grass-Ornamental, Bitter Switch Grass
Zone 4 to 9, Full sun
Plants reach 3 to 5 feet tall and 2 to 3 feet wide.
This showy blue grass, with fountain-like habit, offers a very long season of interest in the garden. The glaucous grey-green to grey-blue leaves have an upright arching habit, which makes it a choice focal point or specimen for the center of the border. The height and habit of this plant varies depending on the soil fertility and available moisture. It is more upright and shorter in less fertile, drier soils.
In late summer or early fall (depending on your climate), strong, upright to arching stems are topped by light, airy, blue-tinged flowers followed by tan seed panicles which continue to provide visual interest well into the winter months.
Named for a beach town, Dewey, Delaware, 'Dewey Blue' is a native grass that is naturally found in the sandy coastal soils from Delaware to Florida and west to northeastern Mexico. It is used extensively to help stabilize sand dunes and thus grows best in dry, sandy soils. This grass is very low maintenance and easy to grow, making it a great choice for busy homeowners or beginning gardeners.
This grass is native to coastlines where the soil is sandy, dry, and infertile and the climate is sunny. Therefore, it grows best in these conditions. However, it will also grow in average to loamy soils with dry to average moisture levels. It does not perform well in clay or wet soils.
Panicum is wind and salt tolerant, making it a good choice for seaside gardens or along roads that are salted in winter. No serious pests or diseases are known to affect this plant. Propagate it by division in spring after cutting the dried foliage back to ground level.
Attributes: Border plants, Cut flower or foliage, Drought tolerant, Mass planting, Rock gardens, Salt tolerant, Specimen or focal point plant, Deer resistant.
