Product Details

Most of us grow native Northern Sea Oats (Chasmanthium latifolium) for the decorative flower heads that droop gracefully above wide, arching blades. Green in summer, they turn purplish bronze along with the yellowing fall foliage and will last right through the winter. This prolific self-sower can be managed by cutting bouquets of dried seed heads in the fall. Feature this Ornamental Grass as a single specimen or let it naturalize in lightly shaded areas.

Grasses, all from the family Poaceae, are as variable as people, and are widely used as foliage plants in successful gardens throughout the world. The value of these long-lived and low-maintenance perennials comes from the varied colors and textures of their foliage as well as their striking flower spikes. From earliest spring into the dead of winter, they offer an arresting display that complements flowering plants nearby while making an elegant statement on their own.

Landscape Plugs™ are a boon to gardeners seeking an easy, economical way to plant sizable swaths of native perennials. They are also an affordable way to purchase numerous plants that can be readily incorporated into existing large gardens or meadows. Landscape Plugs™ have deep roots (to 5”), which help plants establish quickly and provide erosion control. Most of these perennials will reach flowering size in their first year. They are a superb choice for creating habitat for wildlife. Many produce flowers that are favorite food sources for pollinators including bees and butterflies. Choose a mix of varieties (or call our Customer Service team for helpful suggestions) and create a garden that looks beautiful and bolsters biodiversity. Plugs are offered in easy-to-transport flats made of 100% recycled plastic that is recyclable (#6). Depending on the varieties you select, Landscape Plugs™ are offered in flats of 32 or 50 plants. Each flat contains a single variety. (Mixed flats are not available.)

The size of the plants we ship has been selected to reduce the shock of transplanting. For some, this means a large, bareroot crown. Others cannot travel bareroot or transplant best if grown in containers. We ship these perennials and annuals in 1 pint pots, except as noted. We must point out that many perennials will not bloom the first year after planting, but will the following year, amply rewarding your patience. We ship bulbs as dormant, bare bulbs, sometimes with some wood shavings or moss. Shrubs, Roses, vines, and other woody plants may be shipped bareroot or in pots. The size of the pot is noted in the quick facts for each item.


We ship our bulbs and plants at the right time for planting in your area, except as noted, with orders dispatched on a first-come, first-served basis by climate zone. We also ship a wide range of containers and planters, tools, supplies, fertilizers, garden wear, garden decor items, as well as indoor decorations like wreaths and dried bouquets when available. Estimated dates for shipping are indicated in the green Shipping Details box for each item. Please supply a street address for delivery. Kindly contact us with two weeks notice, if you'll be away at the expected time of delivery.


We guarantee to ship plants that are in prime condition for growing. If your order is damaged or fails to meet your expectations, we will cheerfully replace or refund it. Please contact our Customer Service Department at 1-800-503-9624 or email us at [email protected]. Please include your order number or customer number when contacting us.

Beautiful Beast

This sturdy, very graceful, grassy beauty is an invasive and persistent beast. Long, arching stems with beautiful bracts that flutter on the slightest breeze, the clumps are almost impossible to rip out, they anchor so successfully. Benefits: lovely dry stems in a winter arrangement and excellent erosion control. Advice: keep in a large pot.

Most varieties of ornamental grasses grow well in full sun and average garden soil. Keep their foliage for winter effect, cutting back all except the evergreen varieties (Festuca) before new growth emerges in the spring. Refresh Festucas by "raking" out the dried and dead leaves with gloved fingers.

Some species thrive in part shade, or even full shade, expanding the possibilities for Grasses in the garden. Hakonechloa is suitable in part shade, Sesleria in full sun to part shade, and Carex (Sedge) can thrive in full sun to full shade locations, depending on the variety. All need soil that stays evenly moist, although Sesleria can tolerate drier soils, and even drought.

Transplant and divide in spring. Grasses that spread by rhizomes ("run" ) can be invasive and should be divided every year or so. Grasses that grow in clumps die out in the center and need dividing every few years. 

Fertilize ornamental grasses in spring with a balanced fertilizer.  We don't recommend, however, fertilizing them their first spring to allow the roots enough time to settle in before having to support their very lush top growth. 

Ornamental Grasses appear to be quite deer-resistant. Evidently the sharp-edged leaves are unpalatable.

Grasses are at home in mixed borders of perennials, bulbs, and shrubs. Consider summer and fall-blooming perennials as companions: Achillea, Rudbeckia, Helenium, Asters, Monarda, Perovskia, Phlox, and Oriental Lilies. The large Miscanthus varieties work well in the back of a border, or even as single specimens. Because most grasses are sited in the middle or back of a border and are cut back in early spring, we like to plant spring-flowering bulbs around them for color early in the year. Daffodils, Tulips, and Alliums bloom while the Grasses provide little to look at. Then the Grasses and foreground perennials sprout and camouflage the bulbs' maturing foliage.
