Elegant Northern Sea Oats Ornamental Grass (Chasmanthium latifolium) develops intricate "spangles" that wave and sway in the late summer breeze. They catch the dreamy tones of setting sunlight, too! You'll add effortless elegance with these showy natives! The late-season, flattened wheat-shaped seed heads are so eye-catching! Plus the pointed foliage brings visual interest.

Much like Bamboo, the short leaves of Northern Sea Oats Grass grow along the stems. Flat, upright and arching. The bright green leaves grow into a mounded clump for a welcome garden texture and motion.

Floral designers treasure Northern Sea Oats for the golden seed heads. Let them shimmer and dance in the summertime, then trim them to use in attractive dried flower arrangements all winter long.

Fall brings a warm coppery color and the seedheads can persist for fall and winter interest (and songbirds!). Leave the foliage standing to dry for winter interest as well, sculpting the snow beautifully. It's easy enough to tidy up in spring and you'll provide some much-needed shelter for the smallest citizens of your neighborhood.

A warm-season ornamental grass, Northern Sea Oats Grass is pest and disease free, but does take a bit longer to grow in the spring. However, once the warm weather sets in, gardeners in USDA growing zones 3-8 will enjoy a sun, heat, humidity, and drought tolerant ornamental until frost! Sea Oats are exceptionally cold hardy, so no need to protect them unless you're in Zones 3 or 4, or you are planting them in containers.

Planting and Application:

There is really only one way NOT to use this pretty grass. You don't want to place it in a tightly manicured garden bed in fertile soils without deadheading those spectacular seed heads off in fall.

New gardeners who love low-maintenance succulents should really take a look at growing Ornamental Grasses in containers on their balconies or first homes. Wise old gardeners know about their beauty...and appreciate how little care they require!

This free-flowing grass will self-sow volunteer seedlings the following spring if you don't deadhead in fall. Keep things easy for yourself by working with this trait, not against it! Fill those hard to mow slopes and hillsides that may be eroding with this pretty accent! Plant along the hell strip along the roadside or sidewalk, or along a pathway for some pretty, low-maintenance fringe.

A mass planting of "Spangle Grass" Sea Oats brings rhythm to your landscape design. Not only does the foliage flow in rippling waves as the wind blows through it, the seed heads catch and flash in the sunlight.

Why not place this in a wide, open area as a swaying en masse planting, and let it fill into a phenomenal groundcover? They look delightful all season long and require a single trim once a year. Place them 10 inches apart in a single species planting bed for a modern look in full sun. Or, use them as an arched underplanting under the dappled shade of a flowering specimen tree.

This is also a great choice for "Fillers" in container gardens. Pop several around a "Thriller" and keep it outdoors all year long. This charming container garden will thrive for many years.

This selection grows in full sun and is partial shade tolerant, which is a wonderful trait for wooded landscapes. If possible, situate it where the western sun will light up the copper fall foliage for a fiery display that sparks conversation.

Because Northern Sea Oats Grass puts up with periodically wet soils, it can be a boon for the edge of planned Rain Gardens. Cover the slope of the berm to help filter potentially polluted water runoff from streets and roofs.

You'll want it to self-sow when you use it like this. Every plant has a place, and this stunning Grass covers the ground like nothing else! Partner with other native grasses, perennials and shrubs for a naturalized planting or Cottage garden straight out of a fairy tale! They will look amazing with Purple Liatris and Coneflowers in a prairie or meadow garden too! Pollinators and songbirds will appreciate your conscientious choice!

Nature Hills loves native plants, and offers many in our extensive online catalog. Never fear, because we also protect local ecosystems with Plant Sentry™ to block shipments of any plant that does "too well" in your area.

#ProPlantTips for Care:

Northern Sea Oats Grass is easy to grow in full sun or in part shade gardens. Although the size of this lovely grass will depend on the growing conditions, they should still produce seed heads with at least four hours of sunlight a day.

Easy to plant and grow Grasses adapt to poor soils and periodically dry gardens, but will likely be shorter. They do best in rich, moist soils. Ensure they get a moderate amount of water on a consistent basis, especially for container-grown plants. Mulch around the plant to keep the root system cool and moist, but pull it back away from directly touching the crown.

Prune the dried foliage down to the ground in early spring. Do this simple task before new growth emerges. Warm-season grasses may take longer to green up in the spring, but really shine once the hot, dry summer weather kicks in!
