Ornamental grasses can provide year-round interest while being easy to maintain and incredibly versatile. In the spring and summer, ornamental grasses are bright and lush and in the fall and winter, provide texture and color. They come in all sizes from small, mounding groundcovers to 12 feet tall flowering grasses. Their range in color, texture, height, and growing conditions, make them easy to place whether it’s in a contemporary design, cottage garden, or small container garden.
Designing with ornamental grasses can start to be overwhelming once you realize how many choices you have. But, if you can narrow down where you want grasses to go and how you want them to function in your garden, you can easily pick and choose from these lists to create a beautiful and lush landscape that you’ll love to look at all year long.
- Variegated Japanese Sedge (Carex morrowii ‘Aurea-Variegata’)– green and white thin, stiff leaves, mounding form, evergreen, works well near rain gardens, water gardens, or along edges of ponds

- Variegated Lilyturf (Liriope muscari ‘Variegata’)– evergreen grass-like perennial with purple flowers in spring and variegated light green foliage, spreads 12-24”
- Blue Zinger Sedge (Carex flacca ‘Blue Zinger’)– blue-green, finely textured foliage grows in clumps and spreads to be 12-18 inches
- Greater Wood Rush (Luzula sylvatica)– soft green arching foliage, also comes in variegated varieties, drought tolerant in shady areas, short spikes of greenish-tan flowers appear in Spring
- Golden Variegated Hakonechloa (Hakonechloa macra ‘Aureola’)– slow growing, deciduous, flowing golden yellow foliage, gets to be about 14” wide and tall, likes moist soil
- Seersucker Sedge (Carex plantaginea)– evergreen, bright green foliage has a puckering effect similar to seersucker fabric, flowers rise above foliage in Spring and are dark brown
- Bulbous Oat Grass (Arrhenatherum elatius bulbosum ‘Variegatum’)– green and white striped narrow leaves, works well in masses or as single accent plant
- Yellow Foxtail Grass (Alopecurus pratensis ‘Aureus’)– bright, yellow-green variegated foliage, also works as a groundcover, best color will appear once cooler weather sets in

- Prairie Dropseed (Sporobolus heterolepis)– tall, airy stalks of light green foliage are followed by fragrant tan panicles in summer, foliage turns coppery-gold in fall
- Mexican Feather Grass (Nassella tenuissim)– delicate, bright green foliage is topped by wispy tan flowers, sways nicely in the smallest of breezes, reseeds/naturalizes very easily so it should be planted in a woodland buffer, meadow or a similar area which allows for spreading
Coarse Textured Grasses:

- Bunny Blue Sedge (Carex laxiculmus ‘Hobb Bunny Blue’)– silvery-blue, dense mounding sedge with tiny yellow flowers in late Spring
