Ornamental Grass: Adding Style and Elegance
There are many varieties of ornamental grass you can use in your landscape. Whether tall or short, warm or cool season, they add texture and style to your landscape.
Choosing a variety to add to your garden depends on a few things.
- Where you want to put it (sun vs shade)
- Do you want tall or short ornamental grass?
- Do you want something colourful or something with vertical strips?
- What about spreading by clump forming or underground runners
- Which ones look best in containers
These are all things to think about before you purchase these showy plants.
Warm season vs Cool season grasses
What's the difference?
- They love the hot, dry summer and start growing when the night time temps. stay above freezing in late spring.
- warm season grasses don't like to be disturbed when their roots are cold so dividing them in late spring is perfect.
- They won't get their plumes until well into summer up until the first frost.
- Cool season grasses love the cooler weather and start to grow as soon as the weather stays above freezing during the day.
- It's best to divide them in spring and fall as it's hard on them if divided when it's to hot.
- They start to get their plumes in early summer and hold them through winter..
Mixing both warm and cool season grasses is a good idea for having interest from mid spring until late fall.
Ornamental Grass: Adding Height to Your Garden
Growing 5' and above they are perfect for adding height to your gardens. They also make great privacy barriers or windbreakers.
Below are the grasses that I offer in my plant nursery.
Karl Foerster (Calamagrostis x acutiflora)
This feather reed grass has dramatic red-bronze plumes early to midsummer and will beautify your garden year after year.
This is one of the cool season grasses so dividing in the spring or fall is preferred.
It can handle full sun to part shade and will grow in any soil type, including sand and clay.
Flame Grass (Miscanthus sinensis var. purpurascens)
Growing to about 5-6' tall, it turns a brilliant reddish orange in fall after a long hot summer. It likes to stay moist during the summer but not water logged and loves full sun.
It's a warm season grass so dividing should be done when new growth starts to appear in mid to late fall.
Sweet Flag (acorus gramineus)
An easy to grow perennial that likes wet areas. Growing Sweet Flag adds a brighter yellow-green to your gardens. When the leaves are crushed it gives off a sweet scent.
It's a warm season grass.
Ornamental Grass for Ground Cover
These ornamental grasses stay on the shorter side of under 5'. They are perfect for ground cover or adding colour to your landscape and they are low-maintenance.

Hameln Fountain Grass (Pennisetum alopecuroides 'Hameln')
A dwarf among fountain grasses, it only gets 20-30" tall so it's great for using in smaller gardens.
It loves full sun to light shade and because it's a warm season grass, it like to be divided in late spring once the soil warms up and it begins to grow.
Bowles' Golden Sedge (Carex elata ‘Aurea’)
With bright yellow blades that carry through out the season, it will brighten your shade gardens but also does excellent in full sun. It does very well in wet to moist soil.
