Favourite Ornamental Grasses: Part 1


I am a sucker for a clearance sale. 

Back in early July, I worked my way into a throng of bargain hunters encircling a big cart of closeout plants at my local Loblaw garden centre. The big attraction? The $1.99 price tag!

The selection of perennials on the clearance cart was telling. Almost everything was an ornamental grass of some kind. Why had spring shoppers passed on these plants?

I think the answer is simple: an ornamental grass in a small nursery pot is profoundly unsexy. Shoppers are more attracted to plants with blooms (even I fall pray to this). There is just one problem with a purchase based on this criteria. If you buy only nursery plants in bloom, your garden will be full of June flowers with little to provide interest come late summer and fall. 

Choosing plants based on bloom overlooks the hidden potential that ornamental grasses have in spades! In the golden light of mid to late August, the magic begins and continues well into winter.

Even into winter ornamental grasses have a haunting beauty.

The other reason I think that grasses get left behind at the nursery, is that gardeners still have difficulty knowing how to use them. Ornamental grasses have really surged in popularity in recent years, but some of us still struggle to incorporate them in with other perennials (myself included).

I was looking through my library of pictures for this post, when I happened upon this garden. Seeing it again with fresh eyes (originally photographed it in 2014) I was reminded how cleverly this gardener used ornamental grasses. They are dotted in amongst the flowers all through the garden. Short grasses are down front, while taller grasses work like small shrubs.

In June, the clumps of ornamental grasses are somewhat understated, but by late summer I bet they steal the show!

Punctuating a mixed flowerbed with grasses is just one way to go. Massing grasses together is yet another approach.

One final set of inspirations as to uses of ornamental grasses. Think of them as shrubs and mix them in with perennials, other shrubs and conifers. The result is very textural.

The Holdouts


Today I am looking back on the golden days of autumn with an eye to fabulous foliage and perennials that continued to bloom well into the season.

 Fantastic Autumn Foliage:



Caryopteris divaricata 'Snow Fairy' is a plant that I always looks spring-fresh in late summer and fall. Full sun to light shade. Height: 60 cm and Spread: 60cm (very similar in size and shape to a small Spirea).

I have a number of Ninebark all of which look terrific in autumn.



Delicate looking Switch Grass, Panicum Virgatum 'Northwind' is one of my favourite grasses. It forms a neat, upright clump of blue-green foliage and tolerates a range of soils and moisture levels. This grass's best feature is the cloud of beige panicles that in appear in late summer. Full sun. Height: 120-150 cm (47-59 inches), Spread:60-90 cm (23-35 inches). USDA Zones: 4-9.


Evening Primrose, Oenothera tetragona is a bit of a nuisance because it spreads a bit to aggressively, but it redeems itself a little each fall when it turns a brilliant red. Height: 30-50 cm, Spread: 30-40 cm. Sun or part shade. USDA Zones: 3-9.


Euphorbia 'First Blush' likes dry, sunny conditions. It has light green foliage with cream margins and a blush of rose. In spring, it has yellow flowers, but the true beauty of this plant is in the foliage. Warning: this plant has a milky sap that is irritating to skin. It's a good idea to wear gloves when you are doing any pruning. Height: 25-30 cm ( 10-12 inches), Spread: 30-45 cm (12-18 inches). USDA Zones: 5-9.

Euphorbia polychroma 'Bonfire' has foliage that emerges as green and then quickly becomes a mix of maroon and green. It also has bright yellow bracts in June. In fall, the color seems to intensify and the plant becomes magical when covered with frost crystals. Full sun and normal or sandy, dry soil. Warning: this plant also has a milky sap that is irritating to skin. Again, it's a good idea to wear gloves when you are doing any pruning. Height: 25-30 cm ( 10-12 inches), Spread: 30-45 cm (12-18 inches). USDA Zones: 5-9.


Frost always does them in, but up until that point, Coleus looks terrific in conjunction 
with other autumn foliage.

Fabulous Autumn Flowers:


My picture does not do this plant justice. It is a great perennial to have for fall color.

Turtlehead, Chelone lyonii 'Hot Lips' has pink hooded flowers from August into September. Turtlehead prefers moist soil, but does fine enough in my garden. Full sun or light shade. Height:60-90 cm (18-23 inches), Spread: 45-60 cm. USDA Zones: 3-9.



Agastache 'Blue Fortune: I have featured this perennial any number of times, so I'll keep it short and sweet here. I love the frosty blue flowers and the pinkish cast the leaves take on as the temperatures drop. 'Blue Fortune' always looks great well into October.

Dwarf Calamint, Calamintha nepeta ssp. nepeta

 It's a bit of a shaggy dog, but the warm blue flowers are a nice color infusion to my fall garden.

Anise Hyssop, Agastache 'Little Adder' is a new introduction that is much shorter than Agastache 'Black Adder'. It blooms from late spring into fall. 'Little Adder' is only hardy to zone 5, so fingers crossed it makes it through an Ontario winter. Full sun and average growing conditions. Height: 40-45 cm (15-18 inches), Spread: 50-60 cm ( 20-24 inches). USDA Zones: 5-9.

Wild Bergamont or Monarda fistulosa

Wild Bergamont,  Monarda fistulosa is a skyscraper that can reach up to 5 feet. It started blooming in August and continued to flower into late September. Unlike modern hybrids, it can be prone to outbreaks of powdery mildew. Even so, it is well worth having in your garden. Bees and butterflies love it. Full sun to light shade. Average soil. USDA Zones: 3-9.



Two very similar Phlox. Both bloom a bit later than most of the other common varieties of Phlox.

Phlox paniculata Nora Leigh has white flowers with a magenta-colored eyes. The leaves are green with a narrow cream-colored margins. Full sun or light shade. Height: 70-75 cm (27-29 inches), Spread: 60-75 cm (23-29 inches). USDA Zones: 4-9.

Phlox paniculata 'Creme de Menthe' has wonderful green leaves with large, cream-colored margins. The flowers are also white with a magenta-colored eye. Full sun or light shade. Height: 90-120 cm (36-48 inches), Spread: 60-90 cm (24-36 inches). USDA Zones: 4-9.


I'll announce the winner of the latest book draw shortly.
Have a wonderful weekend!
