Foliage plants for lead and supporting roles in the garden

Raise your hand if you think foliage is just as important as the flowers in your garden. Foliage plants don’t necessarily have to be the star of the show—some plants are destined for supporting roles—but others definitely have superstar potential. And, of course, not all leaves are green. There is a whole rainbow out there waiting for their closeup in your garden.

Some plants are genetically blessed with great flowers AND leaves. I’m thinking of heucheras and tiarellas, while others have names that might fool you into thinking they have super-awesome flowers (i.e. Rex begonias), but they’re really all about the leaves.

When you’re thinking of spaces to fill in the garden, figure out which role your leafy plant can play and set the scene. Foliage plants can act as a backdrop, highlighting the attributes of other plants; they can provide a variety of interesting textures and shapes; they add multi-season colour; and leaf hues can complement and contrast with both annuals and perennials. If your garden is a blank slate, well then you can really plan out the structure and shape of the space, and figure out your plant composition. Think about grouping plants in threes or fives for impact.

In your pots, foliage can be thrillers, spillers, and fillers, depending on which varieties you choose. And don’t be afraid to use edible leaves in an ornamental container arrangement.

Perennial foliage plants

Tiny Wine Ninebark

One of my favourite additions to my front gardens in the last few years is my Tiny Wine Ninebark (Physocarpus opulifolius) from Proven Winners. Even though the leaves are a deep shade of maroon, this compact shrub is no wallflower. It really stands out. An added bonus are the lovely pale pink and white flowers that bloom in the spring (and sometimes I get a second round later in the season!). It’s very hardy (USDA zone 3-7) and likes full sun.

Japanese forest grass

On my walks into town, I pass through this lovely rock garden maintained by a local group of green thumbs, and this Japanese forest grass (Hakonechloa), cultivar unknown, is a cascading standout. I’ve seen some really stunning lime green varieties, too, that would look amazing against super dark foliage or vibrant flowers. They should be planted in partial to full shade, and are hardy in USDA zones 5-9 (I’ve seen a couple that are zone 4).


I’ve documented my love of heucheras (aka coral bells) on the site. For me its the diverse range of choices I have when it comes to colour. I’m talking super lime green to deep dark purple and almost black, reds, oranges, and browns. I started my collection a few years ago when I was trying to follow a “moody” colour palette for a fall container and I came across this lovely variety with cool green variegated leaves with purple undersides. When I took the pot apart, I planted it in the garden. Now I tend to pick one up each autumn, but I’ll choose it according to my colour scheme. An added bonus are the delicate blooms that shoot up like antennas. Heucheras like well-drained soil and partial shade, and they’re hardy in zones 4-9.

Here’s an example of a heuchera in a fall container arrangement.
