Fall Colour

There are a number of garden plants quite willing to fly under the radar and selflessly let colourful bedding plants and flowering shrubs occupy the hot summer limelight. Instead, this humble lot opt to stand in the shadows and, like all good ingénues, wait for just the right moment to steal the show. That moment is fall. And when those shorter, cooler days arrive, these plants move front and centre to cap off the growing season with a dazzling display of colour and form.
Here on the prairies, the plants that save their best performance for early autumn deliver it in several acts, the first of which pertains to leaf colour. Most of our native plants are preordained to produce gold-coloured foliage. And while I like sunny colours, I have to admit that my eyes crave a bit more variety. Fortunately, there is a panorama of ornamental plants with red- and orange-coloured leaves that beautifully punctuate the fall landscape.

Amur Maple
Two of the stellar performers in the fall foliage colour category are amur maple (Acer tataricum ssp. ginnala) and serviceberry (Amelanchier). Amur maples are beautiful feature trees for small yards. Their orange-red fall colour and red winged seeds blaze with intensity, making them hard to miss and impossible to resist. Serviceberry, the other must-have tree for fall colour, turns a brilliant bronze-red. In winter, its bright-red twigs and smooth, steel-grey bark continue to wake up the white winter. If you don’t have either of these in your yard, it’s not too late to plan for next year. The fall is a great time to transplant trees. Just be sure to dig the proper hole (one that’s equal to the depth of the plant’s rootball and to at least three times its width). And don’t forget to water them right up to when the ground freezes.
Also on the list of overlooked-but-not-forgotten features is twig and stem colour. The reason we tend to forget about twigs and stems is that these structures, both figuratively and literally, play little more than supporting roles during the growing season. However, once the leaves and flowers have fallen and snow becomes the dominant background, the twigs and branches of trees and shrubs stand out beautifully against the landscape. Dogwood (Cornus) varieties with red and yellow branches, for example, provide beautiful colour that’s outstanding, and many deciduous trees, such as paper birch (Betula papyrifera), have interesting bark that can’t truly be appreciated until the leaves drop in the fall.
Lastly, it’s important to remember that mass displays of beautiful blooms and the fall season are not mutually exclusive. Garden mums are at their peak in September and October and easily compete with the best summer-blooming annuals. In fact, garden mums produce such a full display of flowers that one often can’t see the foliage through the flowers. Other plants that love the cool fall air are pansies and asters. By strategically planting a mix of fall-flowering plants, the illusion of spring can quite easily be brought to life…at least for a short time.

Another somewhat offbeat “fall flowering” category of plants is the ornamental grasses. Technically speaking, most perennial grasses, such as feather reed grass (Calamagrostis), bloom in the summer, but because their seed heads are so long lasting, these grasses can still be categorized as fall bloomers. The flower heads of grasses will persist right through the winter, which adds a lot of interest to gardens during the non-gardening season.
In my opinion, any garden plants that bridge the four seasons are well worth planting. Having colour and interesting plants that come into their own during cool fall or cold winter days can really raise the spirits. I guess you could say that when it comes to stellar fall plants, its not how you start that’s important but rather how you finish.
