Everything’s popping up pink along city boulevards, in parks and front yards – the first of the spring-flowering shrubs are strutting their stuff. These pretty ladies are various species of the Prunus genus, a large genus that includes peaches, plums, cherries, apricots and almonds. In Calgary, the current explosion of pink blossoms comes from 3 different species.
Prunus tomentosa is first on the scene, with pale pink flowers that present before the leaves. Commonly known as Nanking Cherry, this medium to large shrub is native to China, Korea and the Himalayas. It has been cultivated in North America since early last century, providing a drought tolerant, cold hardy (Zone 2) shrub that grows to a height and spread of 2–3 metres. It produces small tart cherries that are excellent for jams and jellies.
Prunus triloba multiplex, the double-flowering plum, is by far the showiest of the three, its large double pastel-pink blossoms like cotton-balls along the many arching stems. A very vigorous grower, reaching 2–3 metres tall and wide, it will benefit from periodic pruning to remove any crossed or rubbing branches. This variety is sterile and doesn’t produce fruit.
Prunus tenella (Russian almond) is a smallish shrub with an upright vase shape and narrow green leaves that appear at the same time as the medium pink flowers. It’s compact and tidy, reaching only about 1 metre in height and spread. Very fragrant too, it is much underutilized in the urban landscape.
Many designers eschew the use of these shrubs because they’re “old fashioned”. It’s true they are, but they still have design value. They’re right at home in a Naturalistic garden and are especially useful in Asian-inspired or Colonial style gardens – and they’re reliably floriferous too.
When finished blooming, their design worth is more as a backdrop than a showpiece. Nanking cherry and flowering plum both have a lovely natural vase shape, as well as dark green, medium-coarse leaves which provide nice contrast to other brighter plants. Russian almond is much finer textured with lighter green leaves – together with its very upright branches, also provides good contrast in the landscape. And as woodies, they all offer much-desired structure to our gardens.
Perhaps it’s time to rethink these old-fashioned beauties – charm and grace come with age you know.Til next time, Sue

It’s interesting how plants come in and out of favor, but I don’t pay much attention to that notion. As you show so well, these would be valuable additions. The Prunus tenella (Russian almond) is interesting.
It does seem weird that particular plants would be considered fashionable or unfashionable – I mean either they have design value or they don’t right? But like you, I don’t have a lot of patience for ‘trends’ either.
Anyways, thanks for your comment and for being a faithful reader.
I find pink very subtle when it comes to gardening. A lot of my clients have a hint of pink, which makes their garden colourful. Beautiful post BTW.
Thanks for your comment Andrew, and thanks for reading!
