Hmm…sounds improbable perhaps? But then, what are those delicate white flakes drifting and fluttering on the lightest breeze?

The answer is petals….and the original owner of those petals is the Snowy Mespilus, or Amelanchier.

One of the finest and least demanding of small trees for the garden, whose virtues I’ve already hinted at previously, as March gives way to April and the countless thousands of poised Amelanchier flower buds open, I thought it high time to give these plants centre stage for a while.

Members of the Rose family – like so many other of the finest Spring-flowering woody plants – Amelanchier is a small and rather confused genus of trees and shrubs. There are anywhere between 6 and 35 species, depending on whose definition you believe. They are all, essentially, identical in their ornamental features, and what’s more the species have interbred with abandon to the point that definitive identification of many plants is all but impossible.

One species, A. lamarckii, is a good example. Considered to be a naturalised British plant, where colonies have spread thanks to the assistance of birds, this plant is, like all but two of the Amelanchiers, a native of North America, but “our” Amelanchier is not the same as the species that grows in the USA, and could be a different species, such as A. canadensis or A. laevis, or a hybrid of one or more of these species, or a hybrid with one of the indigenous Euro-Asian species. The truth is that the differences between all of the species are so small, and variable, that the best anyone can say is that an individual plant is closest to, say A. lamarckii…well, maybe.

But enough of that confusion, let’s focus instead on the many good points of these delightful trees. Their common names give a few hints of their attractions and also the considerable importance that the plants played in the lives of Native American and European settlers alike. Snowy Mespilus, as already noted, refers to the wonderful blizzard of innumerable tiny petals that grace the trees and then the ground beneath the trees as Spring progresses. “Mespilus” are the Medlars, further members of the Rose family, and ones to which the Amelachiers bore a resemblance in the eyes of the first Europeans to document the new North American flora. The names “shadbush”,” shadwood” or “shadblow” are also references to the flowering season, which coincides with the arrival of the Shad – a fish that formed a staple food for many of those same early settlers.

The flowers are only one of the appeals of the Amelanchiers, however and “serviceberry” and “juneberry” are further much-used common names. These, of course, refer to the fruit – a red-purple berry that eventually matures to black which was considered to resemble the berries of the wild European Service Tree – Sorbus domestica. The fruit are edible, and in the best varieties, quite delicious, which characteristic gives rise to yet more common names including “sugarplum”,”wild-plum”, and “Indian pear”, again, all hinting at the importance of the plant in the lives of the early populations of  North America.

To the Cree Native Americans the plant was “misâskwatômina”, a name that was Europeanised into “saskatoon”, after which the town of Saskatoon, Saskatchewan, was named. Finally, while we’re talking names here, Amelanchier itself is derived from “amalenquièr” the Provençal name for the European species: Amelanchier ovalis, and, despite some sources that might state otherwise, the name is pronounced:  amma-LANK-ee-er, with a hard “K” sound, which perhaps becomes more obvious when seen against it’s French language counterpart.

Amelanchiers produce an abundance of flowers from a very young age, and even the tiniest specimen will pop out a handful of blooms. Within a few years all of the branches of that plant will be fully laden with blossom each Spring. Once opened the flowers are joined by the new foliage which is often flushed with bronze or copper, making for a magnificent contrast and highlighting those dazzling white flowers all the more.

So we have a tremendous Spring display followed by branches smothered by small, but highly decorative, edible fruit, but these trees have one final trick up their sleeves as the foliage can turn to glorious shades of orange and red in a good, crisp Autumn.  Amelanchiers display their autumn finery with great gusto and reliability in North America, although the colour can be patchy of even absent here in the UK, but that is entirely to do with our erratic, maritime climate rather than any failing on the part of the plants.

Virtually all Amelanchiers are capable of producing fiery autumn foliage under the right conditions.

Despite the presence of numerous selections in cultivation – the RHS Plantfinder currently lists 44 named forms – Amelanchiers are a pretty homogeneous lot, and really there is very little to choose between them. A. x grandiflora ‘Ballerina’ was selected for it’s larger flowers and is now very widely distributed. It’s a lovely plant, but we have it growing amidst 10 or so other named forms, and frankly I’m hard pushed to tell them apart from one another.  There are a few genuinely different selections however. The lovely pale-pink flowered form A. x grandiflora ‘Rubescens’, and pink-fading-to-white-flowered ‘Robin Hill’; the slender, upright growing A. alnifolia ‘Obelisk’ & similar A. canadensis ‘Rainbow Pillar’ and the much smaller growing A. rotundifolia ‘Helvetia’ and equally compact species A. stolonifera are all distinctive.

Aside from these last two, all Amelanchiers are vigorous, as well as undemanding and easy to grow in many garden situations. Depending on how they are treated and grew as young plants they can form graceful, slender trees or multi-stemmed, more-or-less globular large shrubs. The plants can eventually get quite substantial, but they retain an airy, light quality to them and the slender leaves don’t cast a great deal of shade, even in mid summer. Plants may also be pruned after flowering to retain a desired shape or keep them to a fixed size. Amelachier are tolerant of a wide range of soils, including heavy clay and even water-logging, although young plants should be mound-planted if soil is permanently wet to allow the roots to find their own way through rather than simply plunged into a soggy hole.

All parts of the plants are edible and are evidently quite appealing to a variety of browsing animals, from harmless leaf-cutter bees through to more potentially damaging rabbits and deer, so young Amelanchiers should be given some protection where appropriate. They are generally very healthy plants too, although they can suffer from fungal leaf spot, particularly if grown in sheltered areas with limited air movement. Treatment of the newly emerging foliage, together with collection of fallen leaves in autumn will keep this problem in check should it appear, and an opening up of the canopy of more congested plants will help prevent it’s re-occurrence.

If sheer flower power in early to mid Spring is your thing, then, whichever form, species, or selection you choose, you won’t find a better small tree than the Snowy Mespilus, and adding one to your garden will ensure that you’ll always have at least a little of the right kind of snow, right where you want it every March and April.
