Amelanchier alnifolia (Saskatoon Serviceberry)


Michael's Opinion

A class small tree or large shrub that is often planted in poor locations and is butchered in the large urban landscapes around shopping malls, and such, not rendering its superb reputation as a native landscape plant any benefit. An excellent edge species to humanise the scale of large landscapes. I personally prefer the multi stemmed plants. This species is a little coarser than my first choice, A. canadensis.
