Are you asking about Amelanchier canadensis?

Yes

Growth rates are impacted by soil type. I have Autumn Brilliance and it grow slowly for me in a well drained sandy loam - more sand than anything though. Its also slightly alkaline which also impacts its growth rate.

Thank you whaas_5a. That answers my question so I will plant another Canadian Serviceberry (Amelanchier canadensis).

[That is interesting about the type of soil. I have several Carpinus Carolinia. All the sources I have found say that they are slow growers but I find that they aren't. They are not fast, but certainly not slow.

1 ft. per year is quite low on the scale of tree growth rates. Some trees - and this includes the range of cold climate kinds - may grow multiple feet per year. Elms and willows for instance. With there being all these others that fall between the two ends of the spread.

Of course compared to towering shades trees its slow but to comparative small scale trees it’s a fast grower. It can achieve 2’ when young.

This species can outpace bald cypress, american beech and buckeye around here during the young years

Amelanchier canadensis is characteristic of "damp soils" (below) in nature so maybe yours are finding the planting site a bit on the dry side, would grow faster with more moisture.
