No consensus exists regarding the enumeration of North American Amelanchier taxa. In eastern North America, most floras and regional treatments have roughly the corresponding number (although sometimes not the same species) as G. N. Jones (1946); though often substantial differences of opinion exist regarding circumscriptions of individual taxa. Disagreement is deeper for western North America, for which Jones had seven species and P. Landry (1975) had but one.
Identification of individual taxa can be difficult because of the variability within each species. In addition, some species have not diverged much from one another genetically.
In general, we are following the treatment in the Flora of North America[]

General Information

Amelanchier humilis is a deciduous shrub usually growing to 1.5 metres tall, exceptionally reaching 8 metres in shaded conditions, It can sucker quite freely, producing up to 50 stems and forming scattered colonies[].
The plant is often harvested from the wild for local use as a food.

Cultivation Details

Hardy to about -25°c[].
Prefers a rich loamy soil in a sunny position or semi-shade[, ] but thrives in any soil that is not too dry or water-logged[]. Grows well in heavy clay soils. Plants are often found growing on calcareous soils in the wild[].
All members of this genus have edible fruits and, whilst this is dry and uninteresting in some species, in many others it is sweet and juicy. Many of the species have potential for use in the garden as edible ornamentals. The main draw-back to this genus is that birds adore the fruit and will often completely strip a tree before it is fully ripe[].
This species produces suckers freely, forming thickets[].
Closely related to Amelanchier stolonifera[, ].
Hybridizes with Amelanchier spicata, Amelanchier arborea and Amelanchier bartramiana[].
Grafting onto seedlings of Amelanchier lamarckii or Sorbus aucuparia is sometimes practised in order to avoid the potential problem of hybridizing[].

Edible Uses

Edible fruit - raw or cooked[, , ]. Sweet[]. A very pleasant flavour, the fruit is juicy with a hint of apple in the taste and contains a few small seeds at the centre[]. The almost black fruit is 6 - 8mm in diameter[]. The fruit is rich in iron and copper[].

Medicinal

Propagation

Seed - it is best harvested 'green', when the seed is fully formed but before the seed coat has hardened, and then sown immediately in pots outdoors or in a cold frame. If stored seed is obtained early enough in the autumn, it can be given 4 weeks warm stratification before being left out in the winter and it should then germinate in the spring. Otherwise seed can be very slow to germinate, perhaps taking 18 months or more. When large enough to handle, prick the seedlings out into individual pots and grow them on in a sheltered outdoor position, planting them out once they are 20cm or more tall.
If there is sufficient seed it is best to sow it thinly in an outdoor seedbed[, ]. Grow the seedlings on for two years in the seedbed before planting them out into their permanent positions during the winter.
Layering in spring - takes 18 months[].
Division of suckers in late winter. The suckers need to have been growing for 2 years before you dig them up, otherwise they will not have formed roots. They can be planted out straight into their permanent positions if required.
