I don’t think these are either choke or pin cherries.
so what type of cherries/berries are these?
the bush is about 4 feet high, the berries came out in late August.
these pics were taken in Sept.
the location is Georgian Bay, close to Honey Harbour.
thx for your help!
Excellent photos, showing habitat, leaves, as well as berries. You are correct, these are not of the Prunus or cherry family. This lovely native shrub is known as winterberry (Ilex verticillata). It is of the holly family, whereby a male and a female plant are needed to produce the spectacular fruit. As shown in your photo, the shrub is often found adjacent to water, or in riparian zones along creeks and rivers.
The leaves are considered toxic, but not deadly. The flowers come out in late spring, but are not showy. It can withstand partial shade to sun, prefers moist soil, and is salt tolerant and deer resistant. The fruit is eaten by birds. It is a recommended plant for gardens, as it is native throughout eastern Canada.
