Butternut is easily recognized by its compound leaves, which are made up of 11 to 17 leaflets (each nine to 15 centimetres long) arranged in a feather-like pattern. The fruit is a large nut that contains a single seed surrounded by a light green, sticky, fuzzy husk.
Endangered
“Endangered” means the species lives in the wild in Ontario but is facing imminent extinction or extirpation.
Where it lives
In Ontario, Butternut usually grows alone or in small groups in deciduous forests. It prefers moist, well-drained soil and is often found along streams.
It is also found on well-drained gravel sites and rarely on dry rocky soil.
This species does not do well in the shade, and often grows in sunny openings and near forest edges.
