Cow-parsnip by the Upper Bluffs: August 2021

Cow-parsnip (which can grow to 10 feet in height) is found all over Ontario in moist meadows, thickets and forests.

Lately I have been seeing signs warning about touching the plant. Cow-parsnip is not toxic, but the juice can cause contact dermatitis in sensitive individuals.

Here is how it looked this morning in a field by the Upper Bluffs.

Cow-parsnip is a close relative of the much more deadly Giant Hogweed.

NATURE POETRY

this is the garden: colours come and go,
frail azures fluttering from night’s outer wing
strong silent greens serenely lingering,
absolute lights like baths of golden snow.                        – e e cummings (1894–1962)
