Rattlesnake Root at the Guild Inn: September 2021

Ontario’s only remaining rattlesnake, the Massasauga Rattlesnake, is almost extinct and found only in a few regions of eastern and western Georgian Bay.

At one time, however, it was found in many parts of Ontario. One plant in our area has the name Rattlesnake Root because the root and milk inside were formerly used to cure snakebites.

I found it in flower today in the wet woods near the Guild Inn.

One of those “confusing fall warblers”, the whitish eyering, wing bars, yellow underparts and some black striping identify this as a Magnolia Warbler.

Hi Miles,

Thought you might be interested in this Toronto Zoo’s breeding program. 


So we grew together,
Like to a double cherry, seeming parted,
But yet an union in partition,
Two lovely berries moulded on one stem. – Shakespeare

    This is a remarkable place, with its monuments, statuary, woods, bluffs, lake–it has it all! Such beautiful botany, and a wonderful Warbler I couldn’t identify. Thanks, Miles!
