From our walk the other day there was this seven-foot tall plant.
Silphium laciniatum - the Compass plant - is a member of the aster family and a perennial native.
It's the
tallest of plants found in the North American prairie and also happen
to have the longest of tap roots - essentially making it impossible
to transplant.
The name of this flowering plant
derives from the leaves which - upon close examination - line-up
north south in order to maximize exposure to available sunlight.
The
finches love the seeds produced by the flowers and if you collect the
sap you can make a suitable chewing gum from it.
