We never planted these foxglove - they are "volunteers"... seed carried on the wind from an uphill neighbor's garden.
In the fall we have to pull them out like weeds, but do not feed them to the chickens, because of the digitalis.
We do our best to find them new homes in other gardens, and not toss them into the green compost bin, which is always a last resort.
And don't they look great poking up through the golden cotinus!
