Toronto native plants starting with A: Acalypha rhomboidea to Aureolaria virginica

Above: Asclepias tuberosa (butterfly weed).

(Updated November 29, 2009).

It's exciting to see how many possibilities for native plant garderners there are in Toronto (something you'd never guess from the average Toronto plant seller, unfortunately.) I've put a link to the relevant entries in this blog where available. I have tried to be as accurate as possible but I'm no expert so any corrections to this list would be appreciated!
