It is a native azalea. Is it fragrant? Probably it is the Piedmont azalea, Rhododendron canescens. Very nice plant and worth keeping. It is really considered a shrub.

garvinw, if you don't know your USDA plant hardiness zone, you can put your zip code here and find out which zone you're in: http://planthardiness.ars.usda.gov/PHZMWeb/

Jatropha of some type. Definitely a tropical. Depending on your location it might be hardy. Dave Milwaukee

There you go with that amazing eyesight again, floral!! I looked but did not see the purple blotches (typically very pronounced) and the fact that hemlock is not normally found in a cultivated garden (while anthriscus is) lead me to that ID. Since both are WA state noxious weeds, either/both need to come out :-) And it's only poisonous if you eat it :-) But I'd certainly make sure I washed well before dinner!
