A New Dahlia

Our yard is filled with Dahlias - and they are coming up in the strangest places! On my last trip to Tacoma, however, my mom had an extra dahlia bulb and I just couldn't resist. It's a Tahoma Frills variety -- and it should bloom white in 6-8" wide blossoms! Here's the 'before' picture. It's the very, very little green sprout on the left of the pot! (don't worry - it's pretty much impossible to see right now)
