If you had to choose between Blue Bell (purple, 4" bloom supposedly) and Thomas Edison (purple, 6-8" bloom) for somewhat small bouquets, which would you pick? If, in fact, they are true to name, I picked Thomas Edison, not knowing that it was considered a "dinnerplate" dahlia. I am thinking maybe I should trade it in for the other (at my local grocery store). I am a VERY small flower grower compared with most of you, so I only have a few dahlias. Thanks! Phyl
