PopCap has a tendency of giving powerful, useful and all around strong abilities to Premium plants but only if they are real premiums. If they are gemiums, sure they are stronger and more useful than free plants but compared to the real premiums they are not that powerful or useful as some kind of factor always plays that makes them the underdog compared to real premiums. Not one single premium (both real and gemium) plant proves this theory otherwise.

The gist: Premiums > Gemiums > Free

So going by this pattern, if they make Pumpkin and Umbreall Leaf real premiums, THEN they will be useful (or even more useful than the first game) for us.
