Here's an excerpt of Plants vs. Zombies 2 Question and Answer- Customer Care from Popcap blog.

While in the original Plants vs. Zombies you would have had to plant this over top of the standard Sunflower, in Plants vs. Zombies 2, it is a complete plant all by itself! You can plant a Twin Sunflower directly on any unoccupied square.
Granted, you may need to take the standard Sunflower along on some levels in order to get enough sun to plant a Twin Sunflower. . . but not on all levels (some Brain Buster levels start you off with Sunflowers already), and not if you’re making creative use of some of the optional items like Sun Bonus Upgrades and Plant Food! Consider the possibilities! The standalone Twin Sunflower actually allows you to save a seed slot without sacrificing sun power.

But PVZ players would rather find out when other platforms will get their version of the game (Android, PC and Mac). That is all!
Thousands of fans were hoping that Popcap Games would have something to say about their Plants vs. Zombies 2 Google Play launch plans during PAX Prime last weekend, but the fifth annual Penny Arcade video game convention in Seattle has come and gone without any such announcement. The up-and-coming GameStop Expo also passed without any word on the Plants vs. Zombies 2 Google Play launch, leaving fans to hope that Popcap Games could be planning an announcement during the traditionally console/mobile-focused Tokyo Game Show (Sept. 21-22).
