Does your sweetheart have a black thumb like no other? Want to avoid the symbolism of romantic flowers that shrivel up after just a few days? Or do you just not want to spend $120 on roses? No matter your reasons, the Flip Flap solar-powered plant ($38), which will gently wave its leaves when placed in sunlight, awaits. Given the pesticides and transport costs involved in buying real flowers, the Flip Flap might even be a relatively green option, since some of the profits go towards wind power development. And even if you have no intention of buying an electric houseplant, it's worth clicking over just to read the ad copy.
