Good news, there's an app for that. I've been fantasizing about such an app since the dawn of smartphones, and Picture This delivers the goods for clueless home gardeners everywhere.

The app, which is available for Android and iPhone, lets you take a picture of a plant, and within seconds the app identifies it. It also displays information about the plant, its background, information on how it grows and if it's poisonous.

My yard is a mix of wildflowers, weeds, and perennials planted on purpose by the previous owners. An app like this is great for figuring out just what is it you do have in your garden.

The app is free for a trial period, but then requires a weekly or monthly subscription.
