Bloomin' Flower Cards

Most greeting cards you receive are entertaining for five or ten seconds at most. You open them, you read them, then you display them on the counter because you feel some sort of obligation to the sender to leave their card standing around your house for a couple weeks. Bloomin' Flower Cards, however, are different. These cards are made from biodegradable, recycled paper with a mix of flower seeds embedded in it. After you read them, you can actually plant the entire card, and as the paper breaks down, it acts as mulch for the seeds, causing them to grow into beautiful flowers! $4.50 USD. (Via Treehugger.)
