Art of Flora teaches us a lot about the plants around us. For Halloween, get familiar with some of the pretty-but-deadly ones.

What we love: Complete puzzles for 10 new plants such as foxglove, which is deadly for all mammals while also used to treat human heart conditions, or doll’s-eyes, which is toxic and can be deadly to humans but completely safe for birds and insects.

Don’t miss: Twenty per cent of all proceeds from Art of Flora are donated to nature preservation efforts.
