Fresh herbs and peppery arugula bring pork chops and potato salad together with a springtime feeling.

Get to know arugula flowers, an edible flower with a peppery bite, perfect for adorning all of your spring dishes.

Today we're taking a nose dive into the salad bowl with a half-dozen varieties of dark leafy greens. These plants come from a few different plant families -- arugula, kale, and collards are Brassicas, spinach and chard are in the Amaranth family, and dandelion is from the family Asteraceae -- but they share certain essential characteristics in the kitchen: all can be enjoyed raw or cooked, and they're all hardier than the fragile salad greens of spring.

This is the sixteenth in our biweekly series from Amy Pennington – urban farmer, founder of GoGo Green Garden, and author of Urban Pantry and Apartment Gardening – on how to start growing your own food, no matter how tiny your garden-to-be is.

Today: It's hard to believe, but fall is on its way. Amy tells us what to plant now for the perfect patio harvest come cold weather.
