What’s not to love about the vibrantly green, tree-shaped florets of broccoli seeds? A cruciferous vegetable in the same family as kale and cabbage, broccoli is a hardy cool-season vegetable bursting with nutrition. Throw out any preconceived notions of bland broccoli from the supermarket, and give one of our eight flavorful heirloom varieties a chance. Choose between classic head types like Waltham 29 or the fractile-shaped Romanesco, or try out Broccoli-Raab Spring Rapini for a fun variation. Sow bulk broccoli seeds in both spring and fall for twin harvests.
