All About Kale

Happy Kale Day! National Kale Day is celebrated the first Wednesday in October. LAUSD Food Services will be providing their middle schools with a kale recipe but you too can celebrate! Read below to learn more about this superfood and find recipes and resources to celebrate every day like it’s Kale Day!


Kale, Brassica oleracea, has seen a surge in popularity in recent times but it does in fact have a long history. It was consumed by people living in the Mediterranean and Asia Minor (present day Turkey) since at least 2000 BC. Kale made it’s way westward through England and eventually the New World. In 1542, the first brassica was planted in Canada. By the 1700s brassicas were widespread in the colonies.

There are many types of kale, though we often provide Learning Gardens with curly kale, lacinato, and red Russian. This year we are providing Siberian kale which has more tender leaves than curly kale.
