Mustard
Brassica juncea
Zones 3–11
Growing
Sow your mustard seeds directly into the garden or a container once the soil has warmed, as this annual thrives in the cool season and can even withstand light frost. Because this plant grows as a single upright stem, it is easy to manage in small spaces or raised beds. To get the most out of your harvest, aim for a soil pH between 6.0 and 7.5 and ensure your planting site provides regular watering and well-draining soil that is not waterlogged.
When you are ready to eat, harvest the leaves, stems, or seeds, as all parts of the plant are edible. The greens and seeds are notably more pungent and spicy than varieties like kale or broccoli, making them a bold addition to mixed green dishes or a flavorful base for condiments. If you are interested in preserving the harvest, you can pickle the greens, freeze them after blanching, or even dry the seeds. For the best quality, keep your harvested greens unwashed until you are ready to use them.
