Why grow your own

Growing slow bolt arugula from seed is one of the most rewarding ways to skip the pesticide-treated, ultra-shipped produce in conventional grocery stores. You control the soil, the water, and the timing, and at the end of the season you can save seed to plant again next year. That's how gardens used to work.

Our packets are naturally sourced, non-GMO, and hand-packed here in Amador County so they arrive ready to plant.
