Alfalfa
Medicago sativa
Alfalfa is a deep-rooted, fast-growing perennial legume that thrives in full sun with well-drained, neutral to alkaline soil and fixes atmospheric nitrogen, improving soil fertility over time. It is highly drought-tolerant once established thanks to its impressive taproot system, and requires minimal watering or feeding. Harvest leaves young for nutritious sprouts and salads, or allow it to flower to attract bees and other pollinators.
