How To Grow Sainfoin in The Garden
Sainfoin is reputed to attract 10 times more bees than white dutch clover, so be prepared for honey bees to favour it above just about anything else blooming at the same time. If you have plants that require pollination it might be best to plant sainfoin in rotation so that its blooms are not competing with the plants that require the pollination.
Hardy to zone 7, Sainfoin seed is often expensive but once established, perennial stands can be long-lived. Though it resists pests and tolerates drought, it will not survive competition with weeds and so should be cultivated in well-drained, nonacidic soils, in clean, firm, and uniform seedbeds. Avoid sensitive wild habitats. Plant in April-May, and Sainfoin will bloom for nearly two full weeks.
