Phacelia tanacetifolia Annual cool season cover crop.
Non-legume, fast-growing broadleaf. Excellent ability to accumulate and recycle excess Nitrates and Calcium. Bees love its blue flowers. Winter kills at 20°F. When planted at high seeding rates, it provides good weed suppression and the succulent tissue is easy to incorporate. Can be used for feed or hay in soil with low to medium Nitrogen availability.
I grew your phacelia for the first time this year in Central Wisconsin, as an annual. The bees loved it so they flew away from buckwheat! They were over-ridden by weeds because I didn't disc the soil properly, but my soil depth is only 3\", with 35 ft. of sand underneath. I have to water, of course. I did that at night so as not to disturb my girls' foraging. My patch was too small and I didn't plant enough seeds to choke out the weeds. I'm planning to improve that next year!Review by The Bees' Knees (on 8/11/13)
