Lacy scorpion-weed - Phacelia
This species quickly covers the ground with large mats of cut foliage reminiscent of tansy, and offers clusters of lavender-blue flowers for several months, which are extremely attractive to moths.
Phacelia fixes mineral nitrogen and returns it to the following crop in the form of assimilable nitrogen. Its fine, dense root system quickly suffocates weeds - especially quackgrass.

Sow directly in the ground, broadcast or in rows, in clean soil, at a density of 1 to 2 g/m2.
For use as a green manure, it should be mowed before it goes to seed to prevent it from reseeding naturally. Phacelia easily withstands temperatures ranging from -5° to -10°, but is sensitive to drought.

Phacelia is not only one of the most mellifluous cultivated plants, but also an excellent green manure. It offers many advantages: rapid growth, high biomass production, dense and branched root system, etc. It's also a very interesting flower to include in a permanent flower meadow, as it reseeds naturally and, once established, will remain in place for many years!
