'Sunn Hemp' cover crop

Except for my Old Roses, I am usually a food crops man. But I am enamored with the lovely FRAGRANT blooms of this selected form of Crotalaria lutea (?) grown as a soil nitrifier and nematode suppressant. I have just a few plants but anticipate a lot of seeds so I can grow it in masses next year both to improve my soil and for the beauty. A stunning 8 footer out front was snapped in half by winds about 10 days ago. The sweet perfume stuns people! The blooms last for days in a bouquet.  John
