I'm at an urban permaculture farm in Roanoke, VA and writing to see if anyone has experience with or knowledge about growing Chipilin (Crotalaria longirostrata) as an annual in temperate climates. I learned about this plant in Guatemala, where it is used as a perennial nitrogen fixer and edible shrub. Also a traditional ingredient in Pupusas from El Salvador! It's been pretty hard for me to find info on growing this, the best I've found is: http://www.growingmagazine.com/print-5120.aspx
I have some heathy, young chipilin plants but am not sure the best way to grow this as an annual, can anyone help me out?
A number of questions:
How should I care for it besides putting it in decent soil and keeping it well-watered?
Could it become invasive?
Why is seed so expensive?
Will I be able to save seed in USDA zone 7?
