National Plant Germplasm System

For those unaware of its existence, I wanted to point out a resource I have found very valuable: the National Plant Germplasm System, at http://www.ars-grin.gov/npgs/index.html

NPGS preserves genetic diversity of plants, and makes germplasm (ie, seeds and cuttings) available to scientists, organizations, and individuals conducting research. I have requested various rare seeds and cuttings over the last two years to integrate various plants into our food forest and find out what works well together. I plan to request many more species this year, some of which I've only been able to find at NPGS!
