The soil conservation service has plant material centers (new varieties and
species) across the USA. You can contact your local SCS and they will give you
the address for the center closest to you. The Plant Material Centers (PMC) will ship out small quantities (<0.5 lbs) of certified, pest free seed to any
educational institute (including your local K-12). They will provide planting
instruction if requested

Good Luck
