Free plant cuttings (and other propagation materials) can be obtained from the U.S. government

Germplasm Distribution Policies & Procedures

It is the policy of the National Plant Germplasm System (NPGS) to provide small quantities of available germplasm to research and educational isntitutions for research, testing and scientific breeding efforts that require genetic diversity or specific genetic standards.

Almost all plant material from the Davis gene bank is distributed as cuttings and deadlines for orders are those appropriate for such cuttings. These cuttings must be rooted or grafted/budded to produce a plant. Material of Juglans, Pistacia, Diospyros and most Prunus are very difficult to root and the recipient must obtain appropriate rootstocks prior to receipt of scion cuttings.

As of 2017, most of the requested by the public are refused: Federally funded agricultural gene banks work to safeguard crop diversity and provide seeds and cuttings for research, breeding, and education. But too many public requests are hindering their work. More info is here:
