The distribution and planting of state‐listed endangered and threatened plants is outlawed in most states of the United States, yet listed species are commonly used in landscaping and restorations. There is a need to re‐examine policy regarding planting and propagation of endangered and threatened plants outside of planned recovery efforts. Potential advantages associated with increased outplanting of rare species include (1) improved public education and relations; (2) demographic security derived from creation of new populations; (3) provision of new, appropriate gene‐flow opportunities; (4) applied research opportunities; and (5) ability to regulate a currently uncontrolled activity. Potential disadvantages are (1) confusion of natural and planted populations; (2) bureaucratic problems with protection of planted populations; (3) potential far inappropriate gene flow between natural and planted populations causing outbreeding depression and loss of genetic purity of natural populations; and (4) extension of the natural geographic and ecological range of the species. Policies, regulations, and nursery practices exist that would maximize the potential advantages and minimize the risks associated with the distribution of endangered and threatened plants. Policy considerations discussed include selection of appropriate species, production of appropriate and high‐quality genetic stock, and regulation of outplanting programs. I weigh the risks and benefits of a program that would allow the general public access to some state‐listed plants for natural landscaping. I conclude that a less restrictive but enforceable set of policies and regulations may be preferable to the status quo.
