In a 2020 study of salt in irrigation water (https://journals.ashs.org/hortsci/view/journals/hortsci/55/7/article-p1119.xml), this species was found to be moderately tolerants of salt (at concentrations considered to be brackish) in the rooting medium.  Plant survival and health were better at lower salt concentrations.  Salt wind tolerance was based on known occurrences of this plant in near-shore, open areas near the east coast of Florida. Informal garden planting.

Its more upland relative, Nyssa sylvatica, grows well in sandy uplands and is highly similar in appearance. Somewhat slow growing. Grows naturally in swamps and best planted in moist areas. For moist settings, it is appropriate both as a shade tree and as a fall-color specimen tree in those parts of the state that get good fall cooling.

Wildflower garden, most species prefer relatively moist conditions.

Most plants sold as P. obtusifolia are from tropical American stock; local sources are recommended both to protect the genome and to enhance your likelihood of success. It is listed as Endangered by the state of Florida. Groundcover.

Wildflower garden. This is a small but pretty little plant. Grow it in a moist wildflower garden.

In mild areas, plants sometimes persist through the winter and will bloom again. They need to be cut way back or they will not be attractive. Wildflower gardens and meadows.

This is a wetland plant. It is rarely grown, but it has potential in appropriate sites. Background screen in wet garden
