Discussion

Flowers of Elaeagnus pungens have a sweet gardenia-like fragrance that attracts butterflies and its fruits are favored by birds. It forms clumps that are broader than tall, with canes that often grow into neighboring shrubs and vines. Plants grow prolifically and can be propagated by cuttings. It has become invasive in some areas. The Florida Exotic Pest Plant Council has placed it in the category of invasive exotics that have increased in abundance or frequency but have not yet altered Florida plant communities.

Cultivars vary in growth form and color: ‘Fruitlandii’ forms large bluish green mounds; ‘Maculata’ has large leaves with bright yellow variegations and blotches; and ‘Marginata’ has leaves with silvery-white margins. The leaves are distinctive with their leathery texture, wavy margins, and thick petioles. Most cultivars are thornless. Because these plants form large, vigorous clones, they are not recommended for small properties (M. A. Dirr 2009).
