Most of the species are xerophytes (found in dry habitats); several are also halophytes, tolerating high levels of soil salinity. The Elaeagnaceae often harbor nitrogen-fixing actinomycetes of the genus Frankia in root nodules, making them useful for soil reclamation. This characteristic, together with their production of plentiful seeds, often results in the Elaeagnaceae being regarded as weeds. The stems and leaves are covered with silvery brown or golden hairs which are either peltate or scaly. Shepherdia and Hippophae are unisexual, the female and male borne on different plants (dioecious). There are no petals, the perianth comprising a single......read more on Wikipedia.
