Wildlife Value

Berries

Seeds

Nectar for hummingbirds

Nectar for butterflies

Host for insect larvae

Thickets and shelter

Thorny or protective cover

Birds: During winter months, insect-eating birds such as chickadees and bushtits forage for insects in the shrub. The seeds persist through the winter. Dense branches provide songbirds with shelter and cover.
Insects: Swallowtail, brown elfin, Lorquins admiral, and spring azure butterflies browse on the foliage. The nectar may be harvested by mature swallowtail butterflies. Many species of insects live in the dense structure of oceanspray.
Mammals: Deer and elk browse the foliage.

Ethnobotanical Uses and Other Facts

Material Uses: The wood of oceanspray is hard and durable. It was used to make digging sticks, spears, harpoon shafts, bows, and arrows by nearly all coastal groups including the Salish, Halqemeylem, Squamish, Sechelt, and Kwakwakawakw. The Saanich and Cowichan used the wood to make salmon-barbequing sticks, inner bark scrapers, halibut hooks, cattail mat needles, and more recently knitting needles. Oceanspray pegs were used in construction before the use of nails. The Nlakapamux made armor plating from the hard oceanspray wood. The Squaxin used the wood to make canoe paddles.
Medicinal Uses: The Saanich and Stlatlimx boiled the fruiting clusters of the oceanspray to make an infusion that was drank to cure diarrhea, measles, chickenpox. This infusion was also used as a blood tonic. The Lummi applied the leaves to sore lips and feet.
Landscape Uses: Nice background plant.
