Native Evergreen Plants in Oklahoma

Native shrubs, groundcovers, and ferns that hold their leaves through winter for year-round green, screening, and cover. Oklahoma sits in a landscape of Cross Timbers & mixedgrass prairie, and the natives that thrive here are the ones built for its continental, hot summers character. The list below — led by Foamflower and Crossvine — is filtered to species genuinely native to Oklahoma and the wider flora of the Great Plains and hardy through zones 6–8. Evergreen natives carry the garden through the bare months, giving structure, privacy, and winter shelter for birds when the deciduous plants have dropped their leaves. Site broadleaf evergreens out of harsh winter wind and afternoon sun to prevent leaf scorch, and water them deeply going into a dry fall so they enter winter fully charged.
