Triglochin maritima

Seaside arrow-grass

This herbaceous perennial grows 2-3’ tall and works well in a pond setting in the native garden.  The purple spike of flowers emerges summer through fall.

After bloom, the long, ropey seed head catches your attention and adds an attractive vertical element in the landscape.

Found in brackish and saltwater marshes, this plant tolerates salty soils.
