What are some groundcover herbaceous perennials that would be salt tolerant?
For salt tolerance of trees and shrubs, consult UVM OH leaflet 56, http://ctr.uvm.edu/ctr/oh/oh56.htm Some herbaceous perennial groundcover choices here would be bearberry, blue lyme grass, and wormwood. Many can be massed for a groundcover effect, including low catmints and salvias, blue fescue grass, sea thrift, some Allwood dianthus (such as ‘Helen’), some daylilies such as ‘Stella de Oro’, sea lavender, sedum ‘Autumn Joy’, and for warmer climates lilyturf.
