Using groundcovers in sea coast gardens can give you easy low-maintenance color. I love to use ground-covering plants in masses because the waves of color kind of echo the broad waves of the ocean.
Planting groundcovers also avoids a lot of the issues found when planting individual shrubs or trees. When planted in masses, the wind blows up and over the groundcovers rather than catching the branches and constantly shaking the plants.
These plants can be used as groundcovers in the toughest of sea coast conditions:

Some other great groundcovers for the sea coast?
Arctostaphylos uva-ursi or Kinnikinnick/ Bearberry, a Pacific Northwest native
Rosmarinus prostratus or Creeping Rosemary which attracts honeybees and hummingbirds
Flower Carpet Roses, particularly the Pink or Appleblossom varieties which seem to be the most vigorous
Coleonema ‘Sunset Gold’ or Golden Breath of Heaven – the foliage has a pleasant nutmeg scent when brushed against!
