Hardy sea grasses grow alongside delicate blossoms in this bayside garden.
Cineraria: Perfect for cool, shady gardens, this annual comes in a variety of colors―from pinks and blues to white and purples―often with contrasting centers.
Strawberry geranium: This flowering plant expands from runners to act as groundcover in areas that don't get a hard freeze. "Their airy flowers lend lightness and contrast to the perennial beds," Kay says.
Daylilies: Dividing clumps regularly will keep these flowering plants (which happily grow in less sun than their name indicates) healthy and prolific. Available in vibrant yellows and oranges and soft whites and melons, there's a daylily for every garden scheme.
