Spring gardening means it's time to re-evaluate your planting beds. During the past year, your self-sowing perennials and annuals have probably dropped seeds and multiplied, leaving you with new seedlings. Transplant these seedlings to bare parts of the garden, and you'll achieve not only balance but also variety in your beds.
If you don't recognize a seedling immediately, don't dig it out; wait until it matures before deciding where to move it. In Martha's previous Westport garden, she found several self-sowing perennials and annuals (listed below) to fill the bare areas.
Perennial Shasta daisies (Leucanthemum x. superbum) are beautiful white flowers with yellow eyes. They have an unusually long bloom season -- early summer through fall -- and are great for flower arrangements.
Forget-me-nots (Myosotis), which do best when the seedlings are thinned, produce delicate blue blooms from late spring to early summer. They thrive in moist soil, and prefer shade. Use them as ground cover for planting under ferns.
Love-in-a-mists (Nigella damascena) are feathery foliaged annuals with cornflower-blue petals, and purple and chartreuse seedpods. They bloom all summer.
