Annuals for Sun
Flowering annual plants bloom from spring to fall. They don’t overwinter, but the reward of low maintenance continuous color is worth the effort of planting out in May. This list includes annuals bred for easy maintenance and to bloom through the heat of summer. Some will benefit from weekly removal of faded blossoms (“dead‐heading”) or shearing mid‐season to stimulate blooming. Read the labels on transplants available in your garden center to verify the identity of plants and for care instructions. Prepare the soil for annuals as you would for a vegetable garden. The same steps apply. → See Growing Tips 18 Plan a Vegetable Garden.

Keep It Simple
- Combine contrasting colors for dramatic visual effect. Multi‐colored foliage plants will tie everything together! Include tall plants for architectural interest.
- Plant sturdy, well‐grown young plants after the last frost in your area.
- Space according to directions on the label. Plants should grow to touch each other to discourage weeds.
- Mulch, then water with care throughout the season, as necessary. → See Growing Tips 6 Watering New Plantings.
