* Annual - Grows blooms and seeds in one growing season, usually dies in winter. Perennial (Hardy) - Lives and blooms from more than one growing season.


Ageratum Remove spent blooms to prolong flowering. Keep well-watered in hot, dry weather.
Alyssum, Sweet Shear plants back lightly to promote longer blooming period.
Aster To minimize the possibility of Aster Wilt, plant in a different part of your garden each year.
Begonia Bronze-leaved varieties do particularly well in sun. Keep foliage dry, provide good air circulation around plants.
Chrysanthemum Can also be set out as plants or rooted cuttings. Fertilize heavily. To promote bushy growth and more flowers, pinch out tips several times, up to July 15. Divide in spring.
Coleus Pinch off flower spikes to promote growth and attractive appearance.
Crape Myrtle Started indoors in March from seeds, will bloom in late July. Also available as plants. Hardy in South; in North, bring plants indoors over winter.
Dahlia Blooms first year from seed. Also available as tuberous roots that should be planted 6 inches deep after danger of spring frost. Taller varieties may need staking.
Daylily In South, seed sown in late summer will bloom following year — takes longer in the North. Most commonly grown from plants. Exceptionally easy to grow, weedproof and trouble free.
Delphinium Feed heavily. After blooming, cut back flowering stalks at base to induce fall reblooms.
Gerbera Seed started in January will bloom in June. Grow in full sun, providing ample moisture. North of Washington, D.C., pot up in fall and grow in a cool sunny window over winter.
Geranium Geranium seeds may germinate irregularly, so do not transplant from tray until germination is complete. Drench seedlings with approved fungicide.
Hollyhock Some bloom from seed the first year, others should be started in August for bloom the following season. Young plants perform best; keep a new supply coming from seed.
Impatiens One of the best of all annuals for shade. Starts blooming in 3 months from seed. Pinch back once or twice before setting out, thus promoting compact, bushy growth.
Lisianthus Move to full, bright light and 80-85° temperature after the small seedlings first become visible.
Marigold Plant overly tall or leggy seedlings deep,so they will root along the stems. Remove spent flowers for appearance and to promote more bloom. Easy!
Pansy Prepare planting site deeply, adding humus. Cool, shady, moist soil gives best results.
Pardancanda Will grow, even under adverse conditions. Use winter mulch north of Zone 7.
Portulaca May be started indoors or sown in the garden.
Primula Hardy sorts also available as plants. Prefer moist soil, high in humus.
Salvia Use reds for concentrated bright color; pastel shades do well in light shade. Drench seedlings with approved fungicide to prevent damping off.
Snapdragon Pinch back after blooming to promote a second flush of bloom.
Strawflower To preserve, cut when showing good color and hang upside down, where air circulation is good.
Sunflower Easily grown in sun. Large kinds provide edible seed for people or birds.
Vinca Periwinkles are excellent for foliage effect and flowers from June to frost. Both creeping and dwarf upright types are available.
Zinnia Plant where good air circulation is available.
