Today, home gardeners enjoy them as easy-care bedding plants, equally at home in the vegetable garden as they are in containers or the landscape.
African marigolds (Tagetes erecta) are the tallest form, with double blooms up to 6 inches in diameter, and the shorter and smaller-flowered French marigolds (Tagetes patula) are enjoyed for their rich color blends. Finally, dainty signet marigolds (Tagetes tenuifolia) are perfect for edging and bloom the most prolifically.

The main requirement for success is good drainage, so nemesia generally do better in containers than garden beds. Otherwise, these are easy-care plants and do not need deadheading.

SALVIA, SAGE(Salvia spp. and hybrids)
In addition to the perennial and shrub forms of sage, there are several outstanding tender varieties that can be enjoyed as annuals in colder climates. All are deer resistant and drought tolerant once established, and reliably heat tolerant. These upright plants perform well in the landscape and containers.
Mealycup sage (S. farinacea) is typically blue and makes a statement in the landscape; some newer hybrids are larger and especially attractive to hummingbirds, with flowers in shades of red, orange, and pink. For an electric glow, try pineapple sage (S. elegans) with its golden-yellow leaves and fire-engine red blooms in late summer or early fall. This grows to the size of a modest shrub in a single growing season. Finally, consider leaving room for scarlet sage (S. coccinea). A perennial in its native southern range, varieties are often available as annuals in cooler climates.
Size and habit will vary with species and variety.

BOUQUET-WORTHY BLOOMS
AFRICAN DAISY(Osteospermum hybrid)
These cheerful daisies are bound to elicit a smile—and mercifully seem to be ignored by both rabbits and deer. African daisies do well in the landscape if the soil is well drained, and thrive in container gardens. Deadheading isn’t necessary since the spent blooms are quickly hidden as the plant grows.
In hotter climates, peak bloom times will be late spring and early fall, as these daisies dislike intense summer heat. In more temperate regions, you may enjoy a good display throughout the season. Cut blooms as soon as they open to use in arrangements. Single and semi-double-flowered varieties add to their value and interest.
In warmer climates, these may overwinter.
