An annual, from the point of view of the amateur gardener, is any plant which must be replaced each year and which flowers only once in its life. Annuals generally are grown from seed. The chief advantage of annuals over perennials is their low cost. Thousands of plants can be grown from a single packet of seeds.

Annuals are also very decorative, and provide the best source of flowers for cutting. Their season of bloom is relatively long, as well. Their chief disadvantage is the late date at which they bloom. If annuals are used alone in a bed or border, a good part of the season will pass with little to show in the way of color.

Annuals are also of use as a filler between shrubs set some distance apart. This permits the shrub to grow, yet prevents too stark an appearance. The sowing of annuals, of course, depends upon the class to which they belong. The hardier flowers, such as larkspur, poppies and cornflowers, can be profitably planted in late fall. The ground preparation must be just as careful as for spring planting. Planting in fall is advantageous since it permits the flowers to get an early start the following spring. Certain other hardy annuals can be planted early in spring as soon as the ground is workable.

It is a good idea to start some of the less hardy annuals in seed pots, or in coldframes, as early as March. Otherwise, these plants cannot be set out until all danger of frost is gone. Outdoor planting of annuals in the spring follows thorough soil preparation. The seedbed must be carefully pulverized with a rake after it has been prepared and prior to planting. Eliminate all lumps.

The seeds are sown broadcast in the patch selected, and then are lightly covered with soil. The soil may be gently tamped after the covering is completed. The patch should be identified with a stake and some sort of sign. Flower seeds are best planted near the surface. In no case should they be sown more than 1 inch deep. The seeds of larger plants which have a strong growth, such as sunflowers, can be planted in hills spaced from 2 to 4 feet apart.
