Annuals

Plants of this description arrive at maturity, bloom, produce seed, and die in one season.

Hardy Flowers

The seed should be sown thinly in the open borders during March, April, or May in fine soil, covering slightly with well-prepared mould—very small seeds require merely a dusting over them. When the plants are large enough to handle, thin them out boldly, to allow them to develop their true character. By this means strong and sturdy plants are produced and their flowering properties are enhanced. Many of the hardy annuals may be sown in August and September for spring flowering, and require little or no protection from frost.

Half-Hardy Flowers

These are best sown in boxes 2 or 3 in. deep during February and March, and placed on a slight hotbed, or in a greenhouse at a temperature of about 60 degrees. The box should be nearly filled with equal parts of good garden soil and coarse silver sand, thoroughly mixed, and have holes at the bottom for drainage.

Scatter the seeds thinly and evenly over the soil and cover very lightly. Very small seeds, such as lobelia and musk, should not be covered by earth, but a sheet of glass over the box is beneficial, as it keeps the moisture from evaporating too quickly.

Should watering become necessary, care must be taken that the seeds are not washed out. As soon as the young plants appear, remove the glass and place them near the light, where gentle ventilation can be given them to prevent long and straggly growth. Harden off gradually, but do not plant out until the weather is favourable. Seed may also be sown in a cold frame in April, or in the open border during May; or the plants may be raised in the windows of the sitting-room.

Tender Flowers

These must be sown on a hotbed, or in rather stronger heat than is necessary for half-hardy descriptions. As soon as they are large enough to be shifted, prick them off into small pots, gradually potting them on into larger sizes until the flowering size is reached.
