Description, Ancompletes its whole cycle of life, including the production of and , within one year, and then dies. A hardy is, in addition, sufficiently resistant to cold to be sown outdoors without protection in the spring. Some hardy can also be sown outdoors in the autumn and wintered without protection, but this does not apply to all.
Soil and Situation. Hardyare extremely adaptable and there are few soils or places in which they will not grow. They prefer soils that are well drained and positions that are open and sunny, but godetias do tolerably well in shade also. Little preparation is required, beyond thorough forking to prepare a fine seed bed. Manure as a rule does more harm than good, tending to produce at the expense of flowers.
Sowing. are to flower. Some seedlings may be transplanted elsewhere later on if overcrowded, but the majority are left undisturbed. Taprooted annuals, such as godetias, eschscholzias, and Shirley poppies, do not transplant well. Seed may be sown broadcast or in drills, and should be covered very lightly with finely broken soil. Water if the soil is dry, not otherwise. Germination takes from one to three weeks according to variety and weather.may be sown at any time from March till May and, in the case of particularly hardy varieties, again in early September. September sown plants will winter without thinning outdoors and start to flower in June the following year. March and April sown annuals flower from July to September, while those sown in May flower from August to October. are sown where the plants
Thinning. Ifcome up too thickly, they must be thinned as soon as they can be handled, except autumn-sown annuals, which are not thinned until the following spring. Small varieties should be thinned to 4 or 5 in. apart, kinds of medium growth to 8 to 12 in. and tall varieties to 18 in. or more.
Culture. Faded flowers should be removed before seed is formed unless it is intended to save some seed for the following year. If it is desired to save seed, a few good plants should be marked for the purpose early in the summer and all flowers retained. The seed pods are cut with a length ofas soon as they turn yellow and start to split open or, with daisy-type flowers, as soon as the heads turn yellow and show signs of shedding their . Ripening should be completed in clean, paper-lined trays in a sunny window or . Different varieties of the same kind of annual, e.g. different colours of eschscholzias, cross readily and unless special precautions are taken seed will be mixed, i.e. the seedlings will produce flowers of many different colours.
Feeding is usually unnecessary. The only other routine measure is to keep beds free of weeds, by hoeing until the plants cover the ground, and then by hand weeding.
