Many desirable species of flowering plants are annuals, which means that they are planted with seeds in the spring and allowed to germinate and grow until the end of the year. Alyssums are a good example and even have the habit of dropping seed as they flower and grow. As nifty as this can be, it pays to find our own seed because wild pollination might not yield the same results for all species. A variety of annual flower seeds can be found online, and these have the habit of being more robust than more generic seed.

For more vigorous growth and healthier flowers, find the better brands that are offered by the highest-quality growers. Annuals are a different deal than perennials because they have to do all their growing in a year. If the seed is great stock to begin with, the result will be abundance even with average soil.
