- Most annuals are started indoors or in greenhouses in late winter or early spring. But when spring frosts are over, plants such as zinnias, nasturtiums, and cosmos can be sown directly in the garden for a summer full of flowers.
Annuals bloom the first year they are planted.

- In colder climates, tender perennials such as alstroemeria, wax begonia, and some species of impatiens will behave like annuals and must be cultivated as such. These same plants, however, will grow as perennials in their native hot climates.
- Biennials like cup and saucer, some foxgloves, and some hollyhocks produce greenery the first year only. During the second year of growth, they flower and set seed destined to become the next generation. If you allow plants to self-sow for at least two years, you will have a steady supply of blooming plants.
