Annual

Annual: a plant that completes its life in one growing season. It germinates, grows, flowers, sets seed and dies within a year.

• Examples: zinnias, marigolds, cosmos and painted sage.
• Grown as annuals: many plants sold as annuals, such as pentas, mandevilla, petunias and tomatoes, are really tender perennials. They survive winter only in frost-free areas (about zones 10 and 11) and are replanted each year elsewhere. Their profiles give the zone where they are perennial.
• Care: replant each year, or let self-sowing types reseed.
