Annual

A plant that completes its life cycle within one year. This means that it germinates, grows and develops, flowers and then produces seeds which then go on to germinate in the subsequent year. Examples of annual plants include:
• Ageratum houstonianum
• African Marigold (Tagetes erecta)
• French Marigold (Tagetes patula)
• Petunia
• Nicotiana langsdorfii
• Hare's tail grass (Lagurus ovatus)
• Love in a Mist (Nigella damascena)
• Annual Phlox (Phlox drummondii)
• Some plants are short lived perennials, but may be grown and treated as annual, e.g. Snapdragon (Antirrhinum majus), Nemesia.
