When raised for growing in gardens or as plants for home decoration, many seed-raised plants grown in temperate climates have a different growth pattern or life cycle from their natural one. For example, Lobelia erinus (Edging Lobelia) is a half-hardy perennial usually grown as a half-hardy annual; Mirabilis jalapa (Marvel of Peru) is a perennial grown as a half-hardy annual; and Impatiens walleriana (Busy Lizzie) is a greenhouse perennial invariably grown as a half-hardy annual. Bellis perennis (Daisy) and Dianthus barbatus (Sweet William) are perennials grown as biennials. The purpose of changing the cycle of growth of such plants is to produce many plants at the same time, in the easiest way possible.
