All flowers grew wild originally, but over the centuries gardeners have adapted flowers for the garden - selecting seeds and grafting plants together to bring out chosen qualities, such as red blooms or straight stems. There are now over a million kinds of garden flower. But many wild flowers are becoming rare as human activity restricts their habitats.
Ephemerals Are very short-lived, growing from seed, blooming and dying within a few weeks.
However, since this may happen several times in the same season, ephemerals can spread quite rapidly. Many desert plants and weeds such as groundsel are ephemerals. The word 'annual' means yearly, and annuals are plants that grow from seed, flower, disperse their seeds and die in a single growing season. Most delphiniums are annuals, so are some herbs, and peas and cereals. Biennials Live for two years.
