Perennials:
A perennial is a plant in which grows back year after year and usually dies down to dormant roots each winter. Some perennials live only four to five summers while others can be enjoyed for decades, however; if maintained they can and should be divided every three years, thereby; increasing the chances of always having the plant.

Annuals:
An annual is a plant that completes its life cycle, from seed to bloom and back to seed again, all in a single growing season. A practical definition of annuals is that they are plants that have to be replaced every year in the garden. They are reliable in the flower garden in the sense they are continuously blooming from Spring through Fall, but again only reliable for one season unlike perennials.

Tomorrow I shall write the benefits of having perennials as well as annuals, however; my preference is perennials but I do like to use annuals as fillers.

That is it for today....
