Annuals

Annual plants complete their life cycle within one year, and then dies.

What is the difference between annual flowers and perennial flowers?

Plants can be classified as either annual, biennial, or perennial. Annual plants complete their lifecycle in one growing season, during which they produce seeds, then die. Familiar annual plants include impatiens, zinnias, and sunflowers. Biennial plants, such as some types of foxglove, live for two growing seasons before setting seed and dying. The term perennial is reserved for plants that live for more than two years. Many plants treated as annuals in Wisconsin are actually perennials which are not cold hardy enough to survive winter here. Examples include Guara, Geranium, Rosemary, and fall mums.

The cold hard truth about annuals. Are they all the same?

Annual plants can be viewed a few ways: true annuals, winter annuals, and half hardy annuals. True annuals, like African Marigolds which can bloom all growing season if deadheaded, stick around the garden all year before they die. For winter annual gardening, choosing the right annuals and the correct varieties is key to creating a colorful planter, window box, or garden bed at your home. Growing them requires taking into account low light levels, cooler soil temperatures, and the occasional extreme weather of systems of Wisconsin's polar vortices. Half hardy annuals describe plants that will tolerate some frost, but not a long freeze, such as China asters or zinnias.

Why grow annuals instead of, say, perennial coneflowers, hostas, salvia, or compass plant?

If you have planted lots of perennial flowers, you are familiar with their longevity. You purchase flower seedlings (or start your own), and plant them in a location best fitted to their needs. You're able to nurture them year after year, fertilize and water them. 

Annual plants afford you the seasonal customization of your beds, pots and hanging baskets; They are floriferous, so they will brighten up mixed borders with non-stop color. Another important aspect about annuals is they often germinate quickly and easily, and they set a lot of seed. Once established, many annuals need minimal upkeep in the form of watering and fertilizing; they are very simple to grow. Annual plants allow you to change your mind next season! Perhaps next year you may try a different color scheme.
