The zinnias are starting to produce more flowers, and today a new color, yellow. They come in hues of orange, pink, purple, red, white and yellow. They are fast growers and bloom heavily, but are annuals, so the original plant will not come back the following year.

There are the single, semi-double and double zinnia, which differ in the number of rows and petals the flower produces. These flowers also come in the beehive, button and cactus forms of flowers, as well as in different heights.

They love soaking up full sun, preferred six to eight hours, which promotes more blooms. Also, deadheading, getting rid of the dead flowers, encourages more growth.
