If you are doing commercial landscape installation, the need for already grown plants is understood. However, many annual flowers do best when sown directly by seed into the garden.
One such annual flower to grow directly as seed in the garden is the Zinnia.
Zinnias bloom from mid-summer all the way until frost. Though there are about 10 species of Zinnia, Zinnia elegans is most popular and there are many hybrids derived from that species and the crossing of some other zinnia species.
Originating in Mexico, Zinnias thrive in hot climates and need sunny areas to grow.
Depending on the variety, Zinnia plant height range from 2-3 inches to about 3 feet. Besides the size of the plant, Zinnias come in a variety of colors as yellow, orange, white, red, rose, pink, purple, lilac and multi-colored blooms.
Deadheading is the removal of dead flowers. To continue to have an extended blooming season, removing the spent zinnia flowers and the flower's attached single stem will assure a longer blooming period.
The cultural requirements for zinnias are simple. As already stated, Zinnias need full sun and a soil which is humus rich and well-drained.
Besides attracting multitudes of butterflies to the garden, Zinnias also make great cut flowers and are a great plant to introduce to young children gardeners.
