description Zinnia Overview

Zinnia is a genus of flowering plants in the daisy family, native mainly to the Americas, with Mexico being an important center of diversity. Garden zinnias are usually grown as annuals for their brightly colored flower heads, long summer bloom period, and usefulness as cut flowers. They are popular with gardeners because they tolerate heat and can attract pollinating insects. Zinnias were also grown as part of plant experiments aboard the International Space Station.

help Zinnia FAQ

Is zinnia an annual or a perennial flower?

The common garden zinnia, Zinnia elegans, is usually grown as an annual. It is native to Mexico and normally dies after frost rather than returning as a hardy garden perennial.

Can zinnias be grown directly from seed?

Yes. Gardeners commonly sow zinnia seed directly into warm, well-drained soil after the danger of frost has passed, because the plants dislike cold roots and disturbed transplanting.

Why are zinnias popular as cut flowers?

Zinnia elegans produces colorful flower heads on strong stems and can bloom through much of the summer. Removing spent flowers, known as deadheading, can encourage more blooms for bouquets.

Do zinnias attract pollinators?

Single and semi-double zinnia flowers can provide accessible nectar and pollen for bees, butterflies, and other insects. Double cultivars often have more petals packed into the flower head, which can make the center less accessible.
