Zinnia FAQs
When do zinnias bloom?
Zinnias bloom from early summer until the first frost, often flowering just six to eight weeks after sowing and continuing for months if you keep cutting them.
Are zinnias annuals or perennials?
The most popular garden zinnias are annuals, completing their life cycle in one season, though they often self-seed and reappear the following year.
Do zinnias reseed themselves?
Yes. If you leave some flowers to set seed, zinnias will often drop seed and come back on their own the next season, especially in mild climates.
