Zinnia21 species

Part of the Daisy & aster family family (Asteraceae)

Zinnia is a genus of cheerful warm-season annuals — including common Zinnia, Mexican zinnia, Peruvian zinnia, and the compact Profusion orange zinnia — grown for their vibrant, long-lasting blooms in virtually every colour. They demand full sun (at least six hours daily) and well-drained soil, and are notably heat- and drought-tolerant once established. Deadheading spent flowers prolongs bloom from early summer through first frost. All Zinnia species are non-toxic to cats and dogs, confirmed by ASPCA, making them an excellent choice for pet-friendly gardens.

Zinnia — frequently asked questions

Are Zinnia plants toxic to cats and dogs?

Most Zinnia are pet-safe. Of the 21 Zinnia species we cover, 21 are non-toxic on the ASPCA list and 0 carry a toxic or mildly-toxic rating. Even so, confirm the individual species before trusting it around pets.

How much light do Zinnia plants need?

Most Zinnia do best in direct sun. If yours stretches toward the window or loses its variegation it wants more light; scorched or bleached leaves mean it is getting too much direct sun.

Are Zinnia easy to care for?

Some Zinnia suit more experienced growers — several want strong light, sharp drainage or a specific seasonal rhythm. Check the individual species page for the exact regime.
