Zinnia is a common Mexican wildflower. The early Spanish colonists in Mexico found the flowers ugly and called them mal de ojos (evil eyes). The genus was named after German botanist who first named it, Johann Gottfried Zinn of Gottingen. Of the 200 or more species (source) in the zinnia genus, Zinnia elegans is the most well known.
Low, erect annual herb, growing to a height of 1 to 3 feet. Leaves are opposite, ovate or nearly elliptic, with the base clasping the stem. Flower head is terminal, single- or double-flowerd. The flowering stalk is 2-5 cm long. Ray flowers are reflexed, of various colors, disk flowers usually yellow or orange.
Native to Mexico.
Widely distributed in the Philippines.
Thrives best in deep loamy soil.
Propagated by seeds.
• Antifungal. Phytochemical and antifungal screening of the whole plant of Z elegans yielded 7.6% saponins and showed pronounced antifungal activity against Fusarium moniliforme.
• Allergenicity / Allergic Rhinitis. Zinnia elegans pollen from heavily polluted areas in central Tehran has been shown to release compounds that are significantly more potent in eliciting skin wheal reactions and increasing total blood IgE (immunoglobulin E) and eosinophilia in sensitized animals, than pollen compounds from non-polluted areas.
