Zea — 7 species

Zea is the genus of true maize, encompassing field corn and a vivid array of ornamental cultivars — from the multicolored kernels of Glass Gem to the deep crimson ears of Bloody Butcher. All varieties demand full sun (six or more hours daily) and consistent moisture, especially during pollination; irregular watering causes poor kernel set. Toxicity varies across the genus and related species: Zea mays itself is considered non-toxic to dogs and cats by the ASPCA, but always verify individual cultivars before planting in a pet-accessible area.
