The tomato (Solanum lycopersicum) is a plant in the Solanaceae or nightshade family, as are its close cousins tobacco, chili peppers, potato, and eggplant. The tomato is native to Central, South, and southern North America from Mexico to Peru. It is a perennial, often grown outdoors in temperate climates as an annual, typically reaching to 1–3 m (3 to 10 ft) in height, with a weak, woody stem that often vines over other plants. The leaves are 10–25 cm long, pinnate, with 5–9 leaflets, each leaflet up to 8 cm long, with a serrated margin; both the stem and leaves are densely glandular-hairy. The flowers are 1–2 cm across, yellow, with five pointed lobes on the corolla; they are borne in a cyme of 3–12 together. The word tomato derives from a word in the Nahuatl language, tomatl. The specific name, lycopersicum, means "wolf-peach" (compare the related species S. lycocarpum, whose scientific name means "wolf-fruit", common name "wolf-apple").
