Chives are a bulb-forming herbaceous perennial plant, growing to 30–50 cm (12–20 in) tall. The bulbs are slender, conical, 2–3 cm (3⁄4–1 1⁄4 in) long and 1 cm (1⁄2 in) broad, and grow in dense clusters from the roots. The scapes (or stems) are hollow and tubular, up to 50 cm (20 in) long and 2–3 mm (1⁄16–1⁄8 in) across, with a soft texture, although, prior to the emergence of a flower, they may appear stiffer than usual. The grass-like leaves, which are shorter than the scapes, are also hollow and tubular, or terete, (round in cross-section) which distinguishes it at a glance from garlic chives (Allium tuberosum). The flowers are pale purple, and star-shaped with six petals, 1–2 cm (1⁄2–3⁄4 in) wide, and produced in a dense inflorescence of 10-30 together; before opening, the inflorescence is surrounded by a papery bract. The seeds are produced in a small, three-valved capsule, maturing in summer. The herb flowers from April to May in the southern parts of its habitat zones and in June in the northern parts.
