Hippeastrum petiolatum grows to a height of 30–40 cm. Leaves are lanceolate, and dark green, forming a basal rosette around 60 cm in diameter. They grow to a length of 20–50 cm. There are up to three scapes per bulb. The paraperigonium consists of minute scales at the throat of the tepal tube, whose segments are unequal and ruffled and 1–2 cm broad at the middle and 15 cm long. Perigone 6–7 cm. The showy flowers are 10 cm in diameter, scarlet-red with purple veins, greenish-yellow in the throat and usually 3–4 in number but may be 5 rarely. Stigma trifid. Bulbs large (10 to 15 cm in diameter).[3][4]
Full sun to part shade, moist but well drained soil, or pots. Leaves may persist all year under optimum conditions. Reproduction is solely by lateral bulbils, and bears no fruit.[4]
