Hippeastrum x johnsonii (Hardy Amaryllis) is a clump-forming, bulbous perennial boasting ravishing clusters of 4-6 slightly fragrant, trumpet-shaped flowers, 5 in. across (12 cm), in late spring. The blossoms feature 6 gracefully recurved scarlet tepals, each with a central white stripe down its center. The flowers are borne atop stout, upright, hollow stems. One bulb can produce up to 4 stems. The foliage of semi-evergreen, strap-shaped, deep green leaves, up to 2 ft. long (60 cm), can take on coppery tones when grown in full sun. Vigorous, the bulbs increase quickly, forming a charming colony, if left undisturbed for a while. Hardy Amaryllis is the hardiest of the Amaryllis and can withstand winter temperatures to 0°F (-18°C). In cool climates, this bulb is winter deciduous, but in warmer areas it is nearly evergreen. Hippeastrum x johnsoniii a hybrid between H. reginae and H. vittatum. It is believed to be one of the first hybrid amaryllis, produced in 1799 by English watchmaker Arthur Johnson.
