Narrative
Hippeastrum x hybridum ‘Antoinette’ is a tall bulbous herbaceous perennial. Bulbs are 4.0-5.0 cm diam at first flowering, maturing to 7.0 - 8.0 cm, producing 2-3 offset bulbs annually. Leaves are strap-shaped, green, two to four per bulb, 60-70 cm long, 5-5.5 cm wide. Scapes are 50-60 cm tall, usually 3 per bulb, each bearing 4-5 flowers per scape with pedicels 2-3 cm long. The semi-trumpet perianth is 14.5-16 cm long, laterally ca. 13 cm and dorsoventrally 14 cm wide. The six tepals are of medium texture. The outer tepals are 10-12 cm long, and 3.5-4 cm wide at their broadest; the inner tepals are 9.5-11 cm long, the inner laterals 4.5-5.0 cm wide; the ventral inner ca. 3.5 cm wide. The tepals are striated marginally with lilac-pink on their adaxial surface, with RHSCC red-purple 66C the closest match, and with broad central white keels. A white underlay can be seen on the tepals. The throat is emerald green, becoming yellowish-green at the margin. The tepals are similarly colored on their abaxial surfaces, and the tube is infused green. The tepals are coarsely undulate along their margins. Stamens are 12 to 13 cm long, white distally, then green in the proximal ½ of their length; pollen is yellow. The style is 13-14 cm long and colored similarly to the staminal filaments; the white trifid stigma is ca. 7.0 mm wide. This a complex, fourth generation hybrid that began with a cross of two primary hybrids: (H. ambiguum x H. papilio) x (H. papilio x H. lapacensis), with successive crosses with H. brasilianum.
