Lilium sulphureum (synonym: Lilium myriophyllum ) is a species from the genus of lilies ( Lilium ) in the trumpet lily section .
description
Lilium sulphureum reaches a height of 100 to 180 cm. The onions are large, round and reach a diameter of about 10 cm, they are covered with red to purple scales.
The stem is hard and straight. The leaves are narrow and linear to lanceolate, between 7 and 13 cm long and between 0.8 and 1.6 cm wide. They are distributed around the stem, in the leaf axils, and form axillary bulbs similar to Lilium sargentiae , through which Lilium sulphureum reproduces vegetatively. In contrast to those of Lilium sargentiae , these are brownish-red.
The plant blooms from July to September with inflorescences of 1 to 15 horizontal, trumpet-shaped flowers that are strongly scented. The hermaphrodite flowers are threefold. The six identical petals are bent back and 17 to 19 cm long. The basic color of the flowers is ivory white, which changes to golden yellow towards the base, the outside of the flower is tinged with pink. Each flower contains three carpels and six stamens. The anthers and pollen are brown and the filaments are yellowish green. The seeds ripen in 4 cm to 5 cm large purple, cylindrical seed capsules and germinate immediately - epigeously .
The number of chromosomes is 2n = 24.
