Orange lily (L. bulbiferum L.). Grows on its own in Central Europe, Corsica, Italy. The stem is erect, 60-80 cm tall, abundantly leafy. Leaves are legless, linear-lanceolate, pointed, tapering to the apex of the stem, up to 10 cm long, 1-1,5 cm wide, with stalked bulbs in the axils of the upper leaves. Inflorescence erect, flowers bright red, odourless. Blooms in July. It does not set seed. Vegetatively propagated by stem bulbs and onion scales. In late summer, the stem bulbs fall to the ground. They are then ploughed up and planted in well-prepared beds at a depth of 3-5 cm at a distance of 5-10 cm. They take root the same autumn or the following spring. Flowering in the second or third year.
