Japan, Korea, eastern China and Manchuria are the home of this lily. Like potatoes, the bulb contains starch, and it is cultivated, cooked and eaten in both Japan and China; in fact, it resembles the taste of mashed potatoes. The Japanese name for this triploid lily (three sets of chromosomes) is Oni-Yuri.
The bulb is white, the scales are thick, fleshy and broad. The stiffrises 3 feet 3 inches-4 feet high, and bears arranged in a regular pattern. The round, black-brown axil bulbils develop from June onwards and when fully ripe drop on to the ground during autumn. The
racemosely arranged blooms open during late August or early September to expose strongly recurved petals of orange-vermilion red bearing numerous chocolate-brown spots; red-brown pollen. L. tigrinum is self-
sterile, butformation (most are not viable and resulting short-lived) is possible if it is crossed with carotenoid-containing lilies (e.g. L. maculatuni, L. bulbiferutn, L. x umbelhtiini, L. amabile, L. davidii, L. leichtlinii var. maximowiczii). L. tigrinum var. splendens has the
largest distribution of all the triploids. The variety fortunei has salmon-orange blooms with densely woollyand flower buds, while var. fiore-pleno is less attractive, and unimportant, (NALS-LYB 1954)
L. tigrinum var. diploid is self-fertile, has the normal number of chromosomes (an = 24) and is also capable of being crossed with the car0-tenoid-containing lilies listed above. Its distribution area is small, and it is only found in the island of Tsushima and on the opposite Kyushu coast. Jan de Graaff has used this small-flowering plant, which is weaker than the triploid, in many of his crosses.
L. tigrinum var. flaviflonim Makino 1933. A yellow-flowcred diploid of weak growth, with 2n = 24 chromosomes, which plays a large part in the breeding of yellow-flowering Tiger hybrids.
Crosses with L. tigrinum have been made with the following lilies: L. amabile (Cardinal); L. bulbiferum var. croceum (L. x uianglesii); L. leicht-linii var. maxiniowiczii (Tigriinax); L. x niaculatuni (Margaret Johnson, L. x umbtig).
L. tsingtauense Gilg 1904
From the Chinese province of Shantung and the Korean Diamond Mountains. Although already known since 1863 and often confused with L. medeoloides in the past, it was not given its present name until 1904, when Gilg collected it at Tsingtau.
The I-inch white bulbs are oval. Some scattered and lightly marbled, but most of them in whorls, clothe the 16-36 inch high stem. This carries one to six erect, star-shaped, reddish-spotted with irregularly arranged, shiny orange-red segments; light, unpleasant smell. Orange pollen, slightly winged, short, stubby capsules, large wingless , slow germination, flowers at end of June. This interesting lily, with varying characteristics, is easily raised from seed, but needs light shade (from ground cover) and conditions damper than normal.
Crosses with Marhan hybrids are said to be possible.
L. tsingtauense var.flavuni. A yellow-flowered variety.
