Lilium speciosum

Lilium speciosum is an East Asian species of plants in the lily family. It is native to southern Japan and southern China, where it can be found on elevations of 600–900 metres (2,000–3,000 ft).[1][2][3] It is sometimes called the Japanese lily though there are other species with this common name.

Lilium speciosum has flowers up to 1.2 metres (3 ft 11 in) by 0.3 metres (1 ft 0 in) in diameter, blooming from August to September in north temperate regions.[4] The flowers are white to pink in colour, and strongly scented. It is later flowering than most other species. Many garden forms are in cultivation, and the species has been widely used for breeding of garden forms.

Lilium speciosum contains phenolic glycosides, such as 6′-O-feruloylsucrose and (25R,26R)-26-methoxyspirost-5-en-3β-ol 3-O-α-l-rhamnopyranosyl-(1→2)-β-d-glucopyranoside, and steroidal saponins.[5]



Cats are extremely sensitive to lilly toxicity and ingenstion is often fatal;[7][8][9] households and gardens which are visited by cats are strongly advised against keeping this plant or placing dried flowers where a cat may brush against them and become dusted with pollen which they then consume while cleaning.[10] Suspected cases require urgent veterinary attention.[11] Rapid treatment with activated charcoal and/or induced vomiting can reduce the amount of toxin absorbed (this is time-sensitive so in some cases vets may advise doing it at home), and large amounts of fluid by IV can reduce damage to kidneys to increase the chances of survival.[11]
