Both of my spotless tiger lily come from Japan as a bulb/plant.
Most of the Japanese website said that yellow tiger lily come from "Tsushima".
The spotless yellow tiger seems found from the seedling plants but not from wild and I don't know the original source of the orange one.
Although I have more than one plant of each flower but I think they are the same clone.
The yellow one I have grown for 3 years and the orange one just bought in May of 2016.
I also keep some rare lilies which is lack of pigmentation that the stem is in pure green and the pollen are in bright orange:
L. auratum var. virginale (which is the spotless auratum)
L. speciosum var. gloriosoides (Taiwan pure white form)
L. speciosum var. clivorum (pure white form)
L. japonicum var. abeanum (pure white form)
The normal form of these lily's pollen and stem should be in dark-brown or reddish brown.
Hong Kong is hot that may not be suitable for some lilies so I keep the lilies could survive in Hong Kong and most of them come from China, Taiwan and Japan.
Some lilies grows well in Hong Kong without any special care just like L. callosum, L. formosanum and L. speciosum var. gloriosoides(Taiwan form).
Some of my collection requires lower temperature in the winter that I would keep them in refrigerator for 1~2 months just like L. auratum var. rubrovittatum, L. speciosum var. gloriosoides(China form) and L. speciosum var. clivorum.
