This seedling population has sorta flooded the market over the past 18-24 months. I have seen them offered by both Hawaiian nurseries, and assorted resellers.
I know where they come from (Taiwan), as I found this cross offered in the monthly flask list distributed by one of the major Taiwanese sources.
I have also seen photos of several of the first to bloom. These are all showing flowers with surprisingly deep (dark) colors.
- 'Shu-Ten-Nou' is a well known NF.
- I can find no records of 'Koto'.
- It is generally accepted, that NF 'Yellow' (with strong saturated color) is a hybrid and not a true NF. This also applies to some of the greens by the way.
Being the suspicious old bastard that I am, based on these isolated facts, I strongly suspect that this population with the unknown 'Koto' are not true NFs.
For the record, I have both 'Yellow' and 'Koto' x Shu-Ten-Nou. I have not bloomed the latter yet.
I now invite the orchidboard readers to comment.
