I should have added. I did make a comment that the photo closeup showing the flowers is 'Sulphureum', not 'Neosulphureum'. Among the differences, 'Sulphureum' has bright yellow cup, with spurs almost as long as the sepals, whereas in 'Neosulphureum' has light yellow cup and short spurs half as long as sepals. There are other differences, but those two features make it easy to separate the two. I grow both, obtained from reliable sources.
