The classic snowdrop with full green inners is called 'Merlin'. This dates back to the 1890s when this was a noteworthy feature. As more of these emerged they were often given the name 'Xyz Merlin'. For example, I grew 'Tubby Merlin' for a while which was a fine snowdrop, although I seem to have lost it. The name of Avon Bulbs' recent snowdrop 'The Wizard', an inverse poc. Trym derivative, alludes to 'Merlin'. But these days the number of snowdrops with good green inners is too numerous for me to count.
