I rarely, if ever, post on the Ping forum, but here I am anyhoo!
A while back I purchased a large Pinguicula x 'Gina' (syn. 'Hans'). Eventually this plant made one of those mutant "pitcher" leaves, which Kit Halsted reported a while back.
I removed that leaf and am currently rooting it successfully with my usual Ping propagation tek (chuck 'em into the highland Neps' house onto LFS), and will report back on anything interesting that may happen (though I VERY highly doubt it) regarding the leaves it makes.
I'll take a pic of it later.
