Too funny, after reading this thread, I took a look around and I have two of these that appear to have sheaths forming. They are from Little Frog, but for the life of me I don't recall buying them. The cross is OIP0217, Fumi's Delight "Rainbow" x delenatii "Purple Delight". I also have a flask of these from Sam, but with different parents, OIS0232, delenatii var. vini "Crystal Purple" x Fumi's Delight "Zack". The seedlings from the flask are running about 2 years behind the ones from Little Frog. The odd thing is that the ones from the flask seem to generate a lot of stolons that like to grow vertically. I think keeping them in the pot will be a challenge. It may be basket time for these guys. Mike
