John,
Many thanks for the speedy reply. I have passed on a link to these postings to my friend and, hopefully, it will lead him to the seed he wants.
On another topic: G. "DA" is performing in a manner beyond all belief and hope. I lifted the bulb at the end of last season and had three joining bulbils. One I sent for twin scaling, put one back in the original posiiton and the third in a new position. That in the new position, the smallest of the offsets, has a flower above ground. The other has SIX shoots though no flowers apparent yet. Imagine that! Isn't it an amazing rate of increase.
