That's really interesting about the bitterness of the yellow oriental bulb, Della.
Sorry you can't get a hold of Netty and it's a pity I can't send you some as I for sure would have many to share
Hopefully it will become available in your part of the world in time. In fact a bit strange that it isn't already as I thought it was one of the more common and popular cultivars. One thing I however didn't really like with Netty was that it seemed to open all flowers almost at once, so had a very short flowering time.
