Thanks to those who advised me on the lily seed. Now I am wondering if I can pick your brains, on how to germinate Leontocher ovallei seed? If its of any interest to anyone I got them from Chiltern Seeds (England) along with some other bulb seed and they had a Californian native Delphinium too. I to have been told that vinegar is good but I have not actually tried it.Although I have used Sulphate of Iron in the open garden and found that it worked but then that was lawn. Malcolm Redwood.
