Thanks all for your comments I am glad that I am still managing to show somethings to interest you after all these years

Mark - The Fritillaria imperialis are my own seedlings and they seem to flower better for me.
David - There are an amazing range of Frits of all colours and many have the checkered effect.
Ed - It is Erythronium 'Susannah' the best yellow hybrid that I know of between tuolumnense and oregonum.
