Re: Anthocyanin-sidetracked

I didn't realise or had forgotten that you had first generation plicatas. I'll need to find the pics to have a look see. How to interpret this requirs a bit more exploration as sualeolens doesn't show plicat pattern by itself.
A number of glaciatas actually show anthocyanin in various ways. There is a pattern with anthocynain in lower epidermis but absent in upper epidermis , called Celstar. The aphylla cultivar White Mutant (has been demonstrated to be a glaciata) shows a lot of anthocyanin in bud and can show some when opened. Fred Kerr has also noted glaciata cultivars with anthcayanin. I would expect White Mutant to have AVI and thus not fully repress the anthocyanin which is extra strong with AVI present. I wouldn't be suprised if that is also the situation with Fred Kerr's seedlings.

OK. Yours are second generation, my plicatas were first generation plicatas. Swertii X I suaveolens, about 1/2 plicatas. Hard to say since I didn't have many seedlings and wasn't worth repeating. Even a plant not showing plicata pattern may still carry it into the second generation, especially since it is not apparent in I. suaveolens and those that weren't highly resembled I. suaveolens in color distribution.
