not sure nancy?

but could the developing flower head be getting too much direct sun on
it?

i find i need to tie the outer leaves up around the developing heads
like a bonnet so they stay nice and white, don't think the colouration
alters taste or dietry benefits at all though.


snipped
With peace and brightest of blessings,
