	Here in Zone 3, the falls on BUTTER & SUGAR *stay* yellow for
	the duration of bloom. We have very cool summers. We went around
	on this B & S bloom a couple of years ago on the list, I think. It
	may have been in private mail, can't remember.

	I do have three clumps of B & S, from two different suppliers and
	one is not as yellow as the others. This may be a function of the

	acid soil here, the extreme cold winter and the culture?? Just
	asking...I also have noticed if it doesn't open *real* yellow, it
	will look like creamy white in 2 days. This is on the cultivar that
	is not as yellow or hasn't bloomed as intense yellow. Our individual
	blooms last about 3 days in good color. Blossoms typically last up
	to 4 - 5 days here and that includes bearded irises, especially SDBs.

>Can anyone fill us in on progress toward REAL yellow Siberians?

	I wish I could but maybe the hybridizers will jump in. I am first
	in line to buy them though. :))

	Cheers,
