Typical presentation of MTB Agate Pass

I found this picture I took in 2003 of Agate Pass in VA, in the garden I then bought it from. I see why when mine first bloomed so yellow here, I wondered who it was, and wrote NOT on the sign. Putting this picture side-by-side with the picture from my garden… same form… same pattern markings on falls… Well, look at that - that first one posted IS Agate Pass.

Mine matches the description ‘S. yellow-beige; F. beige with pale blue wash through center; orange beard.’, but the yellow of the yellow-beige is more expressed here. I had it verified by someone at MIS, who noted the typical presentation is this more beige.

This is a nice example of an environmental color difference. Now I wonder if that 2nd yellow above (Ozark J-Not) - which grows about 20 miles from me - is also atypically colored. I had sent the question if its ID to Terry Aitken as you suggested, irisMA - he could not ID it.
