Hi Mark, just a couple of comments on this post. The images on the earlier part of the chain don't show up. Maybe a broken link? I came to this page trying to search for Boechera Koehleri which was the nominal name for a wonderful little plant that I got via the 2013 NARGS seed distribution. Like you my plant doesn't look anything link the nominal namesake. Instead it's a pretty little yellow flowered plant that is very hardy and flowers abundantly . I'm still trying to puzzle out what it actually is since I don't see any listing for a yellow rock cress.
Hello John, welcome to NARGS Forum. Regarding the missing images, when the previous NARGS Forum was migrated over to the current web-format NARGS Forum, images in the very first post of numerous topics were lost in the translation. Regrettably it appears to be an unfixable item. Your yellow "cress" looks like it might be an Erysimum.

Nice to here from a fellow seed grower, John!
I'm an addict, and proud of it. I'd like to welcome you to the forum, also.
The occasional misidentification in seed exchanges is unfortunate, but I easily overlook it and revel in the huge assortment of choices not to be found anywhere else in commerce. Sometimes you get something even better!
