Floppy, Weedy Yarrows

Does anyone know of a great yarrow?  I haven't tried 'Coronation Gold'; that seems to be the most recommended.  I tried some Anthea late in the season, by mail order, and the plants were doomed when they arrived.  They had a serious stem rot going on.

I've tried Summer Pastels and now Papricka (I do like the color), but they flop and the inevitably look weedy.  Also, like hair color, they fade.

I'm not sure that these are any better, but, Pretty Woman is an interesting red.  Somewhat of a cranberry.  And, Pink Island Form looks good in drifts.  Thoughts?
