I've had ALWAYS AFTERNOON for a number of years. It was one of the first plants that I ever acquired. It's grown from a small single fan into a massive clump. It performs reliably here with little intervention from me, however, a good feeding in the spring and fall does seem to increase bud count. I have found it to be reliably fertile, easily so, and will often set pods with (for a tet) a large number of seeds. I have actually crossed a few newer plants (like DRAGONFLY DAWN) back into ALWAYS AFTERNOON due to how well AA performs for me.
I've never made note about it's rust resistance so I cannot speak to that. It blooms mid to mid late season for me and does not rebloom.
