I do most of my bidding June and July, for seeds. If I plant later than that, they wont bloom the next year, so I go with is offered early. Problem with that is, that seems to be when the seeds are the most expensive. As the year moves on, and the auction is glutted with seeds, they are much cheaper.
Ive rarely buy a new one from the LA, unless its from the hybridyzer. Got tired of plants that were bought and divided and then resold before they could get a good settling in and increase. Every now and then, I see someone post an older one, and I will look for those on the LA. There are a couple sellers that I know send no less than 3 fans, even if they advertise 1, I will buy from them.
I also wont buy anything any more, unless Ive seen it in person or a few pictures from others gardens.
I have bought two plants from Fred, to be delivered in the spring, Im going to order some from the marietta co-op going on.
