I was going to reference this 6-year-old thread in a new one, then realized I could just bump it up. Glad I found it, because Tink3472's (Michele) explanation is wonderful and I thought it may help others who are wondering about TC.
The subject of TC was brought up in this thread and was the reason for my search to know more about it.
The thread "Brecks daylilies" in
Daylilies forum
I was surprised to find this 1988 Chicago Tribune article featuring Roy Klehm:
http://articles.chicagotribune....
In it, hybridizer Roy Klehm says he used tissue culture to increase stock. I was wondering if this was an accepted practice back then and if is still done today by any hybridizers or if it is considered taboo now.
I have been avoiding buying daylilies from the big box stores because I knew they were TC. But now after reading this article, I wonder how many daylilies I might have that are TC because if several hybridizers did this 30 years ago, there's no telling what's being sold and traded out there. It could explain a lot when we compare our cultivars and one person gets great performance while another person doesn't.
Hoping someone can elaborate on what hybridizers think of tissue cultured daylilies. If it is practiced today, I also was wondering how many years they evaluate a TC daylily before selling the stock.
