I think I will order Little Trudy from Romence Gardens they have it for $5.49 ea. Last year I odered Major Wheeler honeysuckle from them and it was a very nice large healthy well packed plant, so I may give them a try on the nepeta. They are also located in Michigan.
Placed my order to Romence Gardens for six Little Trudys they come in quart size pots which seems like a pretty good size for the price. Plus Romence Gardens has very good garden watchdog ratings.
