    I got 6 'Blue Moon' wisteria seeds from AudreyDee in the NFSR Swap Dec. 2018. I planted them 1-7-19 after I nicked & soaked them overnight. By the 19th (day 12) five sprouted & grew fast. Today, 1-29th, I transplanted the five plants that are already 5" & have several leaves into a little bigger pots. The 6th one just sprouted overnight. Pretty good odds getting 6 of 6 to germinate. I'm so pleased, AudreyDee!
