WOW..and such a good start you had with it...maybe it needs to be root bound.. it has been quite the mystery for me also...I tried a few new vines this year.. the wonga wonga vine has yet to bloom also..... and I've found a faster.. more robust grower this year.. my argentine pink trumpet vine... has proven to be twice the grower and with abundant flowers already from a 10" bare rooted plant in the spring.. lots of sprouts over 20' long.. and a mass of growth...voted the best grower 2012
