Greg if you have them outside you should get blooms at least by the 3rd yr as long as you do not cut the tops off. I found when I cut the new growth this year I do not get the blooms on that plant the next year.
The other issue may be you are getting too much moisture in the winter. They need to be dry and cold. Maybe this winter cover them if you get rain. Put a blanket or garbage bag over them so they do not get moisture for 3 months during the winter.
