Anyone have experience with wild bergamot? (North America, East Coast/Mid-Atlantic. USDA region 6)

This is the second year I've had them (Monarda fistulosa). I think they were already a season old by the time I planted them in my flower bed. I had also planted red beebalm (Monarda didyma) and spotted beebalm (Monarda punctata) in the same flower bed. Both of the latter flowered the first year and the red beebalm is already flowering this year. However, the M. fistulosa didn't flower last year and show no signs of flowering this year. They just keep getting taller. I'm certain they're getting enough sun light. Every other flower around them requiring full(er) sun are creating bulbs. I would say this bush is just a dud, but I planted two of these and they're both having the same issue.

Anyone have ideas?
