I haven't seen any commercial suppliers.
I've gots lots of seed from Monarda punctata, collected in the garden 08. Send me an email if you're interested.
Do you have pink? I adore all colors.
The seed for this plant was originally purchased from Prarie Moon nursery. It looks pretty much like the typical Monarda punctata, spotted yellowish flower with pinkish bracts. It is not very pink. This pic shows some of the flowers when they first started blooming.
