I was expecting them to travel, but I wouldn't be surprised if some of them dont!
Do you have any photos of yours?
I have many off-types going spare, there is more variation than I have space for!
I will be interesting to see whether there is variation in coping with dormancy over winter.
Anyway, here's a couple which were planted outside back in April. Its the one with a red pseudostem (I still consider this one as 'normal', although I dont really know what normal is), and the one with the pink midribs. Other plants in the photo include ensete ventricosum, Musa formosana, Canna etc.
The cool, bright conditions of an English summer make the burmese blue look quite different from the ones grown indoors, but they are growing well; comparable to basjoo and sikkimensis.
