Best Chance of Success with Banana Seeds?

I bought 3 packets of 10 seeds each of Musa Mannii, Musa Coccinea, and Ensete Superbum, from Jungle Seeds. I did initially query the viability of the Musa Coccinea seeds as they floated when I put them in water to soak. However, it was the Ensete that didn't germinate at all while I got one seed germinating each from Musa Mannii and Coccinea. I did try just keeping the heated propagator on all the time for weeks and then read about an "on and off" system of heating when trying to germinate Musa. I tried that and after a few weeks got a result....but that could just be coincidence and I can't prove it was that method that caused the seeds to germinate. So, for me, it was a 10% success at getting the seeds to germinate with two varieties and a total failure with the third variety. I know there's the argument about "well, it's cheaper to buy a plant" rather than struggle for weeks/months trying to germinate seeds, but for me it's the challenge of trying to get some sort of success that makes me choose to sow and hope!! I will try again in the coming season and go for other varieties but I will include Ensete Superbum as it's a challenge and any sort of success is a lucky bonus.

 

I have trouble telling one Banana from another, Sal, as they all look yellow/green and bent to me!!! It's a good idea and suggestion thought and [sorry for the pun] food for thought.
