Hello, so this is my musa 2 years old. It has suffered, quite badly.

I moved it from an exposed place to in me back near greenhouse, so I can care for it more. It's now in a spot with sun all year.

So before planting I double dug, added well rotted manure and bonemeal blood and rooting hormone to help it on way. I have also added a small top dress of slow release food with micronutrients.

So what can I plant with it?

I have 3 hostas that still in pot. I have some eucomis and hymenocallis festillis
I am assuming I need plants that won't pinch too much nutrients.
I have read cannas as good as they're similar looking,
I'd love to put a disksonia Antarctica with it. But I think it's wrong plants.
I have 20 echium (towers pink white blue) that I am yet to over winter what about those?
I'd like something I can use to help protect plant in cold. (oh am in Wiltshire uk)

Any help would be great!
Thank you
