hi everyone,
I'm italian but next july I'll go to New York, I would like to buy something like plumeria, cordyline, but mostly bananas

How can I do this ?

I'm searching these varieties:
- siam ruby
- praying hands
- ae ae
- sweethearth
- veinte cohol

e lady fingers
- pisang susu
- pisang klotek
- pisang mas

I don't know if there are better varieties, but I have to buy from which nursery according to you ?
In New York directly or for example from Florida to me in New York ?
And then for the trip to coming back to Italy in order to avoid whatever problem with custom, what I would do ?
Obviously no earth but only bulb, but there are limits of plants? in the suitecase ?

thanks
