Anna, I have bananas planted anywhere from 2-6 feet away from palms. I have them planted closer to taller palms so the bananas can grow underneath the palm canopy and further away from smaller palms. I've never had any problems with roots interfering with each other.

Thanks Momoese, yes it is Bismarckia nobilis - a very fast growing palm.

Frank, I have collected so many palms now that I have lost count. Many of them are in pots. Here's a list of my palms that are planted in the ground (that I can think of right now). Dypsis decaryi, Veitchia arecina, Bismarckia nobilis, Washingtonia robusta, Archontophoenix tuckeri, Dypsis leptocheilos, Cocos nucifera, Wodyetia bifurcata, Roystonia regia, Syagrus sancona, Syagrus romanzoffiana, Sabal mauritiiformis, Sabal bermudana, Phoenix rupicola, Dypsis lutescens, Archontophoenix purpurea, Archontophoenix cunninghamiana, Areca vestiaria (red crownshaft), Caryota maxima, Chamaedorea oblongata, Chamaedorea metallica, Chamaedorea radicalis, Chamaedorea seifrizii, Cryosophila albida, Siphokentia beguinii, Ptychosperma elegans, Kerriodoxa elegans, Carpentaria acuminata and Licuala aurantiaca. I have lots more growing in pots. There are so many more I want to plant but I just don't have the space. I've started planting them in my friends yards now! I'll try and get some pics in the gallery soon.
