I think it would be well worth it for your B'fly/Hummingbird garden! The hummingbirds especially love Bottlebrush blooms! I have the Weeping Bottlebrush (Callistemon viminalis) in my backyard and the hummingbirds are really attracted to those bright red flowers. I read that Callistemon subulatus is a shrub that's hardy to 10ºF so I'd think you could easily grow it as a container plant and move it indoors when temp's drop. Another dwarf variety that should be good for containers is Dwarf Bottlebrush (Callistemon citrinus 'Little John')
