Without looking it up, I think subtropical would be more correct for Gunnera. They're more from higher altitude regions rather than the lowland tropics. The miniature Gunnera magellanica is winter-hardy here in Zone 6B (Detroit area) without protection. The larger species are winter-hardy in this area with protection (though not in my space-prohibitive yard!). With the miniature species, at least, protecting it from winter desiccation is a major factor in survival. I've noticed with many species winter-hardiness is a matter of soil moisture -- too much or too little, depending on the species -- rather than temperature. Dean Sliger +More Warren, MI, USA Zone 6B
