Alpinia hainanensis 'Pink Perfection'
Also known as A. henryi and A. katsumadae. 'Pink Perfection' is one of the most cold hardy Alpinia you can find. It is a beatutiful landscaper that grows well in Zones 8B and above. It is also fairly small (less than 6 ft) so it can be potted and enjoyed indoors. If this Alpinia wasn't perfect enough it is also the only Alpinia with fragrant flowers (light honey scented).
