‘Silver Spear’ is a selection from the endangered Chatham Island astelia, endemic to these subantarctic islands near New Zealand. It's an extremely ornamental plant with flax-like leaves sporting an amazing satin-silver-metalic sheen! Offers drama in spades. So very close to being hardy here but not quite. It has taken minus 10 Celsius in our unheated greenhouse but can't freezing combined with rain and wind. Best kept above zero and on the dry side. Worth every effort.
