Hardly a tougher Impatiens can be had! Cold hardy & long blooming, we've witnessed established plants of this species grow to 4' wide in DRY SHADE. No lie! It's that tough. It also has super-fancy trumpet-like bluish flowers with a curious asymmetry. Fabulous in a hanging basket, especially because the flowers are generally found below the stems & this provides a closer view. Described as being very cold hardy & it's definitely taken brutal frosts here, but we aren't sure exactly how much cold it can survive. Blooms a LONG TIME - late Spring through Fall. Leaves are long & shallowly serrated & show nicely against the plant's licorice red stems. Grows up to 4' wide & around 2' high. From Nepal!
