Discussion

No specimens are known from Rhode Island.

A fast-growing, invasive vine whose aggressiveness may at times approach that of Lonicera japonica, Akebia quinata is occasionally planted as an ornamental; it is of more botanical than horticultural interest. A greenish to whitish flowered variant, known from Asia, is cultivated in North America. The edible, though allegedly insipid, fruits are apparently uncommon in cultivation; cross pollination appears to be necessary for their development (C. S. Sargent 1891).
