It is a vigorous perennial vine which grows well in mild climates with no danger of frosts. You can plant them in early spring - a picked fruit will grow a sprout (just as potatoes do) then put it directly into the soil but leave the sprouting end just uncovered. The vines will then fruit in autumn and winter. The green fruits are pear shaped and sized and have squash type flesh (marrow). Grow on a trellis or fence with plenty of room around them.
Both male and female flowers occur on the same vine. The flowers are pollinated by wasps and bees and the fruits mature about 35 days later.
