Hi, woori Shark-fin melon is one of the many common names for C. ficifolia... There are different skin-colouring: some varieties are white, some pale green or dark green and some are striped... There is also a variety with white seeds although much less common than the black-seeded one. The plants are perennial in Queensland but I don't know if this is also true for Victoria. Rose-Marie |
