Wasn't aware of the mulberry plants being single sexed. Of course, if only male (or only female) plants were introduced and the plant is incapable of producing hermaphrodites, then no seed can be produced and no seed-based invasiveness. This has no bearing on seed-grown versus cutting-grown. If a plant that has both sexes on the same individual, then a cutting from it can grow to produce seed. The invasiveness I was speaking of was the underground spreading by root over a large area relatively quickly, the concern of the Greenwell gardener. Let go, this sort of spreading can take over large areas, such as the bamboo forest along the Hana highway. But other than caution of the gardener, I don't have any data on exactly how fast the wauke will spread.
