Flowers are visited by a diversity of pollinating insects, mostly bees and flies.

Plants were found to be cryptically dioecious (i.e., male and female plants have

morphologically similar flowers). Both males and females produce pollen, although the

pollen on the female flowers was not functional in stimulating fruit production in other

plants and male plants produce no fruit (Ambrose & Kevan, 1990; Kevan et al., 1990).

Being functionally dioecious, isolated individuals are not able to produce fruit. The fruit

is a hip, typical of roses, with a fleshing receptacle enclosing hairy achenes. Clonal

reproduction is occasionally seen around older plants, in the form of new plantlets

developing where the tips of branches touch the groun

Functionally dioecious and susceptilble to mildew, eh?

Hmmm… Barring anyone convincing me that its descendants are really great plants, I may pass on using this one as a parent after all…

but dang, it sure does have some pretty babies out there…
