If a bush of setigera produces hips, it is a female plant. Blooming setigera plants not producing hips are male. Most dioecious species have separate pollen and seed-producing flowers but setigera has an additional deception, called “cryptic”. The male and female flowers look exactly the same, both having anthers and pistils but the pollen of female flowers is sterile and the pistils on male flowers will not function.
