2014 December 12, Ken Thompson, “Do plants have a gender? Most plants are hermaphrodite, but not all – and an interesting situation arises when only one sex is imported into the UK [print version: Alien plant species in search of a mate: Although most plants are hermaphrodite, some come in two distinct genders. So how does a single-sex community develop?, p. W28]”, in The Daily Telegraph (Weekend):
-
Most plants are hermaphrodite, even if some of them (hazel, for example) keep their male and female flowers apart. But some plants are dioecious, i.e. they have separate sexes. Some of our most familiar wild plants, such as nettle and red campion, are dioecious. If your holly never has any berries, that's probably because it's a male.

- (zoology, rare) Having two distinct sexes.

Dioecious (Greek: "two households") is the property of a group of bilogical organisms that have males and females, but not members that have organs of both sexes at the same time. I.e., those whose individual members can usually produce only one type of gamete; each individual organism is thus distinctly female or male. The majority of animal species (for example, all mammals and most reptiles) are dioecious. The term is rarely used for animals, probably because it is the common state for animals. The term is most often used in plants. The majority of plant species is monoecious, hence has either bisexual flowers or possesses both male and female flowers on the same plant, but still a large number of plant species is dioecious. See plant sexuality, for a full description of more complicated situations in plants.
