An even better 'at the next party' factoid about avocados is that they're technically monoecious, but practically you need two plants to get good pollination.

Monoecious means they have both male and female flower parts on the same plant ... but interestingly with avocados both bits don't work at the same time.

There's two types of avocado trees, helpfully called type A and type B. Type A is functionally female first, and then (a day or two later) male. Type B is the other way around.

They're one of very few plants to work this way, though I don't imagine it would have confounded early practitioners of agriculture.
