Plants just make me happy and if they make the air better at the same time too, it's a plus! Avocado is one of my favourites, it's been growing really nicely this spring/summer.

I've had one going on the windowsill for over a decade, no avocados yet. ;)

I’ve heard it’s somewhat impossible to get it to bear fruit.

I think in a non tropical climate it is unlikely. In good conditions they take 7 years to bear fruit and starting one from seed is unlikely to produce a good fruit. Pretty much all avocados that we eat are Hass avocados and they are all clones of the same tree.

I can buy the fruit from the store, I just like the way the tree looks, though mine is still a baby. I gave one to my mom over a year ago and it's taller than me!
