I don't know what sort of flower this is. The plant resembles a flat cactus and it has produced one flower every year since 1981, when we moved in. Ants are very attracted to it.
Oh but m1469 spiders are supposed to bring you luck! Maybe this spider just wants to bring you luck. Or that one from the tree... that you once almost bumped into. But it doesn't really make me all that happy either if there are spiders in our aparment... specially if they're bigger, it kinda gives me chilles a little. But I'm not angry at them!
Bastards.
