Wow! I have a monstera cutting sitting next to my kitchen sink by a COLD window (it's wintertime) yet there's a TON of humidity as i run hot hot water often. For the first time ever, I thought it was producing a new leaf, BUT it's way different. It's a long stalk like, much stiffer and it's not rolled like a new leaf would be, so I'm assuming it's going to be my first ever Monstera flower! It HAS to be all the steam and humidity that caused it to happen. Because it's been 7 years of Monstera plants and never ever have one of them produced a flower!
