cool, that is rare indeed.

is it? wow that's neat then.

Do you have pictures, I'd love to see some :)
Most houses don't have proper lighting for philos nor have enough humidity, unless they live in one of the far south humid states, to thrive enough to flower or even grow without losing leaves on older stems.
I know a lady, in San Diego who has a monstera outside year round in the ground she even gets fruit. My mom had one in Santa Barbara which flowered, up here in the more arid part of the state, I'm lucky if I can keep them from wilting!
