It is a cutleaf philodendron

It looks like Monstera adansonii, Swisscheese plant.

Hi - Thanks but ,I don't think it is a philo.
It just came up, in an old pot in the garden.
I have philos. So, I do know how they look and grow.
This plant, has one stem and is growing straight up.
Thanks anyway. tina_2

Definitely Monstera, might be M. deliciosa though.
