My guest is that it's just a dandelion. Theres no question as to how that could get into a patio container. Michael
when you look closely, it looks like it has white speckles, like some calla lilies do. did you plant a calla last year? the leaves look too thick and not the right margins for a dandelion. i don't know though, just guessing.
doesnt look like a dandelion to me, leaves look similar to Eucomis but its too early for them, if in doubt, wait and see.
