Hello, I have a 12 gallon well established (well I think so it's about 1 1/2
years old??) tank. The anubias nana that I have growing on a piece of wood
has just shot out a stem that looks like it has a bud on the end (hasn't
opened yet).

My question is: I didn't think anubias were flowering plants? And why
after over a year is it doing this?

Thanks,
Paige
