A species of what? The quickest climbers a the zoo are the monkeys but I guess you mean a plant. If this is one you have seen could you describe it, supposing you didn't take a photo? height, flower shape and colour, leaf shape etc.

Hi and welcome to g o y, I don't know of 1 that climbs, there are upright perennials, or spreading perennials.
Hi Sue, the question is about Mimulus, and you're almost right, M cardinalis is commonly called "scarlet monkey flower" and M luteus monkey musk, or yellow monkey flower and M ringens, Allegheny monkey flower, so you got the monkey bit, lol, Derek.

I think that Ruthhomes is trying to have a laugh with us Steragram. Haha

Ah, a quiz question - well I tried! Never been to Bristol zoo.
