This shrub is from the mountains of Mexico and has distinct leaves and stipules. They are very ornamental which is fortunate in the UK as in many years it gets frosted before it flowers. It does sometimes flower well before the frosts come and they are a strong yellow which can mean siting it is a problem especially if you have it combined with the wrong colours because the leaves go so well with so many planting combinations. It's annual growths are up to about 2 meters. I have grown it now for about 20 years and after about it's 4th year decided it had got too big where it was and tried moving it which was totally successful. In effect in London I treat it as a herbaceous perennial cutting it down to the ground each season.
