I would guess it is because I have it in the greenhouse and the climate does not change. Mine blooms almost all winter , rests a month or so and then starts again and keeps going. I would guess there are no more than two months out of the year the plant does not have a bloom on it. Yes, mine is a bush in a big old square pot.
Nothing special or fancy. i do not even know the name of it because the dog ate the tag. I do remember it was patented so I never tried to propagate it.
