Hibiscus

About a month ago I bought two Hibiscus plants - one blue and one pink - the blue one has been covered in flowers that I think have now finished and I was convinced the pink one was going to do nothing at all, as it showed no sign of wanting to produce any blooms..........until this morning when it now suddenly has three beautiful flowers on it......maybe it likes the rain, even though I've been watering it.......whatever the reason, I'm not complaining :-)
