Hi, I finally can grow Ruccola here in Jamaica, thanks to the great assistance of a great member here of this forum! My Ruccola grows quite easily, I think. But recently the leafs turn yellow or purple, and the veins of the leafs are also purple. Is that a sign of the intensity of the Caribbean sun light, or a result of all the rain during the last days, since Jamaica has entered it's tropical rain season. Who knows..?
