I just took this photo of the the amazing Tibouchina urvilleana ‘Variegata‘ sporting its winter colors.  As temperatures in our cold frame hover around the mid-30’s – 40s, the foliage takes on this amazing purple overlay. When temps drop much below freezing, tibouchina becomes deciduous, but if you have a cool greenhouse or sun room, what a gem.   Who needs those incredible purple flowers when you have foliage like this?
