If Vireya rhododendrons have started blooming, it’s winter in the subtropics. Vireyas are a subgenus of rhododendron, they are tropical shrubs originating from SE Asia to Australia. Many hybrids have been produced, some are very fragrant, and most are ideal for container growing on a balcony, on (or under) a tree, or in a shadehouse. In my experience, treating Vireyas as you would an epiphytic orchid really helps. Vireyas make good cut flowers and buttonholes (remember them?). If you start a collection, you can have them blooming over many months.
