A brief note on this genus, due to the insane importation of trees and shrubs and much else from around the world, specifically from China where species within common genera found in Europe and North America are resistant to these viral and insect parasites, etc, enjoy your A. parviflora which we have here too for as lone as you may because a dire situation is not raging across Europe, imported from plants grown in the East and inexorably making it way north in my direction. A very dear friend who has a wonderful collection of species in this genus, perhaps the best in Europe and located in northern England told me when he came here recently on his annual Scottish salmon fishing pilgrimage that he thinks it already in his arboreta and I should keep an eye out for it. Fortunately we are sufficiently far enough north and away from potential infectors combined with everything either grown from seed or quarantined elsewhere we MIGHT get lucky. I think from memory this problem is one of the Phytophora species and related to the one which arrived from a similar source into North America and is wiping out your western Oakwood's, that one is now also in Europe and affecting Rhododendron, Fagus, Acer and much more in south western England, even Scotland's iconic Heather - Calluna vulgaris, as well as along the Atlantic coastline right up into soem of the famous gardens in western Scotland. The next thing our government has warned us about is the Citrus Longhorn Beetle - Anolophora chinensis No guesses where it came from?
