I have not previously purchased any manzurli's from Chuck, but I do have an order for a flask of Hanne Popow 'White' x manzurli 'Waunakee'. Todate I have ordered literally dozens of flasks from Chuck and my mortality rate is less than 10%. I currently have about Phrag 350 seedlings individually potted, 32 Paph seedlings individually potted and 4 large community pots (about 100-120 babies) all from chuck. I also have about about an additional 500 seedlings from Peruflora, Orchid Inn, Orchid Trading and Woodstream and all are good sources and I can recommend them completely. I love raising babies but they take work and I have spent years learning. My first flasks were disasters but that was my fault. If you are just beginning to buy flasks, purchased from reputable vendors and begin with a hardy species or cross, and do not spend a lot. Take time to learn and you will be rewarded with an amazing collection.
