Purchased eight of these promising sounding Invincible Wee White hydrangeas direct from Proven Winners last spring since it was only available from PW direct at that time. All of them arrived with the tiniest appearing pinhole sized leaf blotches which didn't concern me at the time. Most plants from any source don't arrive without some sort of blemish. I don't go immediately bonkers over what looks rather normal. Within an alarmingly short period of time - like a matter of days - the blotches rapidly spread- all of the Invincibelles wilted and rapidly died, despite being immediately diagnosed and treated with recommended fungicide from the leading nursery in our region ( who does sell Proven Winners) it was too late to get the info to Proven Winners, who of course assured me only the healthiest plants to me - but all of the plants there had no problem. I discovered the best and only "treatment" was to dispose of the infected hydrangeas. The fact that all of the PW order was of the same plant arrived with the same problem and had the same outcome really sets of an alarm that there must have been a problem on the other end, which is Proven Winners. My loss was in the hundreds of dollars and I will never ever trust this brand ever again.
The Proven Winners customer service rep I contacted seemed pleasant enough but really proving the plants arrived that way was impossible. Oddly enough not one of the literally dozens of shrubs and perennials that the plants were next to while hardening off before planting had the same problem. Seriously - dozens of both shrubs and perennials hardening off in the same area and only the PW shipment was affected or died. Did not lose a plant of any species from any other supplier.
If this would have happened with my local garden center here the issue would have been dealt with with an immediate refund and they probably would have isolated every one of these plants and dealt with the issue seriously. I see that the same Invincible Wee White hydrangea is being sold and seriously wonder how many other customers shipments of this plant were affected similarly. Am I bitter about the situation, you bet! Won't ever purchase another PW cultivated plants from any source ever again.
