My hosta has this puckered looking bubbles on them. I am wondering if it could be due to the very late cold/ice we had in April (SW Missouri, zone 6). They were already starting to leaf out a little and I wonder if that caused it or if I have something else going on. I don't see any pests of any sort causing this. It's just one this one variety, not my others. Some of the others suffered damage but they were leafed out farther along and just turned to mush.
