Thanks for the info, Geof! I thought the black edges might be from fungus. Most of what little rain we've received has been on the warm, humid evenings or nights. I know that isn't the best time for it. I have trimmed some off and seen improvement. I've read articles in agreement with what you say about the yellow veining possibly being a nutritional issue. I guess that's why some of the suppliers I've read about wait until well into summer before deciding to rip out a plant. I've had a few of these in the past that have lived and bloomed normally. If it is a virus, I wonder if it can spread from plant to plant without help, i.e. insects or cutting tools?
