Here's something interesting. This is the Slaughter Pink. This is one of my older plants and it has never had this color change before. Until this week, all the blooms were typical, but now all the new flowers are showing this change. What's going on to cause this? Its not like this tree has been through the heat of summer before.

How do you like this cute, fat, white spider? It does show quite a contrast with the green one I photographed last week.

Ken the 2nd, 3rd and 4th pics look like a virus to me. You might want to separate that from your collection and don't use the same cutting tools you used on hat plant to the other plant.

The white spider look cute.

I wish I understood more about viruses but I simply don't. This is a well established plant that has always bloomed like the typical S. Pink. Even just last week the flowers were true. Does a virus change flowers practically overnight? The plant looks healthy and the flowers are typically formed, just with that color-shift. I don't know.

I think the change can come quite quickly. I had cannas that were fine, but suddenly changed and are now virused.

According to someone who is supposed to know more than I do about this, this is called a "splash" and is very common in plumeria. She stated that Slaughter Pink is well known to display these color shifts. She said that plumeria color genes are unstable and this causes "splash" like this to occur. often when there is some stress, such as very hot, humid climate. She said I could see this even without stress conditions. She further stated that unless I see viral changes in the leaves and particularly see that the plant is in decline, it is not virused.

I am attempting to understand this and have contacted the PSA. Unfortunately, that site doesn't seem to have a way to submit photos. Hopefully, someone with expert knowledge will contact me via email and I can send him/her the photo for evaluation.

Can someone please explain "Virused" plants to me?

I have had a plumeria blooming since Mid May when the first bloom opened. Each bouquet is a little more deeper pinks than the next. Does this color change constitute a "virus"? They are still pretty as are @drdawg 's flower color change.

Several folks on a Plumeria site on FB said that the flowers are gorgeous and love the color-shift. One even said they were orchid-like. That's what's so confusing. Some say "Oh, oh, time to trash it" and some say that the flowers are great. I sure hope the PSA comes forward with some real expert information.

Thank you, Hetty, @dutchlady1. That was a good read. I am going to have this plumeria virus-tested. I will contact AC Diagnostics, Inc. and ask what they need.

I am waiting to hear back from the PSA, but am not holding my breath that anyone will respond.

In case anyone wants to know, that statement from the lady about splash petals being relatively common came from a lecture presented at the International Plumeria Conference by Dr. Richard Criley, horticulturalist of the U. of Hawaii. I have tried to find a way to contact him but haven't found contact information yet. Hetty, I think you presented a workshop at this Conference, right? If so, do you know of Dr. Criley and did you attend his lecture?
