Hey Julie,
I am sure that someone with some experience growing Kerrii will post. I unfortunately do not grow her at this time. I do notice that behavior on some of my other Hoyas, in particular some Carnosa. I don't think it is anything to worry about.Maybe once your Kerrii flourishes we can make some trades so I can speak from experience. LOL

Do you have any pics?

Best of Luck,
-David

Julie many Hoyas show this type of colouration on their leaves and it is natural. Some types show speckles while others look like splashes or streaks of paint than can be white, grey/silver or pinkish.

Hi David; Interesting that you've seen it in your carnosa. My carnosa just grew a solid pink leaf; it's adorable! :)

BTW, I would love to trade cuttings when my kerrii is thriving!

Hey Mike; Thanks for the input! Do you happen to know anything about what might encourage or discourage that coloring?

Thank you both! :)

Some Hoyas seem to develop the markings due to sun exposure and some of the Hoya pubicalyx cultivars in particular can develop heavily marked leaves. I grow my Hoya pubicalyx in bright light so it has fairly even markings, can't remember if shadier conditions cause less or more markings? The plain green form of Hoya carnosa has white/silver marks on the leaves while a cultivar exists called Grey Ghost that has solid silver/grey leaves because they are so heavily marked. Several Hoyas come in a plain green form as well as a speckled or spotted form and Hoya obovata and lacanosa are two that are quite common.

Thanks Mike :) I'm not very fond of it....
