Hi there! Just was wondering what the spots might be on the leaves of my hoya subcalva... I bought this plant from logees a while back and had a subcalva in the past and it didn't have the white speckles on the leaves like this hoya does. And another strange thing is that the subcalva that I used to have would also bleed a white milky sap if a leaf was damaged while this one doesn't bleed at all. So I guess question number two would be if a specific species of this plant could be so variable in terms of its makeup or if perhaps this may not even be a subcalva... Anyways thanks so much and as always I'd love to hear anyone's ideas.

Hmmmm. Don't think it's mealy bugs... those spots are permanent and rubbing them with a cloth and alcohol didn't remove them at all. It looks like paint splashed on the leaves or something. I'm thinking it's just normal for this plant since new leaves always show speckles once they mature. I just wonder if I really have a subcalva or another species of hoya 😐

Do the spots rub off? If not, I would consider this a variation of the plant. I don't know how long ago you had your last Hoya subcalva but plants change. And its all our fault. People choose the plants from any give species that are unique. So over the years, the plant that you thought of as H. subcalva may not be the current version of H. subcalva.

Mine has spots too. It has always had spots and I just figured it was the way it is. It doesn't get worse or better, doesn't seem to affect the plant at all so I think they just have spots naturally.

Thanks. I figured it was normal. The plant does appear happy. Hopefully the grape fragrace is the same though if it is indeed a variation (since subcalva flowers are said to smell like grape juice :). This subcalva is quite different from the last which is interesting. The last one had milky white sap and would drip sap if you accidentally bumped a leaf and injured it while this one has clear sap but doesn't really bleed at all...

Hmmm... I had to go sacrifice a leaf on one of my Hoyas. No white sap.

Very interesting... isn't that weird? From what I've heard (can't remember the source) most hoyas are supposed to have milky white sap and it's apparently rare for them not to. My obscura and another hoya both have the white sap as did my old subcalva so its ironic my new one and yours doesnt. Although I really don't mind since the white sap is messy and stains anyways ;).

Those marks reminds me of one Hoya I used to have, Hoya pubicalyx 'Silver Pink', it has those light spot variegation..too bad I have killed it a couple of years ago. But I do not know all Hoyas, but some do have those specks:

Kathy, taking them to work is not a killer setting for them Hilarious! ...but I left one of them outdoors during winter, thinking it can manage it, my bad..it was one of those winters when we got too cold in the 20F's overnight and then some rains a few days later...very bad combination for it.
