Hoya Krimson Princess Leaf Color Question
This has probably been covered but I thought I'd ask up front. I've had the mama plant since 2012. It has doubled in size since I purchased it. It hangs on the front porch (east) from about mid-March through the second week in October (warm, zone 7A/B). It DOES bloom (usually in July and August). It spends winters indoors about six feet back from where it summers (same exposure, but shade trees are bare so it gets almost the same sunlight levels all year long). My question has to do with the leaf color. All new growth upward seems to be green and all growth downward seems variegated or pure cream/white. Is this normal for this cultivar? Does it need something else? I fertilize it with Foilage-Pro during its spring and summer growing season. I've taken many, many cuttings from this plant, both for myself and to share with others. I'm including a picture of last year's cutting, which was under plant-spectrum LED lights all winter. It seems to have a lovely red color that I am hoping it keeps now that it has been moved outdoors. Anyway, I am hoping to amend what I'm doing with mama plant to encourage and foster more even-colored (variegated) growth. Hopefully someone has some suggestions. Thank you in advance.

It looks 100% fine to me. 'KP' tends to revert back to all green. You can do one of two things - you can either leave it to grow into a green plant, or like most of us, remove the all-green shoots as they grow. I wait for them to have several leaves, remove that vine and root it. The rooted cuttings make the most beautiful clone of green carnosa IMO...

It looks to me like you're doing everything right. It's beautiful!!

Original Author11 years agoThank you, Teisa! :) I just wish she was more white. I wonder how they are so evenly colored when offered to sale, then they start making more green new foliage than cream. Is it light level? If so, I can affect that to some degree. Anyone know the reason? Not that I have anything against all-green hoyas; I love them, too! But, I just really love the cream leaves. Her baby is producing some cream leaves but, as you can see in the picture, it's mostly green.

Original Author11 years agolast modified: 11 years agoUpdate: This mama plant bloomed early this year (it's been rainier and cooler than average this spring and into summer), which may be contributory. Unlike my other Hoya carnosa variants, which bloom more pink, this one blooms almost white (same chocolate-like fragrance). The good news is that this plant's new growth is now all variegated (pic below is an example of a vine with new growth but it's like that all over the plant), which I'm utterly thrilled with. I'm still really curious how when we buy these plants, the commercial nurseries where they come from are able to achieve this all-over variegation but when we continue to grow them at home, they start growing all green (like my mama plant did for all growth upward). I just am trying to discern what the variables are that cause the variegation. It can't be sun intensity because this plant is growing on my covered front porch on a shady lot (and its cuttings grow variegated leaves no matter where they're placed, inside, outside, and under plant lights). If anyone knows the answer or has a theory, I'd love to hear your thoughts. This is one of my favorite plants and I would like it to stay as variegated as possible. I haven't yet removed any solid green leaves since as soon as I posted my original post, it started growing variegated leaves again. Mystery. :-)

I guess I always assumed that, at the nurseries, they trimmed off the reverted vines, when they saw them. Often, I still see plants of KP for sale at BBS that are 50% or more reverted.
If the vine has variegated leaves, and then starts growing some pure green ones, you don't have to worry about pruning them, because they will typically start growing variegated leaves again further on. It's the vines that are pure green, with zero variegated leaves, that are less favorable (if you want to maintain a strongly variegated plant). So, maybe the vines you were worrying about earlier, were the former case. Sometimes my plant goes years without one of those reverted vines, and then stubbornly produces one after another. Maybe they are responding to environmental conditions. I haven't heard of anyone providing strong evidence for a factor, though, the way they have with variegated African Violets.

Original Author11 years agoThank you, GG, for your sound theory on that. Alas, it's probably far to late to start whacking all the solid green vines, which, interestingly, seem to be all vertical growth; while downward growth seems to be maintaining the variegated growth, which I prefer. I think I'm just going to let it "grow wild" and be happy that at least half of it is variegated. I have several of this plant's cuttings that are between brand new cuttings to several years old. I think I will start applying your suggestion and start cutting the solid green vines on those and kind of play with it and see how that develops.
I'm also really interested in what encourages more variegation in hoyas. Some growers swear it's dappled sunlight; some swear it's bright, full sun. Mine is on a pretty shaded porch, facing east up to 8 months a year. It's growing the most variegated leaves on its shady side of the porch. Thanks for sharing your thoughts and hoya knowledge. Greatly appreciated.

Amazing plant, I am so jealous! I wanted to ask what size pot is that, and have you potted up?

Original Author11 years agoOkay, I took updated pictures of both mama plant and her year-old cutting. If it matters, this is a non-Exotic Angel's plant.


Still curious about what makes, maintains, encourages, or eliminates the variegation.
And in that vein of thought, here's my Krimson Queen. It was a baby this year and has grown quite a bit. It's out in almost full sun (some oaks provide shade for part of the day). I just love the all-white leaves.

All the variegation being on the shader side gives you your answer.
The plant wants more sun so it is putting put all green leaves (more chlorophyll) on the side where the sun is to make more food. They keep them highly variegated by keeping them in very bright light (but not intensely hot like the sun!)
My neighbor's marble queen pothos did this and she didn't understand why the only small marble queen vines left were the small ones crammed behind the plant between it and the wall, completely away from where the sunlight comes in.
**Editor's Note** this also explains why the green is growing up towards the sun and the variegation is growing down. **END EDIT**I would try to take all the variegated vines and try to root them beside the mother plant (or below her, it may be difficult lol) while still attached. Once you see they are rooted and putting out variegated, new growth, pot them into their own pot of KP and let the green monster have the 8 inch pot lol

Has anyone successfully kept one of these variegated? My plan is to snip off any all-green or even half-green (split down the middle, you know what I mean, green on one side, variegated on the other half).
My theory/hypothesis is that this will make the plant "think" that having more green in your leaves means they get "eaten" and so are a waste of resources. Kind of like tricking it into thinking the variegation protects it from predators by making it look poisonous or something like that. You know....nature stuff.

Original Author11 years agoLet me know how that experiment goes. I'd be interested. Yeah, noted, it's more variegated growth is on the shady side of the porch (and I don't rotate it), so that's probably a big key with this particular plan (ironically, my KQ is in almost full sun and is the one with the most variegation, including solid white leaves). Mama plant is too big cull all the all-green leaves; it would just leave her too bare. But, I am able and willing to try that with her very variegated yearling cutting (that is already a small plant). Yearling has quite a few variegated leaves but I think I will remove any solid green vines.

Actually, I don't think it's a matter of light. I think 'KP' is an unstable sport of carnosa. I'm sure a botanist could explain why some plants are like this. Have you ever grown a crested Euphorbia trigona or ingens? Sometimes, you'll get a shoot that is perfectly normal growth, which most people promptly chop off. I've had this happen with other crested or monstrose succulents. The variegated forms of carnosa (and other variegates, for that matter) are a sport of the original green form. (Google "sport in botany" for a better explanation that's more technical than my non-science mind can give!) You whack off the "sport" or mutated growth and start a new plant in hopes that it will continue to grow that way. 'KQ' is a very stable sport - I've never seen it have reverted vines. 'KP' on the other hand is not stable and every one I have ever had eventually reverts back to all green. Well, actually, I'm growing one right now and so far, so good. However I will add that it's the first time I've ever grown one in a north window where it gets NO direct sun at all... Another reason I don't think it has much to do with the amount of light...
Oh, and GG, I have a massive pot full of green shoots from the 'KPs' I've grown over the years and not one has ever produced variegated growth, so apparently once you sever it from the variegated plant, it will no longer produce variegation! I think it's very interesting that on the plant, it can revert to all green, then go back to variegated! Don't ya love plants?!

Original Author11 years agolast modified: 11 years agoThanks, Denise, for the interesting background on KP and KQ sports of carnosa. I had never read anything like that so it's good to know. Explains the frustration of the reversion despite various growing conditions. However, my big mama plant is a strange duck all by herself. All growth downward, including new growth this year, is variegated and all the vines growing upward are fully green. The time to prune those is long past, so I'm just going to enjoy her unique two-toned look (I'll tell visitors I did it on purpose LOL). I have her yearling plant (pictured in pictures above) that I'm going to experiment with. So, on the same vine you have variegated and green leaves, do you remove just the green leaves or do you cut the entire vine back to the last variegated leaf? This plant seems to be doing one green leaf, one variegated leaf and so forth.
I really do prefer the KQ variety of this hoya. I'm going to baby my baby one and try to get it to impressive-specimen size. The all-white leaves are really pretty on that plant.

this poor hoya princess has been through a rough year with me lol i work at a plant nursery and tend to bring home more than i want to care for, but ive gotten her leaves stiff and healthy again and noticed her first new growth is dark burgendy trimmed in black? i cant find a red and black leaved hoya anywhere online?
- 4 years ago
Kristy Somerville, some hoyas new growth will be those very dark leaves when they first come on. As the new leaves mature they will get lighter and become the "normal" leaf color like the rest of the plant. I've noticed it especially on my Pubicalyx
- 4 years ago
has anyone figured out why they revert?? how to get more stable sport variegation. It has nothing to do with light. I have pushed one of mine to the brink trying to get more variegation out of it with more light. Even burning it slightly. Slowly acclimating until it can't handle it anymore. I have one that ALWAYS produces variegated vines regardless of lighting. Not one is green. I have another one that does occasionally. Good news is it will go back further down the vine eventually. I can add some pics if you like to show you! I am not as experienced as any of you. Just another hoya lover! Expecially the queen and princess.. It must have something to do with the DNA of the mother plant they were taken from. At least that is what I think. lol.
