I have mine on a tree. It prefers to grow into the shady side. Leaves on the sunny side tend to yellow a lot. Flowers only come out on the shady side.

Thanks for the replies. I will keep the thin cotton curtain in front of it for awhile.

Bouldergrower is in Boulder, CO, zone 4-5. Tropic, where are you? You guys might be speaking totally different languages. What's sunny in zone 5 may be exact same level of light as deep shade closer to the equator. (Although Boulder's 5,500 feet elevation should also be considered.) This is why all this "full sun / no direct sun / shade" advice read online is of somewhat limited use.

I think generally, Hoyas bloom better with intense light, intense enough to bleach the leaves but not to burn them. BUT: leaves often look way better with less intense light, as I think your pubicalyx does, bouldergrower. So, what are your preferences then? You may get away with having the best of both, as the sunny side works well for the blooms, and the shady side creates nice looking leaves. I would consider not changing anything.

This hoya is at the east edge of a window facing due south with no obstruction for the sunlight. We get day after day of bright sun and I would call it intense. The leaves started looking a little burned to me but I thought that might be what they were supposed to look like. Anyway, I now draw the thin curtain at noon.

The hoya Cummingiana 'Little Leaf Bush Hoya' on the west edge of the window seems to take all the sun and water it can get and is my first hoya to bloom. Its little leaves are bright green with no sign of too much sun.

My hoya pubicalyx gets direct sunlight only in the morning, and have bright light the rest of the day... The hoya it is full of bloom, and the leaves are dark green.

What zone are you in, gen_opale? Indoors or out?

Indoor all year long. Zone 4.

I used to grow mine in a north window and it bloomed fine. Not totally bonkers, but a respectable show. I agree with Denise that I'd rather have nice leaves than tons of flowers, from this one. I'm flattered when it blooms, but it is not my favorite fragrance and it's strong. That said, my leaves don't look as nice as yours, Denise. It must be that lots of indirect light thing.

Too bad it doesn't display our Zones under our handles anymore, now that we're on Houzz. That was handy... ¬_¬

Yep, I'm a leaf-gal too. Boudlergrower, I would move it to a bright position that won't wash out the leaves. It'll bloom when it's good and ready. Mine in the GH, which was over 3' wide AND 3' tall, went to plant heaven about a year and a half ago. (My mom says, "Kiddo, plants die of old age, too, I'm sure!) And it WAS old. But I took lots of cuttings when it started it's decline and 'PS-2' is nicely established and will hopefully bloom in the next couple of years. (And getting on the large side already!!)

But you're right, GG, the fragrance is overpowering. I call it musky, and I do like it, but it can choke you if you have too many flowers at once! I don't complain about it being a stingy bloomer!

lol musky. Yeah, sometimes I just don't even know how to begin explaining what makes a Hoya fragrance less than wonderful. I never knew a garden flower to have such dramatically weird perfumes. They remind me of an overenthusiastic perfumer apprentice running amok with their experimental combinations.

Yeah... they do die of old age. It seems like they should be immortal if only we don't screw up in our capacity as caretenders. I wonder why it is our gut instinct to see plants that way, when we know our animal companions don't live forever either.
