All sellers write things that make us want to buy their product! I've actually seen sellers listing Carnosa as a "rare hoya"!!! With that said, my Carnosa hasn't bloomed *yet*, but I've read that it has a nice scent (like chocolate).

Keep in mind with the Pubicalyx that you will not see blooms for quite some time. They usually bloom as adult plants (at least the 'Pink-Silver' cultivar does). But I've read it has a great scent, so I'm sure it's worth the wait!

As for Lacunosa, you can easily find that in Home Depot or other big box stores, or your local nursery. And that one is a very fast bloomer. I just received a gorgeous cutting of Obscura and it has really nice foliage. It's also supposed to be a fast and frequent bloomer.

Nice choices :-)

the correct name for that pubicalyx is "Pink Silver" IF that is what you are really getting. I had both of mine, which I bought as small plants, for about 10 years before seeing a flower, and that is not unusual - could happen sooner, could happen later, but that is the average. Keep that in mind when you what you are buying is basically a rooted cutting that will take quite some time to mature into a blooming plant. For quicker results, any home depot has carnosas for sale that will bloom alot sooner, maybe in 2 to 5 years, depending on the plant size and the growing conditions you provide. Lacunosa will bloom very quickly. Maybe get the pubicalyx from ebay, then scout the local big box stores for hoyas that will give you "instant gratification". I would definately get the pubicalyx though, it is an awesome plant and worth the wait. Even before the flowers, the foliage is beautiful.

As for ebay, I don't use it and don't have any opinions about it, I have heard good and bad, so you are always taking somewhat of a chance.

I think pubicalyx are very fragrant, though mine always blooms at the same time as my carnosa, so I am not sure which one has the stronger scent. Especially at night.

Well, I don't know what I'm doing, but this is what my Publicalyx cv Silver Pink looked like last year

And yesterday
. It is very potbound, but still it goes to show it CAN flower in a year. I'm happy anyway :) It smells quite sweet at night (doesn't overpower my bedroom).
My carnosa flowered for the first time last year after 8 years of growing it from a leaf. It can smell quite strong in the evening.
Buy it if you like, just don't spend too much bidding on it if you can find it in a store somewhere!
