All I could do was to wait until it flowered to find out if what I purchased was really Hoya chloroleuca. Fortunately I did not have long to wait. I got my first peduncle at the end of June, which did not bud up, but it grew another peduncle in July, and budded up with only four buds, but that was enough; it flowered near the end of August only four months after receiving it. The plant was clearly labeled correctly, and I got my green coronas!
