This one started my Hoya craze. I bought it as an Exotic Angel hanging basket from Lowe's. It is a cute plant but I bought it because of the rave reviews about the scent. Promises of a beautiful, wafting fragrance similar to hyacinth and carnation. Well, it smells similar to those flowers but the smell is not very impressive or pervasive. I can pick up a light scent when standing next to it but it's nothing to get excited about. I do have it outside and it has acclimated quickly to the strong Florida sun. I'll keep it for now because I have no one to gift it to and it is growing pretty well.

I've had this plant for four years now and it is my favorite of all my hoya plants. I live in Central FL zone 9b and we can get pretty cold in the winter. I can say the plant does okay down to about 46F for a night or two, but too many nights in the lower 40's will cause damage, unfortunately I found out the hard way. I keep mine hanging outside all year long in the filtered shade of an oak tree, but it will get some full sun in the winter months. Too much sun will burn the leaves. I give it orchid fertilizer when I think about it. The plant blooms all year long, even now in January I have well over 26 flowers on it and they smell wonderful. I do water with rain water from my rain barrel when it completely dries out.

For those growing this as a houseplant in the Pacific Northwest, it flourishes in a west/southwest-facing window.

Of 7 hoyas I have, lacunosa is the only one to bloom reliably.
It often blooms lightly in February and ,once the warm humid weather of SE New York State comes, pretty much continually. The scent is like cinnamon/hyacinth, and powerful. This plant needs humidity in the air more than heavy watering. DO NOT pull off the old blooms- the new ones sprout from them.
