Habitat is distributed in secondary tropical evergreen broad-leaved lowland forest on sandy soils in coastal areas in Quang Tri and Nha Trang, Vietnam.
Unfortunately, what the vendor sent from Thailand did not match the descriptions of what was supposed to be sent. The photo below was supposed to be Hoya hanhiae ‘Yellow’:
Obviously it is not yellow but a very dark pink. Below was supposed to be Hoya hanhiae ‘Yellow Pink’ which once again does not match up with the photos online.
I ordered a third color, which has not flowered yet that was supposed to be Hoya hanhiae ‘Purple’, but who knows what I will get with that one!
It has been a while since I’ve extolled the benefits of using at least one grow-tent if you live in a cold climate like myself. Grow-tents are available in all sizes, and there is one to fit into even small spaces like a closet. With them, it is possible to completely control the plant’s environment from temperature and humidity to lighting and day-cycle. I could not do what I do without them; this display of cut imperialis flowers in December would be an impossibility.
People have told me that they like to be able to see their plants. Well most of these tents have clear windows that can be viewed if one wishes. The largest tents will let one go inside where you can spend time with your plants in a tropical environment. A greenhouse in my area of the country would be prohibitively expensive to heat throughout a winter, but a grow-tent is much more affordable.
Hoya lockii will not be lost to me any time soon as I have a large number of plants now, and for the most part, they all look good. They are quite happy growing in sphagnum moss mixed with a little bit of bark. They all grow in well-lit, warm, grow-tents with day time high temperatures of around 77°F, and Night time lows of around 60°F. I have enough plants now that I may try moving one into the regular house and see how it does for me. I think it may surprise me as its close relative H. papaschonii is doing quite nicely upstairs in a dark northwest window. The entire secret was discovering that it likes to be constantly damp in sphagnum. Here are a couple of close-ups of the flowers from a few days ago:
Here is a photo of a very happy Hoya lockii in the middle of December in Vermont. I don’t want to say I know how to grow this one now as the last time I said it, the plant went down hill in a hurry. Tomorrow I will talk a little more about the conditions under which it grows and how I’ve ensured that I will have this plant for a long time to come.
