Hoya sigillatis is part of the Acanthostemma section of Hoyas; it was described in 2004 and endemic to Borneo.
My history with Hoya sigillatis began with an order that I placed for a huge plant from an Ebay vendor from Thailand in April of 2011. It arrived with the roots completely rotted off and most of the leaves had fallen off. I managed to get a few tiny cuttings to root from this mess, but the plants never really took off and grew the way that they should have. Two and a half years ago, I traded a very nice woman in Florida a Hoya praetorii plant for some nice cuttings of Hoya sigillatis and these actually grew much better, albeit with many stops and starts. Finally in April of 2016 the plant produced a peduncle and flowered. The flowers smell very faintly of caramel and last about a week.
I don’t think I’m really the best person to give care tips for Hoya sigillatis, because of my struggles with the plant, but I have done considerable research and here is what I’ve found.
- Does not like to dry out, but doesn’t want wet soil – keep slightly damp.
- Does not like to be moved. If plant is happy, keep it where it is.
- Does best in strong to moderate light.
- Good candidate for artificial light
- Grows best as a hanging plant
- Likes average temperatures and humidity.
Overall I would have to say everyone should give this plant a go, because the rewards definitely are worth all of the effort!
