How Hoya paulshirleyi Got Its Name

Paul Shirley operates a web-based nursery in the Netherlands called Paul Shirley Succulents.  He ships plants all over the world with the exception of the U.S. and Australia.  In 1994 Paul joined Ted Green and Dale Kloppenburg on an expedition to Sulawesi, Indonesia and they discovered a number of new Hoya species.  Eventually the plant that Paul found and gave the accession number GPS 8845 became Hoya paulshirleyi.

Growing Hoya paulshirleyi Part Two

Hoya paulshirleyi needed to be watered well a couple of times a week and grew quite rapidly.  I was quite surprised when I spotted the first peduncle so early.  From Cutting to flower only took around six months – Keeping in mind this was grown in ideal conditions of artificial lighting in a grow-tent.


Growing Hoya paulshirleyi Part One

Hoya paulshirleyi rooted very quickly and I ended up with two plants salvaged from what looked like a hopeless cause.  I grew them in net pots using my standard chunky mix.  I found out quickly that this was a plant that drank up a lot of water.

Time to Look at Hoya paulshirleyi

I received Hoya paulshirleyi in an ill-fated group order from Thailand in September of last year.  The roots were completely rotted off so I took several cuttings to see if I could salvage anything, and I ended up with two plants.  Below the first flowers of the plant:

Final Day with Hoya curtisii 2018

I love Hoya curtisii.  It is common and easy to find; the leaves are spectacular, and if you get it to flower, you will feel like just maybe you’ve got this Hoya thing figured out.  If you don’t have the plant, pick one up, you won’t regret it!

Care of Hoya curtisii Part Three

Now that we have touched pot, soil, and watering, it’s time to talk about light and humidity.  Hoya curtisii will grow well in full sun or very little sun.  It is pretty adaptive.  I flowered this plant the first time after having it exposed to full sun out of doors for a full summer.  The second and third time it flowered just as the days were beginning to lengthen in late February/Early March indoors in a northwest window with almost no sun.

There is no doubt that Hoya curtisii grows best in high humidity, but it will muddle along with relative humidity as low as 40%, but expect a lot of dried out growing tips.  My plant lives year around now in my house witch gets pretty dry in the winter time.  I think think this Hoya would like to live in a bathroom where it would get extra humidity from people taking showers.

Care of Hoya curtisii Part Two

Now that we have the soil and pot figured out, how about a watering schedule? I have found the schedule should be thrown out; this plant needs to be only watered once it has dried out.  I’m a person who likes to water all of my plants on the same day each week, but with Hoya curtisii it won’t work.  Water only when dry, then soak the plant, and start the process all over again.

Care of Hoya curtisii Part One

There is much advice on the internet about how to care for Hoya curtisii from never let it dry out to keep it dry all the time.  I can only say what has worked for me. The plant needs a relatively small pot where it can literally live for years (Mine has been in the same 4 inch pot for 4 years!). The soil should be relatively free draining, but also have some water holding capacity.  Peat-based potting soil amended with 25% perlite should work fine.
