Revised 9 Mar 2008
ASCLEPIAS is a genus of Tropical American small shrubs - the basis of the family name. Plant in good soil, in strong light, keep in the open garden during good weather. Monarch Butterfly caterpillars love this one for dinner!
curassavica, L. A- THE BUTTERFLY BUSH. 1/2", brilliant orange and red flowers; 15 - 20 in umbel; leaves lanceolate on a moderate bush. Tropical and semitropical, worldwide.
CALOTROPIS is a genus of tropical shrubs or small trees. Flowers are heavy and thick with a tall corona. Need room and good light. Grow on the dry side. This is not a house plant.
gigantea, R. Brown A- CROWN FLOWER - Either white or lavender, 1" flowers; leaves large, silvery green on a large bush or small tree. Used in lei making here in Hawaii. India-Burma
CENTROSTEMMA is a genus of tropical asclepiads quite different from Hoyas in that the corona is high and pointed, with the inner lobes pointing up and the outer lobes reflexed and spreading. This arrangement makes it look like a SHOOTING STAR. These plants are all tropical bushy plants and need the same treatment as Hoyas. Well established plants can reach 6 ft. across (as I saw at Danum Valley, Sabah, Malaya). This genus is sometimes listed as a section of the genus Hoya.
multiflora, Blume B-SHOOTING STAR. 3/4", white and buff flowers with corolla bent backwards; 20 in umbel; leaves thin, 5", with or without gray splashes, on a husky bush. Malaya-Philippines-Borneo. Some consider this to be a Hoya; I dont, so it is back in the proper genus.
DISCHIDIAS are tropical, epiphytic vines that are nearly all myrmecodial (ant harboring). They do best planted on a slab of tree fern or in a basket with a loose mix. Keep in 50% or more sunlight, 50F minimum temperature and 50% humidity. The flowers are all urn-shaped with the top of the corolla split for about 1/4 of the depth, creating 5 small petals.
The shingle (imbricate) types must have support otherwise the new leaves will curl up and be much smaller. Ants live under the imbricate leaves.

HOYAS are either tropical or subtropical, terrestrial or epiphytic, vines or shrubs. It is best to assume that they are all epiphytic and grow them in light mixes with good drainage, moderate light and a minimum temperature of 50F (10C).
About Eriostemma Hoyas This is a separate genus (Eriostemma) according to some botanists - separated from Hoya by having certain characters - the most obvious being the free-standing column that stands in a hairy "cup" at the point of attachment with the corolla - (eriostemma) means wooly crown in Greek). They are terrestrial vines and like alkaline conditions. Most do not flower until they reach good light and ventilation - usually, at the tops of trees; for this reason, they may not flower under greenhouse conditions with low light intensity and stale air.

VARIEGATED HOYAS - I have been asked if I have any variegated forms of Hoyas or Dischidias. I believe that light intensity greatly influences the percentage and extent of variegation (and the introduction of pink and red) . Also, I have found that those forms that are most variegated are usually the hardest to root. Here are some of the ones that I have.
Photo 1, H. acuta, Photo 2, H. australis, Photo 3, H. australis, D. nummularia, Photo 4, H. kerrii, Photo 5, H. carnosa, Photo 6, H. latifolia.

Just got back from a return trip to Borneo (2/7/08) and this time my wife Dorothy, Carol Noel, Rudy and Anne Bachmann went with me. It was my 9th time there, Dorothy's 2nd and first time for Carol, Rudy and Anne. Of course Sabah is changing, more forests being planted to Oil Palms and pulp trees, more housing, paved highways but still I am amazed at the place. Within the forests that remain, - the valleys, mountain tops, river banks - new Hoyas are being found every year.
There are now 2 local people there who have good collections of the native species of Hoyas and doing a good job of raising them - one collection is at sea level (hot) and another at 1500ft (cool). Both are within 30 minutes of Kota Kinabalu. More people are getting interested in hoyas - so much so that Tony Lamb is starting on his book of the Hoyas of North Borneo.
I did find H. nyhuusiae and H. telosmiodes on Mt. Kinabalu (no flowers) but not H. gildingii and, even though I really looked in Sipitang, no H. spariodes. Houses are now built where we found it before.
The Hoya Garden at Tenom is suffering - too much shade from the overgrown trees, lack of funds and someone with a Hoya appreciation to look after them.
This Feb-March '07 trip to Palawan Island, Philippines, was a social/touristy success for Carol Noel, Rudy and Anne Bachmann and my wife Dorothy and me but a failure for collecting, zero, zilch, nada! It is amazing how the areas have changed in the past 7 years and I didn't find a single H. imperialis or D. imbricata in places where there were many before. We didn't find H. curtisii and H. darwinii at St. Paul's Bay. Everywhere was warm, dry and dusty but no rain, few mosquitoes and no leeches.
On Luzon, we did get a chance to visit Dr. Monina Siar at the University of the Philippines at Los Banos and see her hoya collection. Her building has burned up since we were there and much valuable research material was lost.
My mother-in-law's death in Australia interrupted our trip back to Palawan Island in the Philippines in February and we couldn't make it back ($800 increase each in air fare) so we gave up. So, we went to Fiji where we were successful in collecting all 4 of the Fijian species: H. diptera, H. vitiensis, H. australis and the long sought after H. megalantha. We found them all within a 20 mile stretch on the island of Taveuni. The H. megalantha we found in the exact place where I had searched 3 times before, at 3,200 ft., but this time there was ONE, wilting flower still in bloom (end of the season) and that lead me to a whole group of the plants. You should have seen this 84 year old climbing a 25 foot cliff above the road to get it!
We also found, H. diptera, H. vitiensis and maybe H. megalantha (no flowers) part way up (at 2,700 ft.) Mt. Victoria (Tomanivi) on Viti Levu. That hike was easy compared to climbing that cliff on Taveuni.
In July (2006), I went back to the Philippines to see Monina Siar and her hoyas at Un of Phil Los Banos and Rolita Spowart's orchids in Manila and then continued on to Sabah (6th trip there) to see Tony Lamb, the condition of the hoya garden at Tenom, and collect a few things. The Tenom Garden is going down hill for the trees are making too much shade and funds are short so the maintenance suffers. On the other hand, H. campanulata, without any care, is now 6 ft. across - grown from a small cutting that I brought back from Danum Valley, years ago. Did see some fabulous H. imperialis flowers, in a private collection, nearly 3-1/2" diameter! - the grower uses horse manure for fertilizer! It was a quick trip and wished that I had more time to go to Banggi Island in the north. Maybe next time.
Still, there is a prize waiting for the first person who gets H. glabra to produce a leaf greater than 9 x 12. Send a picture!
The best laid plans of mice and men - Some hoyas do not perform as we hope. Hoya gildingii and Hoya nyhuusiae, interestingly (what I thought were un-hoya things) that we collected on Mt. Kinabalu, Sabah.. Incidentally, these honor 2 of my collecting buddies - Ed Gilding and Torill Nyhuus! I think that 5,000 ft on Mt. Kinabalu is too high, too cool for my conditions here.
