ASCLEPIAS is a genus of tropical and semitropical American small shrubs - the basis of the family name - Asclepiadaceae. Plant in good soil, in strong light, keep in the open garden during good weather. Monarch Butterfly caterpillars love this one for dinner! Breakfast?
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 C- CROWN FLOWER - Either white or lavender, 1" flowers; leaves large, silvery green, partially fuzzy, on a large bush or small tree. Used in lei making here in Hawaii. India, Burma, Indonesia
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, Malaysia). 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. Malaysia-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 the urn with 5 small petals.
The shingle (imbricate) types must have a nearly flat support otherwise the new leaves will curl up and be much smaller. In nature, ants live under the imbricate leaves that are attached to the support.

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 - and are separated from Hoya by having certain characters - the most obvious being the free-standing hairy column that stands in a "cup" at the point of attachment with the corolla. Eriostemma means wooly crown in Greek. IN THIS LIST THEY ARE SHOWN AS HOYAS. They are all vines and like alkaline conditions so add oyster shell to mix. 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 house 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.
NEW I have some Hoyas that are still unclasssified, although several have bloomed. Most have interesting (medium to very large) leaves or great potential for interesting flowers. I am offering 10 of the following and are sold only as a collection for $100. I am sure that under someone else's growing conditions these will bloom and be classified but don't expect large blue flowers with yellow dots!
1 H. sp. IV From WMZ
2 H. sp. Palawan-div, From the Philippines
3 H, sp. Robinson Power Dam, from Peninsular Malaysia
4 H. sp. MM macgillivray? hybrid?
5 H. sp. IML 1139 An Eriostemma From PNG.
6 H. sp. Book Village
7 H. sp. Hevola, An Eriostemma From ?
8 H. sp. I, from WMZ, in salweenica complex
9 H. sp. 900307 JP From the Philippines
10 H. sp. Anthony, from the Philippines
TELOSMA is a genus of tropical vines that demand the same cultural conditions as Hoyas. They should be treated as terrestrials and, this one offered, should be trained on a trellis. This is not a house plant for it needs a lot of light and room. These plants are not easily rooted.
cordata, (Burm f) C- 1/2, chartreuse, bell-shaped flowers; 8-l0 in umbel; leaves round, cordate, 3", dark green, thin, on a wirey, very robust vine. This is the Pakalana (or Chinese Violet) of lei making. A beautiful fragrance! Need a lot of light to do well. China-India
sp. Guam C- 3/4, light green, bell shaped flowers with twisted corolla with pointed tips, 15-20 in umbel; leaves 3-4, medium green, on a robust vine. Flower not fragrant as cordata. Guam
WHATS NEW - WHATS COMING UP -
Dorothy and I went back to Singapore and Peninsular Malaysia in Feb '14 to visit gardens, people and do some photography (no collecting). How things have changed - "improvements" are definitely not always improvements. I liked the way Singapore was in 1963 and the old colonial E and O Hotel in Penang of 25 years ago or the colonial hotel on Mt. Jerai - of 10 years ago. Saw the biggest H coriacea vine yet on Mt. Jerai! This was a bucket trip for me.
Dorothy and I went back to Sabah in April '12 (my 10th trip to Borneo in 21 years) and saw new things at the Butterfly Farm at Kipandi. A social trip just to see what is happening...Hiking told me that I need a right knee replacement.
Went back to the Philippines and Sabah, Malaysia, Malaysia in April 2011 - to see collectors around Manila and then on to Sabah, Malaysia, Malaysia to plant out tissue cultured H. spartiodes in 3 places, where it is very rare. Also, to visit collectors and friends. I went alone and always hate traveling alone.
I went solo to Micronesia in May 2010, to collect the true H. schneei (since most of the ones in the trade are H. leucorhoda) and to try to collect H. trukensis (which I have never seen). Found the H schneei but not the H trukensis - wrong island in the Truk group - This was a very expensive trip!
Add another trip for Dorothy and me, April/May 2009, when we did see H. nyhuusiae, H. gildingii and H. telosmiodes on the Crocker range (no flowers though). Unfortunately, we did not see H. spartiodes, in Sipitang, even though we really looked. Houses and a school are now built where we found it before. The Butterfly Farm is getting better and better, with new hoyas and collection of things not found previously in the area. Mt. Kinabalu is still one of my favorite places and the Kiau View Trail the best hike, pleasant and cool - heaven on earth!
Made a return trip to Borneo (on 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, Malaysia, Malaysia is changing, more forests being replanted 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 in Sabah, Malaysia, Malaysia 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.
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. The Mountain Garden on Gunong Emas has nearly all been lost - deteriorated and died from neglect and fire - what a shame!
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 photography, 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.
On another trip back to Fiji, Dorothy and I saw H. diptera, H. vitiensis and H. megalantha on Taveuni and maybe H. megalantha (no flowers - turned out to be a yellow H vitiensis) part way up (at 2,700 ft.) Mt. Victoria (Tomanivi) on Viti Levu.
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, Malaysia, Malaysia (6th trip there) - to see the condition of the hoya garden at Tenom. 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. danumensis, 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!
Some higher elevation hoyas do not grow that well for me Hoya gildingii and Hoya nyhuusiae (T. Nyhuus photos), both from the Crocker Range of Sabah, Malaysia, Malaysia. Incidentally, these honor 2 of my collecting buddies - Ed Gilding and Torill Nyhuus! Photos by Torill Nyhuus
