Revised 1 April 2022

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" heavy flowers; leaves large, silvery green, partially fuzzy, on a large bush or small tree. Used in lei making here in Hawaii. India, Burma, Indonesia  This is really not a house plant.

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.

benghalensis, Coleb.  C- Very small white flowers; 2-3 in umbel; leaves are thick, nearly always terete on a wild, scrambling, pale (nearly gray) vine with long internodes. India to Malaysia

imbricata, Warb.     C- Small yellow and white flowers; 5-6 in the umbel; leaves 1", growth like diphylla but dark green. Needs support (shingle-stacked leaves). Malaysia-Thailand-Indonesia Must be planted with support.

lutescens Zipp.      D- As major but with egg-shaped, 2.5” saccate leaves. Timor Must be planted with support.

major, (Vahl) Merr. D- Medium yellow flowers; few in umbel; leaves either flat, 1" or saccate to 4" tall, hollow, light green. See in Exotica III. An ant hotel. Syn rafflesiana. Malaysia to Australia This is a xerophyte. Must be planted with support.

var. IPPS 35    D- Same as typical form, except the saccate leaves are 6" tall and quite flat. Another ant hotel annex - for skinny ants. Don’t know country of origin.  This is a xerophyte. This is a weirdo! Must be planted with support.

nummularia,  Brown C- Small white flowers, few in umbel; leaves very small and thick.  This plant gets to be so big and heavy that it makes trees collapse in Malaysia, where it is from. This is a succulent but lives with high humidity. Best planted with 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) - and is 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. polystachya.


Here are 2 collections - set one - 8 Eriostemmas and set two - 8 odd leaves.  Some are straight species. some classified and some are hybrids. I am offering them as set One or Two and are sold only as a collection (not mixed) for $100. These should be interesting for both the beginner and the collector, most have bloomed BUT none with large blue flowers with yellow dots!  


H. affinis, H Gold Star, H. ciliata, H. obtusifolioides, H. Isabella, H. Ruthie, H. Optomistic. H hollrungii


H. merrillii, H brevialata, H , H acuta var, H heuschkeliana, H  pubicalyx,  H tsangii, H pubicalyx and H wayetii

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 This the lei flower of Hawaii


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 '11 - 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! AND, to top it off - we lost the big plant of H schneei, last year.

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
