Some years ago, Ann Wayman and Dale Kloppenburg suggested a registry and repository for Hoya varietal names but it seems that the whole idea fell through the cracks and other priorities took over.  Also, everyone was too busy to tackle the project – and believe me that it would not be an easy one.


Dale and I both agree that to prove that a plant is a hybrid is a time consuming project for the plant must be selfed and the seedlings grown on – to show segregation.  That might take 5 years or more.  The paper work is easy compared to the nursery work.


With all of the international interest in compiling an accurate list of Hoya hybrids, the time is now ripe to establish a hybrid list and a varietal list.  Establishing a list and repository is not easily done for no recognized herbarium accepts hybrid sheets except in the case of a natural putative hybrid found in the wild.


FIRST, we must clarify a few points. Some people do not realize that hybrids and mutants are 2, very different things and the names are not interchangeable. 


Mutants are the result of a chromosome change and occurs spontaneously, whether by light rays, heat, chemicals, etc. and are shown (obvious) by changes to the growth or (hidden) by changes to the reproduction organs.   Most mutations to the reproductive parts (hidden) are lethal for the plant can not reproduce seed and the line dies out. Changes to the growth do not depend on seed production so they carry on; as leaf variegation. leaf twisting, flower color (melanism and albinism), etc.


A mutation or a series of mutations is what creates new species


Some common examples of mutantism in Hoyas are: Dimples 8, Hindu Rope, variegata in H. carnosa; Fresno Beauty, Gray Ghost, variegata in H. pubicalyx; variegation in H. australis.


Hybrids are the result of a sexual act between 2 species – the pollen (male) of one flower inseminating  another (female). This is where the pollen is placed on the stigma and the pollen tubes grow down the style and into the ovules and viable seed develops. In nature the pollination is nearly always by a pollinator (an insect or bat).  In horticulture, pollination is either accidental (by 2 plants in a collection growing side by side and pollinated by an insect) as, Pinkie (subcalva x australis), or deliberately (by hand of a human), as Kaimuki (archboldiana x macgillivrayi).


Incidentally, hybrids are listed scientifically, with an X after the genus and in front of the name; for instance, Hoya x Minibelle or Hoya x Sheppardell (carnosa x longifolia).


Patented names vs. copywrited names.  To patent a plant it must be a new, original and unusual form – that has not been offered in the trade and the patent is for the plant itself and not its name.  To copyright means to publish a name only, not the plant.


Interestingly, orchid hybrid name registry is the only horticulture group that calls all of the clones of a cross by the same name, as Cattleya Chocolate Drop (guttata x aurantiaca) and an outstand variety as 'Kodama'. All other horticultural groups select an outstanding clone and name that, as the Rose “Peace”. 


In the Hoya hybrid list shown below notice that the cross of (lauterbachii x coronaria) lists several hybrids, where Ed Gilding has named each outstanding clone by a different name, as Margaret, and Monette.


B. L. Cobia in Winter Garden Florida, has made a business out of naming varieties and copyrighting those names.
