What is a cultivar?
From Article 2.3 of the ICNCP:
“A cultivar, as a taxon, is an assemblage of plants that (a) has been selected for a particular character or combination of characters, and (b) remains distinct, uniform, and stable in those characters when propagated by appropriate means…(but see Art.9.1 Note 1″
Article 9.1, Note 1:
“No assemblage of plants can be regarded as a cultivar or Group until its category, name, and circumscription have been published…”
“Only plants which maintain the characteristics that define a particular cultivar may be included in that cultivar (Article 2.5).
Do you have a cultivar? In the genus Hoya, a cultivar usually originates as a sport (branch mutation), seedling, or hybrid. It is okay to not be immediately sure if you have something unique. It should aways be grown for awhile first while stability is determined. There should also be a number of individuals before it is released to the market.
