    Default Warmth Tolerant Cym?

    I was just looking at the Houston Orchid Society's Warmth Tolerant Cymbidium list and I found a lot of hybrids with Cym. pumilum as usually the mother parent. This guy is from a very cool area, yet when crossed with a large standard can be bloomed in Houston? I don't understand a bit?!?!!

    There could be many reasons for using pumilum in the breeding,But the answer to your question proberly lies in the breeding of the pollen parent.

    i think it may have something to do with not needing the cool temp change... correct me if i am wrong, but isn't the cooler weather suppose to initiate the flowering in the general cymbidiums we see around?

    Default Alexanderi Hybrids

    The pollen parents of most of the pumilum crosses listed on the Houston page is an Alexanderi hybrid (eburnem, lowianum and lowianum, right?) That really doesn't answer the question, considering they are all cool growers as well.

    Well, cymbidium pumilum can be found in the highland of the tropics so it is quite heat tolerant.
    This is what I found:
    Cymbidium pumilum is a dwarf species, about six to twelve inches high with reddish-brown flowers. Also known as Oriental Orchid, Cymbidium pumilum was probably one of the first Cymbidium species to be cultivated and is one of the most widespread. It is found throughout Indochina, China, Japan, Borneo, New Guinea, and the Philippines at elevations ranging from 985 to 5,905 feet. This fragrant species produces flowers that vary in color from almost completely green to brilliant yellow. Although it generally flowers between January and April, it can bloom throughout the year in tropical climates.
    From its distribution, you can tell right away that if you use plants of this species from places like Indochina, Borneo, New Guinea, or the Philippinines, (tropical countries), most likely it will impart the heat tolerance into progenies.
    Cheers. Hoa.
