    I'm working on an article on D jenkinsii and wanted to ask those members who live in warmer climates if you grow and bloom this species. I would like to know the temperature range this will take besides what I have here (56F minimum night and cooler). Thanks.

    Can I quote you on that? Maybe you'll want to read my article when it comes out.

    LOL!
    And it was NOT from the WOC...
    Film at 11!

    ( I would like to grow it, maybe even well....)
    So, yes, an article, please?
    I need help.
    ( On more than one species!)

    mine is outside all the time. It doesn't die but I hardly ever see it bloom.

    Thanks, Linda.

    Neyra, do you water all year round or do you stop watering in the winter? Do you know anyone in PR that does bloom it?

    Marni, I grow and bloom 2 different clones here in South Florida. I've been successful with and without a dry rest. Summertime temps mid 70's at night to mid 90's during the day. Daily water.

    Thanks, Alexis, that is good to know. Can you give me approximate night time low in winter, too. I've know others who bloom it with out a dry rest, but I could never bloom their clones without a dry rest. I don't really undestand the mechanism but am wondering if it is a difference between summer low and winter low, because it clearly isn't just water cycles.

    Marni, I'd say average winter low in my area is mid to upper 60's. It gets down to mid 40's a few nights (5-10 nights) a year. I just did a quick search for average lows in my area, and I found 47-57 degrees. That's baloney, no way is our average cold that cold!

    I used to water year round, but in winter 2007-2008 I placed the plant in a place where it doesn't get water and forgot about; Results: It bloomed. As for my growing conditions I am honestly no good with the average high lows stuff so here's this link that might help with that.http://welcome.topuertorico.org/reference/tempera.shtml As to my particular conditions, I live somewhere in that yellow range.

    Great, Neyra, the information about growing conditions is really helpful.
