Arthur, you inspired me to look for the recommended minimum temp for the jenkinsii. I never heard the plant was difficult, so I waltzed on ahead. Plus a year ago, I thought this plant had died from weeks of severe underwatering in low humidity. Richard advised me on its care via his Backbulb forum. Thanks again, Richard! Well, it was the minimum tempS, everything from * 73F in Puerto Rico, average winter low to * the 50s F at least, with the plants being quite tolerant of 40s F and brief periods at or near freezing, Marble Branch Farms, S Carolina The data: - Moderately warm http://www.orchidwubben.com/ - Intermediate-Warm, orchids.com - Norman's - Oct. - March, average lows 75 - 71F, Puerto Rico (successful individual grower) - average winter low in my area is mid to upper 60's, Miami, FL (successful individual grower) - move it in Nov. to a cooler position where it goes down to about 14c (57F) at night (successful individual greenhouse grower) - cool dry rest from Nov - Feb.; MIN TEMPERATURE 13C/55F, Orchidspecies.co.uk - night time temperatures near 50, Seagrove Orchids, NC - winter temp minimum of 6C/43F, Taipei (successful individual grower) - night temperatures need to fall into the 50's at least, with the plants being quite tolerant of 40's and even brief periods at or near freezing, Marble Branch Farms, SC And "Care of Dendrobiums orchids kept in the heat all year without resting period," Minimum night time temperature of 61F to 68F (16c to 20c), Orchibloom.com Recommended resting periods ranged from October to December, lasting till February or March. Once again, orchids tolerate our inconsistencies.

richardol- Size is exactly what I am shopping for right now. All my orchids are in a room shut off from my cats. 2 windows, about east and south (my house sits at an angle on my lot, so thats not exact) I live in NE Oklahoma, so the summers have rather strong sun. Shelves in front of the windows. I have humiditry trays for most of my plants. I have 7 phals, a dendrobium that was unmarked, a den. jenkinsii, a catt, a brassocattelya, and a den. wenzelii (which is brand new). All of the plants seem just as happy as can be! Not sure what conditions you would consider that, cold/warm dry/humid whatever. The room stays roughly the same temp as the rest of the house. In the winter the window get relatively cold though, being single pane. I have always wanted a Paph, preferably a small one, since I am running out of space in my plant/work room. :S I tend to be drawn to red, purple, rust, orange, striped etc blooms when I am shopping. So far orchids marked 'easy' and 'intermediate' in the difficulty scale have all worked well for me. Currently seriously thinking about a Masdevallia I found on J & L Orchids.

Dendrobium aggrgatum is no more. It's been rename Dend lindleyi. As I said I have 4 Dend aggregatum, 3 I have renamed Dend lindleyi and one is now Dend jensinkii. Usually one, maybe 2 will bloom in the spring but this is a bumper crop year, 3 will have bloomed. Dend jensinkii is now open and lindleyi has a spike. Another lindleyi bloomed some time ago. This will give a perfect opportunity to compare the two. Here is jensinkii hanging from a coconut which houses lindleyi. The pbulbs of one are 3 to 4 times the size of the other. The spike of lindseyi will be 4 times longer than jensinkii. I think they will be open at the same time. I think lindseyi will be more yellow while the jensinkii will be more orange. Nick

Cool and dry during winter. Almost zero water for two or three months should do the trick. It might just take time. This one didn't bloom for many years and only started a few years ago. I didn't change much to induce it to bloom. Threaten to throw it away and it might bloom.
