Default Dendrobium pierardii

When to Norman's orchids (orchids.com) open house in April and got this. I don't want to pretend I flowered this, I bought it in bud.
My question is how cold can this orchid take? If I leave it out in winter min temps around here is 48 or so (10 c)
I bought a Den parishii last year. It is still dormant. I might have killed it cause too cool of temps.
Don't wanna do the same for this one.

Adorable flowers....did you notice the fragrance early in the morning?
You are in Los Angeles and the short term frost in your area will not kill it. Just put it near a wall for thermal heat at night.
You must stop watering December 15 and only spray it if you see that the canes shrivel and dry....wait til new buds appear then continue the regular watering and fertilizer....
My plant produced only four flowers and more keikis....I must have watered it too soon....
*winter rest must be religiously observed to produce bountiful flowers

Yep, I have this orchid for the past 5 years but I have to really perfect the winter rest to get the correct flower form. I like the way the flowers cascade in your pictures. Your plant must have the correct humidity and temperature while growing and was given proper winter rest. In my environment I either blast the buds or manage to bloom only one or two flowers; even if I have robust canes and resplendent leaves in the summer. I have yet to see something presentable to post….maybe next blooming cycle.
This is endemic to Hainan, China….the eastern Himalayas all the way down to Vietnam and Thailand. It needs medium shade and plenty of water since they have heavy cloud cover in natural habitat when the keikis appear. When the new growths mature in autumn, light should be increased all the way to a drier winter rest period to initiate blooming the following season. I use seaweed mix to the fertilizer I give it weekly.
* your grow zone is a bit similar to where these plants originated from; maybe put it in a shady part of the wall in the summer and move it to a bright shade in the winter. When I lived in LA for a couple of years my Dendrobiums lived outdoors. Even my Epidendrums were planted on the ground and lived thru the short period of frost....

Thanks bud I will grow it cool in winter.
The reason I asked is because I killed a parishii. Never woke up from winter slumber. May be I grew it too cold in winter. I know that not all deciduous Dendrobiums can withstand 45 f nights,
Den anosum comes to mind.

Prepare your window then....one week before frost comes put your orchids indoors....and when it is back in the 50s put them back outdoors....
just to have peace of mind

Andrew the name has been changed to aphyllum. Here is mine from a couple of years ago.


Den aphyllum LUR_5712 by kentucky4, on Flickr

I grow this in Catt light and the temp is never below 60. I don't have this one flagged as needing a cool winter.

In the fall the leaves will start getting dry edges and I cut off the fertilizer and start reducing the water. When almost all of the leaves have dropped I quit watering it until the buds appear in the spring. Once the new growths appear, I water daily and apply fertilizer.

Every week or two on a sunny day I give it a light misting. In its native habitat, they do get over night dew.

@Bud
Thanks for the advice. I have never seen frost for the 10 yrs I lived here in SoCal. But some nights are rather cold down to 45. But that is very cold for LA, furs, scarves, gloves everywhere. Will seem funny for a NYer lol
