The Six Horticultural Groups of Dendrobium

[Undergrounder]

Thanks for posting... i don't want to be picky but i've seen this list before and i've always had a small problem with the poor old forgotten aussie dendrobes. Either they get left out totally or they all get lumped in the same culture sheet, which isn't right.

You can't dump speciosum in one category because it grows native aallll along the east coast of Australia, some 3000kms from the humid, tropical, seasonal north, to the cool temperate south. The difference in culture and growth for the vars (speciosum, hillii, rex, curvicaule) is immense.

Plus where does Den kingianum and tetragonum fit in...

poor lil' things, never invited to the party.

Thanks to Ross and everybody who has contributed to this thread...there is SO much confusion about Dens

The majority of my collection is composed of Dens and although I've spoken to experts and judges regarding the different types, I'm still not sure when it comes to special care.

[Ross]

Susanne, I doubt Rebecca Northen ever meant the classification as an end-all. There's not enough specificity. Also with all the local types (like Undergrounder mentioned) the table seems, at times, an over simplification. However it does seem to explain some of the differences in care (in a general way) and might give folks a lead on how to provide winter rest, when to rest or not rest Dens, etc. It does not however address all the care issues. Thanks for putting a push-pin in this as it will keep it up where everyone can see and comment and, hopefully, add to the information contained here.

Thanks for making this a sticky Sue. It will save us having to recreate the wheel every time someone asks if their Den. needs a winter rest or not.

I found this link on dendrobiums - I thought I'd add it to this now sticky.
http://www.cloudjungle.com/epibook/Dend.html
It describes species dendrobium by their specific anatomical features ( leaf shape, type of inflorescence, etc) and cultural info.

[Ross]

Got an error for the page (Cannot display). Any idea what's going on?

[Dorothy]

No...
I have no problem bringing it up ...

Try copying and pasting it manually.

(take out the blank after http: )
I hope this works

[Ross]

Now it works. Must have been temp. down. This grouping might be even more detailed and seems to address concerns Undergrounder had. Thanks for adding this.

You are very welcome
