The Six Horticultural Groups of Dendrobium

[quiltergal]

I have a nigrohirsute that is a cross between group IV & V. It has cruentum and formosae in it's parentage. I grow it as a group V and it's going nuts, blooms all over the place.

This is a very helpful post for those with similar Dendros. Thanks for posting this.

To which type do you think Den. Bracteosum belongs?

What kind of light does the aggeratum need?

Does anyone know what culture den.Kinganium grows in???

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.

Hello all, just found this forum and I'm glad to see it's quite active. I will be visiting often I think - Relatively new to growing orchids - mostly just phals. My sister has a Dendrobium Pegasis, which has not flowered in about 2 years, so I've taken it in and going to try and get it to flower again. As soon as I find some information out about it though... soil type, lighting, humidity, temps, etc. It desperately needs to be re-potted.

I'm assuming this is some sort of hybrid, as it's not included on the list. I can't find any information about this specific plant on the web or in my orchid books. Does anyone have any information they'd like to share?

Greatly appreciated,
Frank

I found this while doing some searching around for something else and thought it might be useful. It describes the different den. groups, and gives more examples.

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.

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.
