Sobralia rodgersiana

[Darold Petty]

I recently acquired a large specimen and plan to install it in a very prominent location in my garden.   The orchid is potted in sphagnum moss, in a 12x10 inch pot, with 15 canes about 74 inches tall.   I plan to install it above ground, with the bottom of the pot removed and with irrigation once per week.   After digging a hole below the pot location what sort of mixture should I use for the re-filled hole and the pot sleeve ?  The 100% moss seems wrong,  and I wish to have a mix more water retentive,  and also more "transitional" to the adjacent soil.  Thanks for any comments !

Hi Darold, long time, no talk! 

I know nothing about them personally but just happened to read a good article recently  https://www.exoticaesoterica.com/magazine/orchid-addiction-how-to-stay-sobr-alia

Hopefully some good info, he seems a serious grower.

Cheers Jonathan

Thanks Jonathan,  great article even though it has increased my lust for these plants !

   I purchased my orchid directly from Bruce Rodgers.

Darold, reading the article, it sounds like Bruce Rodgers knows what the appropriate media is for his namesake orchid.  You might still want to contact him and ask what he would do if putting in the ground though.  Before reading the article, I thought about the media that all my potted Sobralias are in.  It is more a mix of orchid bark, pumice and perlite and very well draining.  I snapped some photos so you have a visual of what the mixes are.  They are all pretty similar across the different species I'm growing (Sobralia macanthra, xantholuca, sanderae and rupicola.)  Keep us posted on how this performs for you.  Mine take quite a bit of sun on the coast so I'm sure yours will handle a great deal of sun as well in your climate.

Any blooms on it this year Darold?  Except for this one, mine are pretty much done blooming for this summer.

I don't know how to recognize the potential bloom.  I assume that it is terminal on each stem ?  My pot has various stems that previously flowered, and 3 or 4 stems now in the growth phase.  Certainly, I will post an image when I get a flower !

Your assumption is correct.  Here are examples of the flower formation.

Sobralia flowers are terminal and each stem will only bloom for one season(several flowers one after another). Those previously-bloomed stems should be pruned off since they will compete with new stems.

For a mix that retains moisture but transitions well to your garden soil, try combining equal parts of sphagnum moss, pine bark, and perlite. This blend will keep the roots well-drained yet moist.

So when does this hybrid normally bloom for you as guidance from Darold on what to expect.   Is yours in bloom now or did it already complete its flowers for this summer?

I fell in love with Sobralias in Guatemala this summer. Amazing flowers, and the plants themselves are very pretty.

My Sobralia rogersiana seems to have just finished blooming for this year with about ten flowers altogether. At most only two flowers were open at the same time. I also have an older and larger Sobralia macrantha that had close to 20 flowers at its peak bloom time in the beginning of July. Hopefully S. rogersiana will get to that level one day.

Here is my first flower !  It is about 8 inches wide by 9 inches tall !  ( 20 cm x 22.5cm)

Congratulations Darold.   It is a large beautiful flower.  You might find yourself hooked on this genus.

My bad, there is no "d"  in Bruce Rogers !
