Miltonia (spectabulis x Jim MacKinney) revisited

Miltonia backbulbs - photo by Richard Lindberg

With the Miltonia spectabilis x Miltonia Jim MacKinney leads potted and tagged, I went back to the plant to finish the re-shaping. I removed all the parts of it that had grown away from the mount. The backbulbs on the mount should start new growth and get a new generation of spikes for this year. This is still a large plant.

Miltonia (spectabulis x Jim MacKinney) - Flower photo by Richard LindbergThis flower is far too nice to throw away the pieces. But since these are all rootless and leafless pseudobulbs, some as much as five years old, they are not a good bet to sprout. I cut them into single backbulb pieces and all 25 of these in community pots.

There is an inch of rock just under the pieces and there is another 1/2 inch of small bark around them to support the pseudobulbs. The bark will help keep the roots more evenly moist once the sprouting starts. As they sprout I will individually pot and tag them. They will stay in these pots until they sprout or until they turn brown.


  1. Good luck - those look like healthy backbulbs. And Miltonia spectabilis seems to grow quickly. I think you will have alot of new plants. That is a nice flower - will add Miltonia spectabilis to my list of orchid species to find.


  2. The standard spectabulis looks very similar to that picture even tho it is a hybrid. There are 2 other varieties you may see, and

  3. Wow -- really like the Miltonia spectabilis var. moreliana. It is a deeper dark-blue purple compared to the reddish purple of my Miltonia Honolulu.
    When I did a google search of Milt spectabilis saw that Francisco Miranda, Miranda Orchids had some good info. He just talked at our Orchid society last week and brought plants for sale. But no Miltonia :(
    Did get:
    Den. Maui Blush (Den. Blushing Pink x Den. Ise)
    Encyclia peraltensis
    Encyclia Gail Nakagiki (alata x cordigera)
    Laelia purpurata (flammea 'CG' x striata lisa)
    Rhyncholaelia digbyana
    Brassavola perrinii
    Cattleya (Tripp Johnson x Netrasiri Beauty)


  4. Nice group. I have wanted to try digbyana but not enough to buy one.

  5. Just curious. How did these turn out? Did they grow? Pictures update?

  6. Richard, not very well. I think they needed a finer mix and probably less light than they got. I will be doing another round of these soon because the mount is again over grown.
