Miltonia spectabulis
Here is why we practice with rescue orchids. Sometimes you get a nice addition to your collection. That is what happened here.

No, I didn't get the orchids in the picture, but a group of three like them, one of which was semi-alba. If these can be rescued, I will have something worthwhile.

Miltonia spectabulis is from Brazil. It is cool to hot growing and likes moderate light. It should not dry out but doesn't want to be too wet either.

All three had been badly overwatered and the roots on all of them were gone. I trimmed them mostly off. All three have new growth and one of the new growths has roots.

Number 3 has a lot of pleating. Pleating of the leaves occurs when the plant doesn't get water at a critical stage of growth. Pleating will never go away. The best that can be done is that in 3 or four years, the plant can be divided, removing that pseudobulb.

Eventually they will be mounted, but for now they will remain dismounted. By dismounted I mean bare root on a filled humidity tray getting watered every day.

A year later

The plant was potted in rock and grown in moderate light. It developed new growth on 3 leads and has bloomed.

We are going to declare this plant as rescued. The next phase will be to mount it on a big piece of cork. It will look a bit small at first, but over the next couple of years will cover quite a pit of space.
