Mystery orchid growing in the mulch in my yard.?

[Lwagner]

I am new to Miami and growing orchids. I have discovered 5 orchids that have "appeared" in my mulch. 2 orchids I relocated to the Live oak tree that they were found growing under and I think they are happy. The attached pictures are of a different type that have "appeared" and I relocated the first one to the Oak tree as well. After a few weeks I noticed the leaves turned brown. I fear I may have done something terribly wrong and killed it. I removed it from the tree and put it in a pot with the mulch that I originally discovered it growing in. Fast forward a few months and today I walked outside and ........there is another one popping up. The area that these large bulb orchids are growing in is at the edge of the Live Oak canopy. The area is facing South. The first one that "appeared" I put on the North side of the tree. I am guessing that was a mistake as the mulched area keeps producing these plants in the sun. So the 2nd one I dug up and put it in a pot with the same mulch. So NOW what do I do???? And why does my mulch keep having orchids randomly appear???
The history of my property: bought the house 2 years ago and the bimbo (I am a woman so I can call her that) did NOTHING to the house for 18 yrs. I have an extremely small front yard with a LIve Oak and Mahogany. They did not have any orchids growing in them. I had a tree company bring me a load of hardwood mulch to help protect the tree roots while I had my workmen park their trucks in the front yard for a year. I finally got a permit from the city for my new front yard. The sunny area that is producing orchids is about to become stone & pavers I am sick to my stomach but really have no choice. I will hand shovel all of the mulch to another part of the yard in hopes a few more free orchids emerge. Please help me understand how to care for my new friends.

Not much to go on there, but If I were to guess, I'd say it may be a young Phaius. Probably tankervilleae.

Cheers.

This doesn't look like an orchid to me and I am pretty certain it isn't a Phaius. They have pleated leaves. This looks like some other kind of bulb to me.

Interesting - if I had seen these coming up, I would not have thought "orchid", but maybe some other flowering bulb.

But, I haven't grown Phaius before, Jim may be quite correct. Looking forward to seeing these develop - keep us posted!

My neighbor says it's an orchid. He has about 100 in his backyard but nothing like this. I have never seen a rooting system like this (up north) so I am just assuming he is correct. He is the one who told me to put it in the tree with moss & pantyhose. The roots when I dig them out are white and fleshy. The pix ois of the poor one I think I killed.

Eulophia gaminea

Lovely little orchid with a strong central spike. Common in mulch in So. Florida but indigenous to Indonesia.

Another photo of the healthy one from today with the roots slightly exposed

Yes, yes, yes, thank you sooooo much!! I googled pixs and it looks identical!!! Oh joy, now I can find out how to care for them!!!

Agree with an eulophia of some sort. I've got wild eulophia speciosa on the farm and they have a lot in common with yours. Not the same, but certainly some similarities.
