Mom's Outdoor Orchid

[Supergome]

Hi all, new here and have an orchid I'd love getting some help on identifying, even just a genus.

This is an orchid that was given to my mother as a potted plant gift years ago. She's had amazing success in propagating it and now has several huge clumps, all of which bloom profusely every year.

It does fine here in Charleston, SC, in a sheltered, southeast-facing nook that's in effect a bit warmer than our zone 9b, probably just occasionally flirting with frost in that spot.

I don't think I see any pseudobulbs or canes, but my knowledge of anatomy is very limited. I realize these aren't great photos, so if a shot of a specific feature would help, please let me know!
