They are not full size (2/3 size of my bearded) and they aren't bulbs. They have pretty stiff leaves, not thin and don't curl. The foliage pretty much looks like the bearded except smaller and fuller, leaves not as thick.

I have a white with yellow on the falls that's a very hardy grower and I have had a dark purple with yellow but they died out a few years back. They were given to me so I have no clue !

Are they maybe spuria ? I found plenty of pictures of the blooms but not many of the foliage.

Thanks for your help !

There are shorter spurias now but mine are tall ~40+ inches.

The link below shows a large clump.

This link has photos of foliage also:
