Well... first, I'd say they probably weren't Hippeastrums, though they may have been in the Amaryllid family. It's hard telling what a catalog might call a "mini amaryllis", as many of them take license with giving plants their own names for sales purposes.

Do you recall what color the flowers were, and what time of year they bloomed?

Only thing I can think of are Zephyr Lilies... the leaves are similar to the mondo grass, but the flowers are not much like an amaryllis.

Here is a link that might be useful: Zephyr Lily

That would have been my guess, except they are described as having 4 blooms per stem, like a Hippeastrum. Rain Lilies have only one flower per stem.

Could it have been the volotta or scarborough lilly? It has red flowers that resemble hippies, not sure if its an ammy though.

It looked like the Scarborough lily. The leaves did look more narrow perhaps newer bulbs barely making it through winter barely or something.

Thanks

Rhodophiala bifida, perhaps?

Gesundheit, Jodi! LOL

Thank you, Ryan! LOL!

Rhodophiala bifida, or Oxblood Lilies, are a small red flowered Amaryllid often found growing in older Texas gardens. I believe they are native to South America. Also called Schoolhouse Lilies or Hurricane Lilies, they came to the USA by way of German settlers back in the 1800s. At one point in time, they were called "Amaryllis advena", though they are now classified as Rhodophiala bifida.
