A Liberty Co rubricorpora with a near-completely-BLACK throat — three sibling black-throated plants in Mike's tray. Environmental cause ruled out by neighbors showing normal red throats. 9 Mike photos (2018-2025).
Standout traits
- Almost completely BLACK throat — distinctive trait among rubricorporas
- 3 sibling black-throated plants in Mike's tray; environmental cause ruled out by neighboring plants showing normal red throats
- Slow to color up after transplanting (2 years post-division to recover full color expression)
- Population also includes a thin-necked sibling clone (Mike, 2023-07-20)
Cultivation
- Slow to recover color after division — ~2 years after Mike's transplant before full color returned.
- Standard rubricorpora care.

Naming
Mike's descriptive 'black throat' label — references the near-completely-black throat coloration. Three black-throated siblings exist in Mike's tray; he believes they're a genetic group (other plants in the same tray show normal red throats, ruling out environmental cause).
