- Breeder
- Bob Hanrahan (lineage source); Atlanta Botanical Gardens (preservation); Mike Wang (cultivation + division)
- First described
- 2015
- Type
- AF form multi generation breeding line conservation
Bob Hanrahan's AF rosea breeding line. Original wild AF plant stolen from Hanrahan's property; he then grew 100,000+ seeds from surrounding area to recover AF segregants. Mike's plants are F2 sibling crosses; ABG preserves the lineage. Vigorous (atypical for AF roseas), eerie green color, yellow-green flower.
Standout traits
- **100,000-seedling Bob Hanrahan story** — original AF rosea found in Hanrahan's field then stolen; 100K seeds grown out for AF recovery (likely F1 from this); Mike's are F2 sibling crosses
- Vigorous + fast growing — atypical for AF roseas (most show inbreeding depression)
- Eerie green color (theplantman, post #3, 2015) — striking against typical pink-flowered roseas
- Yellow-green flower distinct from regular pink (Mike, post #14, 2020-03-21)
- ABG preservation lineage stable; Hanrahan's site population apparently destroyed (mph101, post #4, 2015)
- Inbreeding-depression risk increases with each selfed generation; Mike (post #9, 2015) outlines outcross-and-back strategy: 3-5 yrs F1, 3-5 yrs F2; total 12 years for proper improvement
Cultivation
- Outdoor Northern California.
- AF rosea cultivation caveat (Mike, post #13, 2019): more prone to rot than non-AF; don't sit in water for extended periods.
- Outcross strategy preserves location-true genetics: outcross AF parent with non-AF from same field, then back-cross or sibling-cross to recover AF expression — preserves vigor while keeping locality pure (Mike, post #9, 2015).
- Distribution: Mike → BACPS (sold out 2016); divisions periodically available. ABG holds preservation stock.

Naming
Mike (post #1, 2015): possibly Hanrahan F2 generation. May overlap with the existing Liberty Co luteola lineage but Mike treats as distinct (referencing kiwiearl's Liberty post 1743).
