- First described
- 2012
- Type
- multi clone locality recovered from seed backup
Origin
Two genetically distinct clones from Oakland County, Michigan ssp. purpurea wild population. Mike held both individuals as of 2012; specific wild site / collector not stated.
A loss-and-recovery sequence: both mother plants were subsequently lost (date unspecified). Mike had crossed the two clones before the loss and stored backup seed; ~8 years later, two seeds germinated (2022). Those two F1 plants are now the recovery stock.
History
- Pre-2012: Mike acquires both clones.
- 2012-09-10 (post #1): first forum documentation, with observation that ssp. purpurea genetic diversity is narrower than e.g. leucophylla per recent studies.
- ~2014 [VERIFY]: cross-and-store seed backup made. (Mike's 2022 post says 8 years since the cross.)
- Subsequent (date unspecified): both mother plants die.
- 2022-08: 2 of the backup seeds germinate; recovery underway.
Standout traits
- Upright growth habit — atypical for ssp. purpurea.
- Two distinct clones in original collection — visible phenotypic variation in 2012 photos.
Cultivation notes
[MISSING] for the focal clones. The history demonstrates the value of seed backup even for "non-rare" species — single-clone storage cost Mike both mothers, but the cross-store strategy saved the genes.
Photos
8 Mike-Wang photos: 5 from 2012 documenting the two original clones, 3 from 2022 showing the F1 recovery seedlings.
Standout traits
- More 'upright' growth habit than typical purpurea ssp. purpurea (Mike, post #1, 2012) — subtle but reproducible
- Two distinct clones in the original collection — phenotypic variation visible across pictured plants
Cultivation
[MISSING] — no specific cultivation advice in the thread; standard ssp. purpurea care implied.
Conservation note: Mike's loss-then-recovery sequence is a practical example of why seed-backup matters even for non-endangered species. The cross-then-store strategy preserved the lineage when both mother plants died; a single-clone strategy would have lost the line.
