Origin
Acquired after over a decade of searching from one Michigan-area nursery — the only source Mike ever found offering this orchid for sale. Hefty acquisition price reflected the rarity. Plants arrived weak: ~3" roots, root strands no thicker than dental floss. Mike expected them to die.
Standout traits
- Practically impossible to acquire commercially.
- Mike's surviving plants recovered well after the first year and proved relatively easy to grow — once acclimated.
- 1-leaf-per-year vegetative habit (round leaf, low to ground).
- 3-year multi-year buildup pattern: 3 years in, no flowering yet, but 2 of 3 plants finally produced secondary growth points that Mike was able to separate. 3 divisions in 3 years — slow reproduction is the binding constraint on commercial supply.
Cultivation framework (Mike's protocol)
- 100% peat moss.
- Reverse-osmosis water only.
- Soil fully hydrated at all times — but never standing in water (root rot).
- Light Maxsea after spring leaf-out; stop by mid-summer.
- Treat like a CP for feeding (very low fertilizer) — Mike burned his during their weak first year.
- Part shade; NOT full sun.
Standout traits
- Mike: 'pretty much impossible to acquire' — over a decade of searching, only one source ever offered them.
- Hefty acquisition price — the rarity tax.
- Slow side-shoot production — Mike took 3 years to produce 3 divisions from his mother plants.
- 1-leaf-per-year vegetative habit — single round low-to-the-ground leaf, no further growth above ground.
- Multi-year buildup before flowering — 3 years in, no flowers; massive root system suggests next-year flowering possible.
- Plants arrived weak (~3" roots, dental-floss-thick), recovered with patient care.
Cultivation
Mike's published Platanthera psycodes protocol:
- Substrate: 100% peat moss.
- Water: reverse-osmosis only. Soil fully hydrated at all times, but pot does NOT sit in standing water (root rot risk).
- Feeding: very light Maxsea after spring leaves fully emerge. Stop feeding by mid-summer. Treat like a carnivorous plant — feed-light or you'll burn them. Mike burned his during their weak first season.
- Light: part shade. NOT full sun.
- Multi-year evaluation patience required: 3 years from arrival to first divisions; flowering still pending.
Mike's growth pattern observation: every year, just one round leaf emerges per plant, low to the ground, and that's it for the season — until the rhizome is large enough to support flowering.

Naming
Species-level designation, no cultivar name. Mike's accession is a small set of plants from a one-off acquisition.
