Zone 4–9

Marsh orchid is a specialist wildflower orchid that requires consistently moist, calcium-rich soil and partial sun to thrive. It forms a mycorrhizal relationship with specific soil fungi, making it challenging to establish outside its natural habitat. Best suited for dedicated bog gardens or specialist wildflower projects rather than general home cultivation.
