Did you know?
This orchid can grow twice as tall as any other ladies tresses orchid in New York. Even though it blooms in mid summer here, its species name means spring-blooming. This happened because it was originally described from the Southern United States where it blooms in the spring (Fernald 1950).

State Ranking Justification [-]
There are eight existing populations, but only three of them have been seen in recent years. All except one of them have fewer than 100 plants each. There are 26 historical records known from the late 1800s through 1975 which need to be resurveyed to see if they still exist. Nine populations are now extirpated because their habitat has been destroyed.
