I have a few spots in/near my city where I can see rare orchids at a certain time of year. Two of them on a hill bordering the city I discovered entirely on my own, Spiranthes spiralis on a small old field remnant, and Orchis pallens on a stony hillside near the top. Some research on GBIF and in old papers did not seem to list the species occurring there. I emailed the local state botanist who also was unaware of them growing there and after checking their secret database said it even extends the known range slightly northward for one - but he seemed rather uninterested otherwise (the entire hill is private property and there’s no chance of protecting anything, so it’s actually kinda sad still finding rare species there).
A third orchid spot I’m particularly fond of is in a dark forest near the top of the neighbor hill to the above where I found my first ever Epipogium aphyllum, and in full bloom, in 2023 - after finding a vague location description (“near the bear cave”) in a 100-year old botany paper describing new plant finds in Salzburg at the time.
I trekked up there several times this year as well but there was nothing - and some orchid enthusiast I met elsewhere told me he had heard about that spot, but the flowers only come up every 5-10 years and I was really lucky to find one in 2023.
