A few yrs. ago, I ran across a stand of about 20 C. parviflorum and was thirlled as when I had first noticed them from a distance, I thought they were daffodils. When I trekked to them, my heart almost stopped. They are growing on a moss banked natural spring which doesn't freeze in winter. I was so thrilled, I phone an orchid friend of mind and she put me on notice to NOT mention the location as there are thieves for these plants. Same with the ginseng.
With the C parviflroum, I do nothing to them as I think they are perfectly adapted to where they are and each years a couple new clumps form.
Another terrestrial orchid which intrigues me is the Spiranthes which grows in the yard where the soil is hard, clay but they therive. I've pics. of them and will try to post.
Has anyone else any cyps. growing? Leeflea.
