When I visited Leucojum vernum in flower in the wild, it was growing in a very wet area, I believe on the flood plain of a stream. Melting snow added to the moisture. I had a hard time finding solid ground to stand on.It was the same sort of habitat that our local Erythronium revolutum grows in, so I imagine it never dries out. I understood then why it had never survived longer than its first flowering at my house. I plan to try again, planting the bulbs in a part of the garden where I water all summer.
