Two or three years ago we bought this erythronium at a local nursery, Siskiyou Rare Plant Nursery, that specializes in alpine plants. For once I didn’t squirrel away the plant tags or even write things down. Their online catalog now lists no erythroniums, but maybe if I call them they’ll remember.
In the meantime, it has flourished in the shady dry place where we planted it, and is in full bloom.
Next to it, below, is E. hendersonii, the species we see most often. There are many of them on our property which we’ve encouraged through benign neglect (and seen positive results, too, which isn’t always the case with that technique).
Any suggestions as to what species this yellow beauty might be? As I mentioned in my previous post, the genus is noted for hybridization or intermediate forms, so it may be a challenge. It does not look like the yellow trout lilies of the eastern US. Erythronium americanum has orange-ish stamens and more mottled foliage (see flower picture and foliage photo, with description). Erythronium umbilicatum and Erythronium rostratum have differently shaped flowers (1, 2).
