in Thoreau’s Journal:
The may-flower on the point of blossoming— I think I may say that it will blossom to-morrow. The blossoms of this plant are remarkably concealed beneath the leaves—perhaps for protection— It is singularly unpretending—not seeking to exhibit or display its simply beauty. It is the most delicate flower both to eye & to scent as yet— Its weather worn leaves do not adorn it. If it had fresh spring leaves it would be more famous & sought after.
