Through the Dark Sod as Education — Lily-of-the-valley

Through the Dark Sod－as Education－¹
The Lily passes sure－
Feels her white foot－no trepidation－
Her faith－no fear－

Afterward－in the Meadow－⁵
Swinging her Beryl Bell－
The Mold-life－all forgotten－now－
In Ecstasy－and Dell－

(F.559/J.392)

[1] Through, Sod:: passing a valley. Education:: breeding, slow growing of a plant.
[2] Lily:: lily-of-the-valley, also called May-bell. Lily-trotter is a possible answer, but descriptions of the poem fits the flower more.
[6] Bell:: a hint on May-bell.

What is that lovely delicate plant with soft bell-like blossoms? The sweet "Lily of the Valley" or soft "May-bell" as it is often called. ─ My portfolio, a Miscellaneous Collection of Prose and Verse (1865)

the "lily-trotter" (Parra Africana), are scattered over the country ─ The Journal of the Royal Geographic Society of London (1859)
