Here are the exact words to this song that Mother Maybelle Carter sang. She stated that they came from her grandmother and that she had always known the song.

Wildwood Flower
As sung by Mother Maybelle Carter

Oh, I'll twine with my mingles of waving black hair,
With the roses so red and the lilies so fair;
And the myrtle so bright with the emerald dew,
The pale and the leader and eyes look like blue.

Oh, I'll dance, I will sing and my laugh shall be gay,
I will charm every heart in his crown I will sway;
When I woke from my dreaming my idols were clay,
All portions of love had all flown away.

Oh, he taught me to love him and promised to love,
And to cherish me over all others above;
How my heart is now wondering no misery can tell,
He's left me no warning nor words of farewell.

Oh, he taught me to love him and called me his flower,
That was blooming to cheer him through life's dreary hour.
Oh I long to see him and regret the dark hour,
He's gone and neglected this pale wildwood flower.

This is the one above all versions, although I am biased toward Maybelle. I consider her the "Rock" of my musical interests and influencing. A "mingle" as far as I can tell is maybe a twist or tangle in her. "Pale and the leader" is perhaps some flower whose name has become jumbled through oral tradition. Note the reference to "myrtle" in the line before. We can gather that she is going to play with her hair among the flowers, twining some within her hair. John.
