What exactly is Mo Mei's poem?

Original text:

Momei (Wang Mian)

My Xiyan Lake Head Tree,

Flowers bloom and fade with ink marks.

Don't boast that the color is beautiful,

Just keep it fresh and full of Kun.

Translation:

My family painted plum trees near Xiyan Lake, with pale ink flowers. It doesn't need others to praise its beautiful color, as long as it leaves a fragrance full of dried Kun.
