Helianthus Water Drop Poem: “Light Reaching Toward the Sky”

by Aqua

The helianthus is
a flower that seems to hold a drop of the sun itself.
Its orange petals
glow softly as they catch the light.

Tall and slender,
when swayed by the wind, it looks as if it’s reaching out toward the sky.
“It’s not so bad to look up,”
it seems to say, offering a gentle word of encouragement.
