A rose at bay

Willowherb sets its face windward.
Cornered colonizer of the wasteland
Drills seed into dust. Dry, virgin dust
An aftermath of fire fringing forest and fen.
Missiles misted London in carmine rain
And railways forged rosy wildflower borders
Like trails of dragon breath.

Rosebay Willowherb is London’s official flower –  known as Fireweed & Bombweed for obvious reasons
