Vertical Grass Art.
Farewell, horizontal!
British artists Heather Ackroyd and Dan Harvey are creating transient, green masterpieces, by making grass grow on vertical surfaces. They've been doing it since 1990, and this site shows a few examples of their work.
First they seeded the wall of a rustic cabin on a hilltop medieval village in Northern Italy: The Other Side project. After figuring out how to grow grass vertically up the walls of a room, then moved on the walls of a cathedral - their next project was Dilston Grove church in London.
