Aristolochia macrophylla

Aristolochia macrophylla, also called German pipe, pipe flower or muff pipe in Dutch, is a vigorously upright, deciduous climbing plant with large heart-shaped dark green leaves that grow over each other like roof tiles, forming a dense foliage. The German pipe blooms from May to July with yellow-green to yellow-brown flowers, which, if you're imagining, look like a curved pipe neck and also work perfectly as an insect trap. Aristolochia macrophylla likes a position in partial shade or sun, but especially appreciates it if it does not stand with its feet in full sun. The plant is hardy, low maintenance, fairly sea breeze and air pollution tolerant, good disease resistant.
