Touch-Me-Not or Himalayan Orchid was introduced in Europe in 1839. Its self-seeding habit can make it a nuisance in wet mild climates. It is a fast growing annual, reaching 5′ — 6′ tall with stems 1″ in diameter at the base. The orchid-like flowers hang from the ends of the branches and are in varying shades of pink. The ripe seed pods “explode” and shoot their seeds with the least pressure.
