Himalayan Balsam (Impatiens glandulifera), fam. Balsaminaceae.
Occurs very rarely, in quite strange places, such as the littered sites in the outskirts of residential areas. Mighty plants (up to 1-2 m height) with large, bright flowers (which appear in July) look wonderful for such places. The plant gets rid of an excess of water by means of glands along the leaf borders, looking like sticky droplets.
Himalayan Balsam appeared in our land no more than a hundred years ago, and it really originates from the Himalayas. In the future we can expect plentiful spreading of this aggressive weed, which propagates by self-seeding. At the same time, the unusual beauty makes it possible to cultivate as an ornamental plant.
