The brooklime is a very common semi-aquatic plant that is found in abundance in most of the places, including the United Kingdom, Europe, Asia and North Africa. Normally, the plant grows in trenches, close to fresh water ponds and along the banks of streams. The plant grows and thrives easily and well in more or less luxuriant earth, but flourishes in shallow streams or water having a depth of approximately 15 cm. This variety of herb has a preference for breezy summer climes and does not require too much of sunlight. The brooklime plant attracts plenty of bees owing to its cluster of blooms and is sometimes referred to as an 'excellent bee plant'. Brooklime is normally propagated through its seeds. The seeds are generally sown in a cold enclosure during the autumn and when the seeds germinate and the seedlings have grown up sufficiently, each of them is carefully pricked and placed in separate pots. Later, during the summer, the plants are placed outside in sunlight. In the event of a person having plenty of brooklime seeds, he may directly sow them in plants' original locations during the spring or the autumn. The plant's division may be done any time during its growing period. Growing the plant from the stem cuttings is quite simple as even a small part of this plant will develop roots when placed in water.
Brooklime contains tannin, some sulphur, a special bitter principle, and a pungent volatile oil.
