Kalmia Field in Altwarmbüchener Moor

Around 1830, the narrow-leaved bay rose (Kalmia angustifolia), native to North America, was introduced here, probably by nature lovers. However, it had been known in the area for 100 years earlier, namely in the Herrenhausen Gardens.This field is in full bloom from mid-June to the end of July, when it is a beautiful sight.

Leaves and flowers unfortunately look very dry at the moment.

Every June and July the Kalmia blooms in a clearing in the Kolshorn Moor. The poisonous plant is actually native to Canada. It was imported to Great Britain in the 18th century for ornamental gardens and greenhouses. Due to the personal union between Great Britain and the Kingdom of Hanover, which existed from 1714 to 1837, the plant also came to the Herrenhausen Gardens. In 1834, Hanoverian nature lovers are said to have planted Kalmia seeds in the Kolshorn moor to enhance the landscape. She has lived there since then. With a population in the neighboring Oldhorster Moor, this is the only occurrence of wild Kalmia in Europe.
