Hämeenkylmänkukka (Pulsatilla patens, formerly Anemone patens) is a cold flower found in the northern hemisphere and occurs mainly in Kanta-Häme in Finland. Hämeenkylmänkukka is soothed in Finland. It is a provincial plant in Kanta-Häme.
Appearance and size
Hämeenkylmänkukka is rotting and grows to a height of 10–30 cm during flowering. The stem is white-haired. The foliage grows only after flowering. Their stalks are long, usually 10 to 25 cm long. The shoulder of the leaves is 4-7 cm long and three-fingered, the leaflets are stalkless, triangular and tapered at the tip. The petioles, 2–5 cm long, grow from the base of the stem as coniferous coils. The stalks of the stem leaves are intact, broad, straight, green and white-haired. A single flower is usually located at the end of a 3-10 cm long flower stalk. The perimeter of the flower is grainy. There are six white-haired, 2.5–4 cm long perimeter leaves on the outside and they vary in color from blue to purple-blue.
In Finland, the heather flower blooms in May before the leaves of the plant break out. The abundance of flowering varies from year to year. In the fruit stage, the flower stalk stretches up to more than 30 cm in length. It develops an orchard with nuts about 3 mm long and hairy, with an eye-catching, 2 to 5 cm long potty. Hämeenkylmänkukka is a perennial and may live for tens of years. The species is poisonous. It can easily interbreed with the canopy (P. vernalis) in common areas of occurrence of the species.
Hämeenkylmänkukka is a northern plant species found in Europe, Siberia and North America. The main distribution area of the subspecies (ssp. Patens) growing in Finland extends from eastern Poland, Belarus and western Ukraine east through the central parts of Russia to western Siberia. Separate, fragmented occurrences of it are also found in Sweden, Finland, Poland, Germany, Hungary and the Baltic countries, among others. Another subspecies (ssp. Multifida) is found from central Russia through Siberia all the way to the Pacific Ocean. The distribution area continues on the North American side, where it has spread inland from Alaska to the central parts of the continent. The most important performance areas are in Janakkala, Hattula and Hämeenlinna, as well as in Kalvola, Rengo and Hauho. Elsewhere in Finland, the species is known for its observations in Pirkanmaa and a deposit found in Etelä-Savo in the 21st century. However, the number of occurrences of the species has decreased significantly in recent decades. In Finland, attempts have been made to revive the Hämeenkylmänkukka stock by planting it in new habitats.
In Finland, hämeenkylmänkukka's habitats are located on bright ridges and steep ridges. In the past, the species also occurred on grazed moraine-like field edges and field islands. In recent decades, species regeneration has become more difficult following the cessation of forest fires and forest grazing. Construction, flower collection, and transplants into gardens have also reduced the species. As the species is more common, it was sold in the spring at Hämeenlinna Market Square, among other places.
