Strawberry the winter. Additionally, in certain areas like the state of Florida, winter is the natural growing season where harvesting starts in mid-November. Kashubian strawberry ("Truskawka kaszubska" or "Kaszëbskô malëna") are the first Polish fruit to be given commercial protection under EU law. They are produced in Kartuzy, Kościerzyna and Bytów counties and in the municipalities of Przywidz, Wejherowo, Luzino, Szemud, Linia, Łęczyce and Cewice in Kashubia. Only the following varieties may be sold as "kaszëbskô malëna": Senga Sengana, Elsanta, Honeoye that have been graded as Extra or Class I. Most strawberry plants are now fed with artificial fertilizers, both before
History of manifolds and varieties History of manifolds and varieties The study of manifolds combines many important areas of mathematics: it generalizes concepts such as curves and surfaces as well as ideas from linear algebra and topology. Certain special classes of manifolds also have additional algebraic structure; they may behave like groups, for instance. In that case, they are called Lie Groups. Alternatively, they may be described by polynomial equations, in which case they are called algebraic varieties, and if they additionally carry a group structure, they are called algebraic groups. The term "manifold" comes from German "Mannigfaltigkeit," by Riemann. In English, "manifold" refers to
