La floriculture, ou la culture des fleurs, est une branche de l'agriculture. Elle produit par le jardinage ou la culture industrielle des fleurs coupées, des plantes fleuries en pots ou jardinières, des graines, et propagules (bulbes, tubercules, rhizomes, etc.) Ce peut être un loisir ou une activité professionnelle. Les cultures peuvent se faire en pleine terre ou en pots, dans des jardins à l'air libre ou en serres. Elle alimente un commerce international, utilisant de plus en plus le transport aérien, qui augmente beaucoup l'empreinte écologique de la floriculture commerciale. L'utilisation intensive de produits phytosanitaires, en serre ou dans certaines cultures extérieures (tulipes aux Pays-Bas) est aussi source de controverse pour la santé des floriculteurs professionnels, voire de certains consommateurs.
Holland is a region and former province in the western part of the Netherlands. The term Holland is also frequently used as a pars pro toto to refer to the whole of the Netherlands. This usage is generally accepted, but disliked by part of the Dutch population, especially in the other parts of the Netherlands.
From the 10th to the 16th century, Holland proper was a unified political region within the Holy Roman Empire, a county ruled by the Counts of Holland. By the 17th century, Holland had risen to become a maritime and economic power, dominating the other provinces of the newly independent Dutch Republic.
Today, the former County of Holland consists of the two Dutch provinces of North Holland and South Holland, which together include the Netherlands' three largest cities: the capital city of Amsterdam; the seat of government of The Hague; and Rotterdam, home of Europe's largest port.
