Summer Plants And Flowers Biography
Carolus Clusius planted tulips at the Imperial Botanical Gardens of Vienna in 1573 and later at the Leiden University's newly established Hortus Botanicus, where he was appointed director. There he planted some of his tulip bulbs in late 1593. As a result, 1594 is considered the official date of the tulip's first flowering in the Netherlands, despite reports of the flowers being cultivated in private gardens in Antwerp and Amsterdam two or three decades earlier. These tulips at Leiden would eventually lead to both Tulip mania and the commercial tulip industry in Holland.[13]The reproductive organs of a tulipAnother account of the origin of the tulip in Western Europe is of Lopo Vaz de Sampaio, governor of the Portuguese possessions in India. After attempting to usurp power from the rightful governor, Sampaio was forced to return to Portugal in disgrace.[clarification needed] Supposedly, he took tulip bulbs back to Portugal with him from Sri Lanka. This story does not hold up to scrutiny though because tulips do not occur in Sri Lanka and the island itself is far from the route Sampaio's ships would have likely taken.Regardless of how the flower originally arrived in Europe, its popularity soared quickly. Carolus Clusius is largely responsible for the spread of tulip bulbs in the final years of the sixteenth century. He finished writing the first major work on tulips in 1592, and he made note of the variations in colour that help make the tulip so admired. While occupying a chair as a faculty member in the school of medicine at the University of Leiden, Clusius planted both a teaching garden and private plot of his ownwith tulip bulbs. In 1596 and 1598, Clusius suffered thefts from his garden, with over a hundred bulbs stolen in a single raid.Between 1634 and 1637, the early enthusiasm for the new flowers triggered a speculative frenzy now known as the tulip mania. Tulips would become so expensive that they were treated as a form of currency. Around this time, the ceramic tulipiere was devised for the display of cut flowers stem by stem (bouquets displayed in vases were rare until the 19th century, although such vases and bouquets, usually including tulips, often appeared in Dutch still-life painting). To this day, tulips are associated with the Netherlands, and the cultivated forms of the tulip are often called "Dutch tulips." In addition to the tulip industry and tulip festivals, the Netherlands has the world's largest permanent display of tulips at Keukenhof, although the display is only open to the public seasonally.Botrytis tulipae is a major fungal disease affecting tulips, causing cell death and eventually the rotting of the plant.[15] Other pathogens include anthracnose, bacterial soft rot, blight caused by Sclerotium rolfsii, bulb nematodes, other rots including blue molds, black molds and mushy rot.[16]Variegated varieties admired during the Dutch tulipomania gained their delicately feathered patterns from an infection with the tulip breaking virus, a mosaic virus that was carried by the green peach aphid, Myzus persicae. These aphids were common in European gardens of the seventeenth century. While the virus produces fantastically colourful flowers, it also causes weakened plants prone to decline.Today the virus is almost eradicated from tulip growers' fields. Tulips that are affected by mosaic virus are called "broken tulips"; while such tulips can occasionally revert to a plain or solid colouring, they will remain infected with the virus. While some modern varieties also display multicoloured patterns, the patterns result from breeding selection for a genetic mutation. In these tulips, natural variation in the upper and lower layers of pigment in the flower are responsible for the patterns.
