Flowering plants of Hedera helix L. in the Grunwald district of the city of Poznań

Abstract

In the period from September 2008 to July 2009 in the Grunwald district in the city of Poznań, Poland, a total of 609 localities of flowering English ivy were recorded, for which 769 plants were described. These plants were found in different localities, most of them euhemerobic. The biggest number of flowering specimens was recorded in home gardens. Support for climbing plants was mainly provided by trees and shrubs, including fruit trees – pear and apple trees. Among the other tree species, the biggest group comprises Scots pine, common birch, European larch and common locust. Other types of supports included fences, buildings and elements of small architecture. A very high number of specimens in the generative stage in the Grunwald district indicates considerable popularity and at the same time very good adaptation of ivy not only to the climatic conditions of the city of Poznań, but also to anthropogenic changes in the habitat.
