Gemischte Staudenpflanzungen im Test

摘要

The use of soil cover perennials in public green spaces is mainly restricted to monocultures, yet mixed plantings would be more attractive in appearance. However, it is feared they would require higher maintenance. Since 1993, the Bavarian Institution for Viniculture and Horticulture has therefore been testing four plantings made up of weak to medium-growing low perennials, strongly-growing perennials, a sage and crocus monoculture, and a ground cover combination for use under young, shade-poor trees. Each month the four groups, which involved ten perennial and four spring geophyte species, are judged by twelve people consisting of trained gardeners and lay persons of both sexes. The low perennials have consistently gained the highest ratings, followed in order of preference by the strongly-growing group, the undergrowth combination and finally the monoculture. In the meantime, it has also been possible to reduce fertilisation, watering and thinning to a minimum in the mixed groups, thus proving their suitability for low-maintenance ground-cover purposes.%Mischpflanzungen aus verschiedenen Staudenarten und -sotten sind meist attraktiver und auch pflegeleichter als Beete mit nur einer Pflanzenart. Ausbreitungs- und Wuchsstärke sowie Farbe und Textur sollten dabei gut abgestimmt, die Standortanspr╚筩he berücksichtigt sein.
