Pictures & descriptions of late perennials

Encyclopedia of 1250 late flowering perennials (concentrates on plants hardy to -5C). Text give brief description of habit (height, flower colour and flowering time, shape of leaves etc), size, hardiness and soil requirements. Each description accompanied with medium to large photos. Very useful handbook if you get visual inspiration rather than from the written word. Plants are arranged in order of flowering time rather than as standard A-Z which can be both helpful and confusing! ( )
