Peter Schneider. ABC's of Roses. 'King of Hearts'. (McGredy, 1968). Red. A perfectly proportioned rose, without any of the grossness of some of its contemporaries. it is also great fun for proto-hybridizers, providing one population of engaging seedlings after another, including many red/yellow bicolors. [Temporarily out fo commerce but easy to root from cuttings, it is worth the effort].
