Cosmidium Cosmidium 'Brunette' with amaranthus These striking yellow-edged, mahogany flowers on their slender wiry stems belong to Cosmidium (correctly Thelosperma) 'Brunette' and behind the dark foliage of Dahlia 'David Howard' sets them off well. In front, the trailing tassels of one of the newer amaranthus, A. cruentus 'Golden Giant', drape forward from their well branched plants. Although often pillaged by birds, the amaranthus may require dead-heading to prevent a profusion of self-sown seedlings.     Annuals A-Z   ©copyright 1998 Graham Rice. All Rights Reserved.
