(Petit 2013) Sev. Tet 7 - 7.5" 25" . The giant, massive flowers of Royal Standard are a rich, dark burgundy purple. The blooms have a lighter watermark atop a green heart. The petals and petaloids are surrounded by a crimped wire gold edge. The flowers of Royal Standard are truly huge, one of the largest doubles that I know of. Rich, saturated, and breathtaking!
