  • Other common names Peruvian lily

  • Synonyms Alstroemeria aurantiaca
    Alstroemeria aurea orange

  • Family Alstroemeriaceae

  • Genus Alstroemeria are fleshy rooted herbaceous perennials forming spreading clumps of erect stems bearing narrowly lance-shaped leaves, with umbels of showy funnel-shaped flowers in summer

  • Details A. aurea is one of the hardiest of the genus, with yellow or orange-yellow flowers, patterned with brown dots, in June-July . It spreads vigorously, but the roots are brittle so care is needed when transplanting. Many selections and hybrids are now available in a large range of colours. Pulling, rather than cutting, stems for cut flowers will encourage repeat flowering
