How to Grow

Cultivation

Grow in fertile, moist but well-drained soils in full sun ideally. Young plants are best left undisturbed to form clumps; mulch for the first two winters. See also Alstroemeria cultivation

  • City and courtyard gardens
  • Cottage and informal garden
  • Patio and container plants
