Propagation and Arum Lily Planting

The simplest and quickest solution for growing arum lily is to multiply it by division of rhizomes or plant bulbs. You can also grow it from seeds: Sow seeds on the surface of a hot and humid soil in spring or summer. Keep them in a bright location. Germination takes place between 1 and 3 months. The ideal germination and growing temperature is around 60 F (15 C).

*In tropics and warmer zones: USDA Zones 8 – 11 or other parts of the world, grow it anytime, when temperature stables around 60 F.

In the garden

Plant arum in spring, in a humus rich soil, 15 cm deep with a spacing of 30-40 cm between each plant. Water generously during the growing season without leaving the soil dry between two watering spells.

In the Pot

For cooler climate, growing arum lily in pot is best. This way you can move it inside in winter. In a small garden, balcony or terrace, pot grown arum lily looks beautiful. Choose loam based potting mix for optimum growth.


Planting in a Pot

Allow Arum lily fruits containing the seeds to turn brown and dry before picking them. The fruits will develop in the fall after the plant has bloomed and the flowers are spent. Wearing gloves, open the Arum lily seedpods and remove the seeds.

  • Arum lilies (Zantedeschia) belong in the family Araceae and include Calla lilies and Lily of the Nile.
  • Allow Arum lily fruits containing the seeds to turn brown and dry before picking them.

Fill a small container with warm water and place the Arum lily seeds into it. Allow the seeds to soak overnight before planting in soil.

Fill a planting container with a well-draining potting mix that is rich in organic material. Be sure the container has holes in the bottom for drainage. Place the seeds on top of the soil and sprinkle with a light covering of potting mix. Water the container well.

Situate the container outdoors in an unheated greenhouse. Keep the potting mix moist, but not soggy, until the seeds have germinated--about four to 12 weeks. Transplant seedlings into your garden in spring after the threat of frost has passed.

Arum lily bulbs will be true to the parent’s coloration, but Arum lily seeds will not always produce the same colored flowers as the parent plant.

Fertilize Arum lilies regularly with a water-soluble fertilizer.

Arum lilies will work well in butterfly gardens as they attract not only butterflies but also bees and birds.
