Growing it

Propagation: division, seed
When to plant: spring, summer
Overwintering: Move containers indoors before the first frost. If planted in the ground in cold climates, lift the rhizomes and store them in a cool, frost-free place.
In containers: It is excellent for containers, but ensure the pot has no drainage holes or sits in a deep saucer of water.

Division

1. Carefully remove the plant from its pot.
2. Use a sharp knife to cut the root mass into smaller sections.
3. Ensure each section has healthy stems and roots.
4. Replant into moist, rich soil.

Group moisture-loving plants together to create a humid microclimate that reduces water stress.

Good to know

Papyrus can grow directly in water up to 30 centimeters deep.
The plant is technically a sedge, not a grass.
It was once so abundant in the Nile Delta that it was considered a weed.
The umbels look like feathery fireworks exploding at the top of the stems.
