These Cyperus papyrus seeds give the marsh plant of the Nile, with triangular stems topped by an umbel of very fine rays.

Papyrus grows with its feet in the water and is sown at 21 to 24 °C, with germination in 3 to 4 weeks. It is a frost-tender plant: in mainland France it spends the winter under cover.

Papyrus for sowing, frost-sensitive marginal plant, overwinter in a frost-free location

Cyperus papyrus seeds produce a papyrus with triangular stems and fine umbels, a waterside plant that needs a grow medium that is always waterlogged. They are sown at between 21 and 24 °C, with germination in 3 to 4 weeks. Hardy only in USDA zones 9 to 10, the plant must overwinter frost-free.

Papyrus has bare, smooth stems with a triangular cross-section, topped by an umbel of 50 to 150 very fine rays that falls in a ball. It is the marsh plant of Africa and Madagascar from which the ancient Egyptians made their paper, and in a pot you get the same graphic silhouette as on the banks of the Nile.

❄️ Frost-free overwintering

Cold determines how this plant is managed. Papyrus is hardy in USDA zones 9 to 10: it tolerates a few degrees below zero as long as its rhizomes stay covered, and nothing beyond that. In mainland France, you therefore grow it in a tub, outdoors from May to October, then bring it into a conservatory, a cold greenhouse or a bright room where it never freezes. Its strongest growth takes place between 20 and 30 °C, so a heated conservatory prolongs its growing season, whereas a cooler room keeps it dormant until spring.

💧 Roots in water

In its natural habitat, papyrus grows in waterlogged soil or directly in water, sometimes at a depth of 2 m. At home, it needs a grow medium that is permanently saturated: stand the pot in a deep saucer, in a reservoir tray, or on the edge of a pond where a few centimetres of water cover the soil. Ordinary watering, however generous, is not enough, and growth slows as soon as the grow medium begins to dry out. The plant tolerates water with a pH of 6 to 8.5, which covers most pond water, and the other marginal species are listed in the aquatic plants collection.

Keep the papyrus seedling warm and waterlogged

Sowing papyrus requires warmth of 21 to 24 °C, light and a grow medium that never dries out, all at once, for 3 to 4 weeks. A vented-dome germination tray brings these conditions together: its watertight base keeps a reserve of water beneath the cells, and its dome holds heat and humidity above the seeds. Place it in the warmest room of the house, near a window, and only open the vents once the seedlings have emerged.

Bring the pot indoors before the first frost

Bringing the plant in for autumn is the one job of the year that cannot be made up later. A hard frost kills the stems, and if the cold reaches the rhizomes, the whole plant is lost. Note a date in September and bring the pot in before the first forecast frosts, together with its water reserve, rather than waiting for the first damage to the foliage.

Sowing is done in spring, from March to May, on a fine grow medium, firmed down and soaked. Place the seeds on the surface and barely cover them with a veil of soil, then keep them in the light, under a transparent lid rather than under cardboard. Germination takes 3 to 4 weeks at a steady temperature, and a sowing judged after 15 days is often thrown away just when it was about to germinate. Then transplant one plant per pot, in soil that you keep soaked by standing the pot in a full saucer, and move to the large pot when the first umbels form.

🐟 At the edge of a fish pond

At the edge of a pond or in the lagoon zone of an aquaponic system, papyrus plays the part of an ornamental marginal plant. Its roots sit in the water and draw their nutrients from it during the warm season, while the stems and umbels stay above the water. It is not harvested, and the list of plants to grow in aquaponics presents the crops that do feed a bed. Its compulsory overwintering remains the constraint to build into the season calendar: the pot leaves the pond in October and returns in May.

delivery time

A packet of seeds travels as a small parcel and is combined at no extra cost with the rest of your order. The exact amount is calculated in the basket. As a plant or living organism, this product is excluded from the right of withdrawal (article L221-28, 4° of the French Consumer Code), because it deteriorates quickly.

Frequently asked questions

6 questions

6 key questions

Does papyrus survive winter outdoors in France?

No, it is a frost-tender plant. It is hardy in USDA zones 9 to 10 and only tolerates a few degrees below zero, provided its rhizomes are covered. An ordinary winter goes beyond this limit in most regions of France.

The approach that works can be summed up in one sentence: grow it in a container, outdoors from May to October, then bring it into a conservatory, an unheated greenhouse or a bright room that never freezes.

Can it be kept year-round in a conservatory?

Why haven't my seeds germinated yet?

Should you cover the seeds?

How much space should it be given at the pond edge?

What is the benefit in an aquaponics system?

It is an ornamental border plant, not a crop. It takes its nutrients from the water in which its roots sit, which makes it easy to place on a reservoir tank or a lagoon zone in the warm season. It cannot be harvested and does not replace any of the species listed on the page about plants to grow in aquaponics. Its compulsory overwintering remains the constraint to build into the season calendar.

What you need to know

Sow early, from March if you have a warm spot. With 3 to 4 weeks to germinate and then transplanting, an April sowing gives a plant that will have little to show before autumn.
Do not throw out a seedling tray after 15 days. At a steady temperature, this species takes 3 to 4 weeks to emerge, and the first shoots often appear just after that.
Keep the seedling in the light. A transparent lid retains heat without depriving the seeds of light; a piece of cardboard placed on top does exactly the opposite.
Always stand the pot in a water reservoir. A papyrus cannot be managed with a watering can: its grow medium must remain saturated, and growth stops the moment it dries out.
Make a note of the bringing-in date in your calendar as early as September. It is the one task of the year that cannot be made good, and it can hinge on a single night.
Cut the dry stems back to the base during winter dormancy and leave the green ones. The plant will reshoot from the crown in spring without needing to be cut back entirely.
