Frequently Asked Questions
Can this plant be overwatered?
Can this plant be overwatered?
It's described as one you can't overwater, which makes it a forgiving choice for anyone who tends to water houseplants too generously.
Does it need repotting when it arrives?
Does it need repotting when it arrives?
No, the 1 litre size is supplied in a mesh basket and doesn't need repotting straight away, though moving it to a larger basket before planting can help if you want extra root room.
How deep should I plant it in my pond?
How deep should I plant it in my pond?
Start it off at around half the plant's recommended planting depth so it has time to establish, then lower it further once it has settled in.
Can I keep it indoors instead of in a pond?
Can I keep it indoors instead of in a pond?
Yes, it also works as an indoor or conservatory plant, as long as it's kept away from frost, given plenty of light and the compost is kept moist.
What happens if it grows very tall?
What happens if it grows very tall?
Once it passes roughly 60cm in height, it benefits from a larger mesh basket or being planted into gravel, which helps stop it toppling over in windy spots.
Cyperus alternifolius suits pond margins, large containers and conservatories, and it's a good match for anyone who tends to overwater houseplants, since constant moisture doesn't harm it. It helps take the pressure off getting watering exactly right. You get one plant supplied in a 1 litre pot, already established in its mesh basket and ready to plant.
Cyperus alternifolius is a marginal pond plant and houseplant grown for its upright stems topped with umbrella-like heads of fine, grass-like spikelets, and its main point of difference is that it thrives on being kept permanently wet rather than struggling with it. That makes it well suited to pond margins, large containers and conservatories, and it helps take the guesswork out of watering for anyone who tends to overdo it with houseplants.
You receive one plant in a 1 litre pot, already growing in its mesh basket. There's no need to remove or replace that basket, whether you're moving it straight into a pond margin or transferring it to a larger container first.
What sets it apart is that conditions most houseplants can't handle for long, being kept consistently damp, suit this one just fine. It also brings steady, reliable growth and seasonal flower umbels through the summer, giving it interest beyond its upright foliage.
