Frequently Asked Questions
Can this plant be grown fully submerged in water?
Can this plant be grown fully submerged in water?
No. It prefers moist soil rather than sitting in water, so it does best planted at the pond margin or in a bog garden rather than in deeper water.
Do the 1 litre and 3 litre plants need repotting before I plant them?
Do the 1 litre and 3 litre plants need repotting before I plant them?
No. Both are supplied already in a mesh aquatic basket and can be placed straight into the pond, basket and all, though a larger basket can help the 1 litre size settle further.
What exactly do I receive with the 9cm pot option?
What exactly do I receive with the 9cm pot option?
You receive a pack of three individual plants, each in its own 9cm pot. These need potting into a mesh aquatic basket before planting.
How tall does this plant get, and does that affect how I plant it?
How tall does this plant get, and does that affect how I plant it?
It can reach 60-100cm. Plants that grow past 60cm benefit from a larger mesh basket, or planting in gravel, to stop them falling over in windy conditions.
Lychnis flos-cuculi suits pond margins and bog garden borders where the soil stays damp rather than submerged, making it a good fit for the drier edges of a pond rather than open water. It offers pink, deeply fringed flowers through late spring and into summer, adding colour to the damper parts of a planting scheme. You get a live plant, supplied either in a mesh aquatic basket (1 litre or 3 litre, one plant each) or as a pack of three young plants each in their own 9cm pot. What sets it apart is its preference for moist soil over wet feet, so it covers margin positions many other marginal plants find too dry.
Lychnis flos-cuculi is a native marginal plant with branched stems, narrow lance-shaped leaves and star-shaped pink flowers split into four slender segments, grown to sit in moist soil at the pond edge rather than in open water. That preference makes it a useful choice for bog gardens and damp margins where fully aquatic marginals can struggle.
It offers colour from late spring into summer, when the fringed blooms open along the branching stems. Growth is slow, so it builds up gradually rather than spreading quickly through a bed.
You can buy it as a single plant in a 1 litre mesh aquatic basket, a single plant in a 3 litre basket, or as a pack of three young plants each supplied in a 9cm pot. The basket-grown sizes are ready to place straight into the pond, while the 9cm pot plants need potting into a mesh basket before planting.
Once established it needs little looking after. Cutting the stems back to just above the water surface once the foliage has died down in autumn keeps the plant tidy for the following season.
