Problèmes courants

• Algae overgrowth — Excessive algae can shade out the plant and compete for nutrients.

La cultiver

Multiplication

division, seed, turions

Quand planter

spring

Hivernage

In cold climates, the plant will form turions that sink to the bottom of the pond. Leave these undisturbed until spring when they will naturally rise to the surface.

En pot

It is perfectly suited for containers, provided you use a pond or bowl with at least 10 liters of water.

Ensure the water remains clear of excessive algae to allow enough light for the bladder traps to function.

Bonnes associations

• Nymphaea — They share similar water requirements and provide complementary foliage textures.
• Ceratophyllum demersum — Both are free floating plants that help oxygenate the water.

Espèces similaires

• Utricularia minor — A smaller relative with similar growth habits.

Ce qu'on demande souvent

Does it need soil?

No, it is a free floating aquatic plant that absorbs nutrients directly from the water.

Will it eat my fish?

No, the traps are only large enough to capture tiny microorganisms like daphnia.

D'où vient le nom

The name Utricularia comes from the Latin word utriculus, meaning little bottle, referring to the bladder traps. The species name vulgaris simply means common.

Bon à savoir

• It is a rootless aquatic plant that floats freely in the water.
• The traps are among the fastest moving structures in the plant kingdom.
• It produces winter buds called turions that sink to the bottom to survive cold weather.
