  • Garden care:
    These plants are potted up (using a suitable aquatic compost) into aquatic pots. These pots are made of a fine mesh, which allows water to circulate through the compost, providing the plants with both oxygen and nutrients. If you are using them as a aquatic plant, they can be planted into neutral to acidic soil (for best results) up to a water covering of 25cm (10") deep. To enhance flowering divide congested clumps every three to five years.
    • Humans/Pets: Harmful if eaten
