To this particular genus belong about two hundred species of perennial aquatic plants, evergreen, widespread in the wetlands of the whole globe; only 10-15 species are grown as ornamental plants. They have erect, thin stems, up to 100-150 cm tall, with thin leaves, generally placed at the base of the stems; stems and leaves are dark green, sometimes variegated with yellow, as in S. zebrinus. From spring to summer at the apex of the stems they produce some arched and branched ears, consisting of small flowers of a brown color; the flowers are followed by the fruits: achenes, which when ripe are spread by the waterways.
The syrup plant should be planted in a very bright and sunny place; excessive shade causes poor plant growth, and sometimes the absence of inflorescences. They don't fear the cold. For optimal cultivation, temperatures must be between 16 and 24 ° C. To ensure that the plant develops and grows throughout the year, place it in a place with a temperature of not less than 13 ° C. In this way it will not go into vegetative rest and this will allow the continuous growth of our syrup. When the temperature is below 7 °, it is preferable to move it to warmer areas to avoid fatal damage to the plant.
