The Juncus effusus is a slender grass that beautifully decorates the edges of bodies of water. Traditionally, it was used to make many basketry objects. In a garden, it is both pretty and useful for wildlife.

Sowing method : Mix seeds with an equal amount of damp sand or vermiculite. Place the mixture in a sealed plastic bag. Store the bag in a refrigerator or cool storage room for 30 to 90 days. Sow seeds when there is no risk of ground frost. Sow seeds on the surface without covering after sowing. These seeds are very small and need light to germinate. Seeds can be mixed with fine sand or talcum for a uniform sowing.
