The above propagation data sourced from Claude AI

Pre-treatment: Seeds are cold stratified for an unspecified time period. They are overwintered in covered plastic containers filled with water, going through several freeze-thaw cycles until Spring.

Establishment: Seed is collected in early summer and stored in containers of water. It is important not to let the seed dry out. The plant is found in various environments including marshes, fens, bogs, and lakes.
