Propagation of Kotschya prittwitzii var. prittwitzii
Kotschya prittwitzii var. prittwitzii can be propagated by seed, stem cuttings, or root division.
Propagation by seed
Seeds of Kotschya prittwitzii var. prittwitzii can be sown during the spring or fall. Before planting, the seeds should be cleaned, dried, and stored in a cool, dry place.
