How to Propagate Brunnera?
Primary propagation methods for brunnera include division and seed sowing. Success hinges on maintaining moist, well-draining soil, partial shade exposure, and cool temperatures. Division is recommended in spring or fall, while seeds need stratification. The difficulty is generally low, with division being easier than seeds. For division, gently separate mature plant clumps, ensuring each division has roots and shoots. Plant divisions immediately at the same soil depth they originally grew. Seed sowing involves stratifying seeds for several weeks, then sowing in flats under light soil cover. Maintain consistent moisture until germination.
