How to Propagate Sempervivum ‘Neptune’

Sempervivum ‘Neptune’ can be propagated from offsets, or “chicks.” It does not grow true to seed.

Offsets

‘Neptune’ will produce small rosette offsets. Cut the offsets off from the main stem with a sharp, sterile knife or scissors. Allow the offsets to dry for one to two days before laying on well-draining soil.

Flowering Information

‘Neptune’ is monocarpic, meaning that it blooms once and then dies. It can take several years before ‘Neptune’ flowers. Flowering usually occurs in the late summer or fall.

Flowers attract bees and butterflies.
