Care and Propagation Information

General Care for Sempervivum ‘Neptune'

Sempervivum ‘Neptune' adds vivid color to a winter succulent garden. The leaves are velvety, turning colors based on the time of year and amount of sunlight it receives. It was hybridized by Ed Skrocki.


Sempervivum ‘Neptune' has typical watering needs for a succulent. It's best to use the “soak and dry” method, and allow the soil to dry out completely between waterings.

Where to Plant

Sempervivum ‘Neptune' is cold hard down to -20° F (-28.8° C). It does well in full to partial sun.

Plant in an area of your garden that gets 4-6 hours of sunlight a day. It is not suited for indoor growing.

How to Propagate Sempervivum ‘Neptune'

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


‘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.
