Colorockz Sempervivum Collection


The Belgicactus company originated from Jef Gielis Sr.'s hobby. In the meantime his two sons, Jef Jr. & Jan have become managers. Over the years, the company has grown to cover a surface area comprising 10,000 m2 of greenhouse and 18,000 m2 of closed lava container field.

Driven by the goal of making varieties less susceptible to disease in terms of rooting and disease resistance, the Sempervivum-hybrid range, Sempervivum Colorockz©, was born.

These stunning no-nonsense ornamentals, are strong, resistant, fast to grow, easy to care for, surprisingly colourful and extremely hardy.
