Sempervivum is a genus of about 40 species of flowering plants that are commonly known as Houseleeks or Hen and Chicks. The Latin word 'Sempervivum' means 'forever alive'. They are succulent perennials forming mats of beautiful compact rosettes. They offset readily and are perfect as a groundcover. Sempervivum plants are easy to grow succulents because they can thrive in both cold or hot temperatures with either low or strong level of light. Sempervivum plants are a best option when you’re looking for colorful, cold-hardy succulents. They even change colors at different times of the year.
