Houseleeks are monocarpic succulents, which means they die after flowering and producing seeds. The seeds that the flowers produce will grow into new rosettes and fill in the place of its parent plant. Houseleeks usually live for three years before flowering, so you have a long time to enjoy your plant before it dies.

What does a house leek flower look like?

In Sempervivum, the flowers are actinomorphic (like a star) and have more than six petals, while in Jovibarba, the flowers are campanulate (bell-shaped) and are pale green-yellow with six petals. After flowering, the plant dies, usually leaving many offsets it has produced during its life.

How often do house leeks flower?

Sempervivums are most valued for their distinctive rosettes of succulent, spirally patterned foliage, although they also bear attractive flowers from spring to summer. Each rosette is a separate plant, and is monocarpic – it flowers once and then dies, but is soon replaced by other new rosettes, called offsets.
