Question 1

True or false: Sempervivum is actually a type of cactus native to the Americas.

Accepted Answer

False. Despite looking cactus-like, Sempervivum is a succulent in the Crassulaceae family, native to Europe, not the Americas.

Question 2

True or false: Sempervivum requires frequent watering every few days to stay healthy.

Accepted Answer

False. As succulents, they store water in leaves and prefer infrequent, deep watering; overwatering causes rot quickly.

Question 3

True or false: Sempervivum leaves can change color based on light and temperature stress.

Accepted Answer

True. Stress from intense sun or cold triggers anthocyanin pigments, turning leaves red, purple, or bronze—a natural adaptation.

Question 4

True or false: All Sempervivum species produce identical, pink flowers.

Accepted Answer

False. Flower colors vary by species—from pink to yellow, red, or white—and bloom at different times, though all are star-shaped.

Question 5

True or false: Sempervivum flowers only once, then the entire rosette dies.

Accepted Answer

True. Each rosette is monocarpic—blooming after years of growth—but the plant lives on via offsets (chicks) around the mother.

Question 6

True or false: Sempervivum grows best in rich, high-nitrogen potting soil indoors.

Accepted Answer

False. They thrive in poor, gritty, well-draining soil; rich soil leads to leggy growth and rot, and they need outdoor sunlight.

Question 7

True or false: Sempervivum can survive being frozen solid and still bounce back in spring.

Accepted Answer

True. These alpine succulents have antifreeze-like cell fluids, allowing them to endure extreme cold down to -30°F without damage.

Question 8

True or false: Sempervivum was historically used in Europe to ward off lightning strikes.

Accepted Answer

True. Romans and medieval Europeans planted Sempervivum on roofs, believing it protected homes from lightning and fire.
