Sedums have a high heat tolerance.

• A. High heat tolerance
• B. Low heat tolerance
• C. Water-logged tolerance
• D. Cold intolerance

Answer: (A)

Sedums are sun-loving, drought-tolerant plants whose succulent leaves store water and have a thick, waxy cuticle to minimize water loss. These adaptations come from growing in rocky, exposed environments with hot sun, so they genuinely handle high heat well. In cultivation, they thrive in full sun with well-draining soil and can suffer if roots stay soggy, which is why “water-logged tolerance” isn’t accurate. They’re also generally hardy to cold in many varieties, so “cold intolerance” isn’t a defining trait of sedums. The combination of sun exposure, water storage in leaves, and efficient water-use under drought conditions explains their high heat tolerance.
