Jade Plant (Crassula ovata)

Jade plants survive decades of neglect, often outliving their owners by storing water in thick leaves like reservoirs. This drought-tolerant succulent only needs watering every two to four weeks when kept in bright indirect light, and it transforms over years into a miniature tree reaching over 3 feet tall. Compared to peperomia at #7, jade retains water 50% more efficiently in its fleshy leaves, making it harder to kill through under-watering. Its woody trunk and glossy foliage earn it the nickname "money tree" in feng shui, where it symbolizes prosperity—one Japanese specimen reportedly lived 100 years. Thriving on less frequent care than typical houseplants, it demands only occasional pruning and well-draining soil to avoid root rot.
