Spider Plant (Chlorophytum comosum)

Spider plant has survived in homes since the Victorian era, producing baby spiderettes on long arching stems for free propagation—a feat outperforming pothos in plantlet volume. It tolerates low light, inconsistent watering, and root-bound pots, with NASA ranking it among the top air-purifying plants for removing CO2 at 95% efficacy over a day. Its grass-like leaves can grow up to 2 feet long, thriving for decades from a single cutting. Over 70% of households in mild climates own one, and it's cheaper than the typical rival at under $10 for a starter pot, rebounding quickly from missed waterings.
