Quick Answer
Certain plants like cattails, cattail relatives, and plants with deep taproots like dandelions and burdock are hidden gems for water extraction due to their high water-holding capacity.
Plants with High Water-Holding Capacity
Plants with high water-holding capacity are ideal for extracting water, particularly in arid or drought-prone areas. Cattails, for example, can absorb and store up to 95% of their weight in water. This makes them an excellent choice for water extraction. Simply cut the roots near the base, and the stored water will be released, providing a reliable source of hydration.
Plants with Deep Taproots
Plants with deep taproots like dandelions and burdock are also effective for extracting water. These plants can tap into underground aquifers, providing access to groundwater. To extract water from these plants, dig up the entire plant, making sure to capture the taproot, and then squeeze out the water from the roots.
Other Water-Retentive Plants
Other water-retentive plants like yarrow and plantain also have their uses in water extraction. Yarrow, for example, can store up to 80% of its weight in water. However, the water in yarrow and other similar plants is typically more difficult to access, requiring more manual effort to extract. Nonetheless, these plants can still be a valuable resource in survival situations where water is scarce.
