Plants That Need a Lot of Water

Updated February 21, 2017

All living things need water, and plants require more water than animals. By weight, animals are 75-percent water while plants are 90-percent water. Plants use water to transform the light energy from the sun into nutrients. The amount of water plants need is dependent on the age of the plant, the amount of light it gets and the type of plant.

Autumn Fern

Autumn fern (Dryopteris erythrosora) is also known as Japanese shield fern. Autumn fern grows best in shade and moist, water-retentive soil. Autumn fern has bronze-red evergreen foliage that changes to a green colour during fall. The fern reaches a mature height of 1 ½ to 2 ½ feet, and spreads to about 2 to 3 feet. Autumn fern has sturdy fronds that are often used in flower arrangements. Plant the fern during spring in the shade. Autumn fern requires regular watering.

Elephant Ear

Elephant ear (Alocasia spp.) is a tropical plant that is grown for its foliage. Like the majority of the tropical plants, elephant ear thrives in wet and moisture-retentive soil. The plants do not perform well in heat or direct sun, and the leaves tend to bleach out. The lightly scalloped leaves are very large and can grow up to 2 feet long on thick stems. The plants reach a mature height of 2 to 12 feet and spread to 8 feet. Though elephant ear is a water-loving plant, it does not like its roots to sit in water. The best time to plant elephant ear is in late spring and early fall.

Confederate Rose Hibiscus

Confederate rose hibiscus (Hibiscus spp.) is also known as mallow. The water-loving plants grow well in boggy soils, and are a native of swampy areas. The plant is a large, perennial flowering shrub that produces double flowers between spring and fall. The flowers bloom in white and age to pink and dark pink. Confederate rose hibiscus reaches a mature height of 5 to 10 feet and spreads to 3 feet. The plants do not require regular pruning. The recommended planting time for confederate rose hibiscus is in early spring or fall in areas that receive full sun. Use a ½-inch organic mulch after planting to help retain moisture in the soil.
