Flowers That Need Lots of Water
Flowers have particular needs and wants. Not all flowers survive a drought and need to have a soil that is moist to wet all the time, with some having the ability to grow in standing water. Flowers that need water solve the problem of a low-lying area in the garden where the water settles after a storm. Plant water-loving flowers near ponds and streams and places within the reach of the hose or irrigation system.
Goat's beard (Aruncus dioicus) is a member of the rose family and is hardy in USDA zones 4 to 8. The plant is native to the west and central regions of Europe as well as southern Russia and the Caucasus. Plant goat’s beard in full sun or partial shade and a soil that is moist to wet and well-drained without any standing water. The plant grows from 4 to 6 feet tall with a spread of 2 to 4 feet. Cream-colored flowers grow in long clusters with male and female blossoms on different plants. The flowers bloom in April and May along with dark-green, compound leaves.
Jack-in-the-pulpit (Arisaema triphyllum) belongs to the lily family, growing from 1 to 2 feet tall and about 18 inches wide. Tiny green to purple flowers grow in long clusters and bloom in April and May. Female flowers do not appear until the plant is mature, growing at the bottom of the cluster and are followed by clusters of red berries. Each plant produces two compound leaves measuring from 1 to 1 1/2 feet long, growing over the top of the flower. Jack-in-the-pulpit is native to the eastern United States and is hardy in USDA zones 4 to 9. Plant in medium to wet soil and partial or full shade. The plant does not do well in heavy, wet, clay soil.
