Hibiscus moscheutos is better known as swamp mallow or rose mallow. This flower resembles the tropical hibiscus, but is an annual flower native to Europe and naturalized throughout the United States. Swamp mallow grows readily from seed and will provide blossoms all summer long. Its flowers range in color from white to pink and rose. Hibiscus moscheutos will attract bees and hummingbirds.
Choose a full-sun location that will allow plenty of room for the mature flower when the soil temperature has become quite warm. Hibiscus moscheutos can reach 7 feet in height when mature. Texas A&M University's website suggests planting when the soil reaches 70 degrees F.
Dig a trench in the soil that's 1/8 inch deep, using your small trowel. Place the rose mallow seeds in the trench, following the spacing guidelines on your packet of seeds. The seeds have an approximate success rate of 60 percent germination, so plant more rose mallow than you want to have to ensure you get enough.
Cover over the seeds with soil. Water the ground until it becomes quite moist. Monitor the ground and continue to keep the soil moist until your rose mallow germinates, typically in 15 to 30 days.
