Hibiscus moscheutos

Swamp mallow (Hibiscus moscheutos) is a bright and cheerful addition to any garden. Its large, pink flowers appear in midsummer and can be seen all the way into autumn. It prefers wet soils, and while it can tolerate a light drought, it prefers moist conditions. It can reach up to 6 feet in height and has attractive gray-green foliage. The flowers are usually a shade of pink but can also be white, red, or lavender. It's a great choice for wetland gardens, as it can tolerate (and even thrive in) flooding conditions.

watering

Swamp mallow (Hibiscus moscheutos) should be watered deeply once a week. Water until the top few inches of soil feel moist and then allow the top layer of soil to dry before watering again. During the summer months, soil should be kept slightly damp. During the winter months, water should be reduced slightly as this plant is semi-dormant. Swamp mallow should never be left to dry out completely.

sunlight

Swamp mallow (Hibiscus moscheutos) is a plant species that prefers full or partial sun. It should receive 6 to 8 hours of direct sunlight each day for optimal growth and flowering. If planted in partial sun or light shade, swamp mallow may not flower as profusely.

pruning

Pruning swamp mallow (Hibiscus moscheutos) to maintain a vigorous, healthy habit should take place in late winter or early spring, before new growth begins. The most successful pruning method includes cutting back just the dead stems, flowers and any damaged wood. This should be done to a height of 8-12 inches. Avoid pruning any stems which are green, since this could hurt the overall health of the plant. Additionally, take care not to cut any stems that are less than 1 year old. Leaving these stems intact will encourage healthy foliage and multiple blooms throughout the growing season.
