Tips for Growing Swamp Hibiscus


The swamp hibiscus is also referred to as the Scarlet Rose Mallow around the country although people in the United States call it the Texas Star.  However, the scientific name of this plant is Hibiscus coccineus.  The flowers consist of single blooms that have five points.  Plants can bloom sporadically or flowers will bloom all at once.

The swamp hibiscus is a beautiful plant that can grow up to 12 feet tall, which is unique for flowers in the hibiscus family.  Because of the potential size, this plant needs between four and six feet space to grow.  For the best results, you want to grow the hibiscus in United States zones 6 to 11.  In addition, this plant needs full sunlight to partial shade.

The flowers of the swamp hibiscus are simply gorgeous and a dark or scarlet red.  Flowers bloom during the mid to late summer and even into the early fall months.  Foliage of the swamp hibiscus is also beautiful, consisting of dark green leaves that have a smooth texture.  The blooms of this hibiscus naturally attract various species of birds, bees, and butterflies, making it a great addition to any garden or flowerbed.

Keep in mind that the swap hibiscus likes certain soil, which would range from 5.6 to 6.0 for mild acidic, 6.1 to 6.5 for mild acidic, and 6.6 to 7.5 for neutral acidic.  For planting, you will need to purchase high quality seeds, which would be placed in the ground after the last frost has passed, usually in early spring.  Remember, at the end of the blooming season, you can collect seeds to plant more swamp hibiscus.  You will need to water the swamp hibiscus often in that it appreciates being moist.

After the swamp hibiscus plant reaches two feet tall, we recommend you cut it back so you end up with a compact plant.  Otherwise, it would quickly grow beyond what you wanted or expected.  However, if you purposely chose the swamp hibiscus for its incredible height, you would simply leave it alone and allow it to grow.

Most people love this type of hibiscus because it grows quickly and is relatively easy to grow.  Other types of hibiscus can be somewhat finicky so having a plant with beautiful red blooms that anyone can grow is a huge benefit.  Interestingly, the leaves of this plant look very similar to the marijuana plant but this plant is legal.

After enjoying the swamp hibiscus plant during the summer and early fall months, after experiencing a freeze, you need to cut the stalk back or the plant would burn and possibly die.  As long as you do this, the plant will come back and bloom every year since it is a perennial.  The swamp hibiscus makes an exceptional addition that is simply gorgeous.
