Comments: Hibiscus
coccineus or Scarlet Hibiscus or Scarlet Rose Mallow or Swamp Hibiscus or Texas Star or Hibiscus semilobatus is an eye-catching perennial with an erect growth habit. It is a native of the United States. In mid-Summer, Hibiscus coccineus produces wonderfully gorgeous, large, dinnerplate-sized, ornamental scarlet star-shaped blossoms, followed later by seed pods. Butterflies, hummingbirds and bees are magnetized by the nectar-rich blossoms of Scarlet Hibiscus while birds have a fiesta at the seeds and helping to transport them. Scarlet Rose Mallow is easily propagated from seeds or stem cuttings. It thrives best in well-drained, moist, acidic soil in a sunny to part shade environment. Swamp Hibiscus has interesting deep green foliage with five points, akin to the shape of the Lone Star of Texas, hence its common name, Texas Star. It is low maintenance and enjoys having wet feet so plant them in wet areas of the landscape, in ponds and around water fountains. Mass plant Hibiscus semilobatus for a spectacular display. Frost will kill the top part of plant to the ground but will reemerge with a stronger growth next season. Trim old stems in Spring for new growth to take place. Foot traffic finds Red Texas Star fascinating and are in awe of the dinner-size flowers. What a beauty!
