Hardy Hibiscus ‘Luna Red’ | Plant Profile

Hardy Hibiscus ‘Luna Red’ (Hibiscus moscheutos) are North American swamp or bog perennials. The shape is irregularly round and shrubby, reaching to 3′ tall. Huge burgundy flowers the size of dinner plates stand out from the foliage. Up to 20 flowers can be produced per day, though they only last for a couple of days. These are some of the largest flowers that can bloom in the Pittsburgh climate, and they can be found blooming from July – September.

‘Luna Red’ prefers fertile, medium to wet soils in full sun.

‘Luna Red’ are showy and attractive additions to wet spots or low areas with excess soil moisture. They are hardy when located along streams, ponds, or lakes. They can also be grown in large garden containers.


Hardy Hibiscus 'Luna Red' Characteristics

'Luna Red' are beautiful additions to landscapes with suitable growing conditions. Humidity will not bother 'Luna Red' and regular deep watering is recommended in medium moisture soils. Though the plant can survive in part shade, full sun is needed for the best flowering and strongest stems. Good air circulation can help to prevent molds and mildews. Strong winds can cause wind damage. The plants may become leggy if the stems are not pinched back every 8 and 12 inches. Before winter sets in, cut the whole plant back to 4 inches above the ground to allow for new growth in spring. Regular deadheading of spent flowers can improve the overall appearance of the plant. Occasional fertilization can improve low fertility soils.

Leaf spot, rusts, blights, and canker may affect 'Luna Red'. If untreated, Japanese beetle infestations can cause severe damage to the foliage. Leaf scorch occurs in dry soils.
