Coral honeysuckle, known botanically as Lonicera japonica purpurea is also commonly known as Japanese honeysuckle. It is a flowering perennial with a climbing growth habit producing coral flowers in the summer that fade to yellow as they age. In addition to the beautiful flowers coral honeysuckle produces distinctive foliage that is purplish-green, deepening in hue in winter. It is hardy in USDA Zones 4 through 9 and thrives in a full sun or partial shade exposure. A low maintenance plant, it is commonly grown over an arbor or support structure, in containers or as a trailing ground cover.
Select a planting site for your honeysuckle that receives a full sun or partial daily shade exposure. Plant the seeds in the spring after the last frost or in early fall at least six weeks before the first hard frost.
Prepare a nutrient-rich and well tilled planting soil that is amended with well-aged manure and/or compost. Sprinkle a dose of slow-release granular fertilizer into the planting soil according to the label directions and mix into the soil evenly.
Plant the coral honeysuckle seeds in the prepared soil, covering over the seeds with an inch or less of soil. Place the seeds at intervals of roughly 4 to 6 inches apart. In cooler climates with shorter growing seasons, the seeds can be started indoors with the seedlings transplanted out into the garden soil after the last frost has passed in the spring.
Water the seed bed deeply so that it is saturated. Keep the soil evenly moist through germination, never allowing it to dry out. Maintain moist but not consistently wet soil throughout the growing season and scale back watering in the winter to accommodate natural rainfall.
