Japanese honeysuckle (Lonicera japonica) is also sometimes called Hall's Japanese honeysuckle and gold-and-silver flower. Originally from Eastern Asia and Japan, this stout-growing plant produces an abundance of fragrant, tubular-shaped 1/2-inch long flowers that attract hummingbirds, butterflies and bees. In American, it has escaped cultivation and, in the majority of states, it's regarded as an invasive plant with weed-like characteristics. To prevent this plant from spreading and choking out other plants, plant Japanese honeysuckle in containers, such as tubs or barrels, and plan on keeping it trimmed back.
Purchase a large tub or half of a wine barrel for each Japanese honeysuckle you plan on planting. Make sure each tub or barrel has adequate drain holes. Ideally three or more drain holes ensure the best drainage possible.
Situate the tub or barrel in a location that is suitable for growing a Japanese honeysuckle. Place it in full sun for maximum blossoms or in partial shade (although flowering will not be as prolific). It is best to keep Japanese honeysuckles away from other plants. Their rapid growth and vine-like growing habit can strangle other plants.
Fill the tub or barrel until it is approximately 1/2 full with a quality potting mix. Mix together equal portions of compost, peat moss and perlite or vermiculite if you want to make your own potting mix.
Saturate the mix in the tub or barrel with water to help settle the growing media. Wait for the water to fully drain back before proceeding.
Remove the Japanese honeysuckle from its planting pot. To do this, invert the pot. Use a block of wood or a mallet to tap upward along the rim of the pot. When the pot starts to loosen, pull it from the root system. Loosen any entangled or matted roots using your fingers.
Set the Japanese honeysuckle onto the top of the potting mix in the tub or barrel. Keep the honeysuckle level and straight in the barrel or tub while you scoop in mix to secure it in place.
Push the potting mix down and firm it around the Japanese honeysuckle while you pack the tub or barrel with mix. Once the barrel or tub is well filled with mix, water it thoroughly to saturate the mix.
Water Japanese honeysuckles about once a week during the summer growing season. Once established, they can withstand periods of drought.
