These berries frosted and have an elongated shape, approximately 2 cm long and 0.5 cm (0.2 in) in diameter. They have a tart taste similar to blueberries and kiwis. Rich in vitamins B and C, they can be consumed fresh, used in jams, jellies, juices, or frozen. When cooked, the flesh turns a mahogany red colour.

Shrubby honeysuckles, lonicera: planting, pruning and maintaining

Read article

Honeysuckles consist of bushes or generally vigorous climbers that wrap around their support with a magnificent flowering that is often highly fragrant. Bush honeysuckles, commonly referred to by the name Lonicera or Honeyberry, are sought after for their dense foliage which is well-suited for hedging or as ground cover, but also for their flowering which, for some deciduous species, diffuses powerful scents in the heart of winter. They are highly valued for their ease of cultivation and rapid growth, allowing for the establishment of hedges, borders, or ground cover in record time with shoots of 30 to over 40 cm per year. Their slender stems bear opposite, glossy green leaves or those with a velvety appearance, sometimes slightly purplish, and flowers in open tubes with 5 lobes, ranging from white to red, followed by round berries in summer. Notable among evergreens is the <a href="https://en.promessedefleurs.eu/shrubs/shrubs-by-variety/honeysuckle/lonicera-nitida-box-honeysuckle.html">Lonicera nitida</a> with small dark green leaves, ideal for forming beautiful, bushy, compact hedges, or the <a href="https://en.promessedefleurs.eu/climbers/climbers-by-variety/honeysuckle/lonicera-periclymenum-chic-et-choc-common-honeysuckle.html">Lonicera periclymenum 'Chic et Choc'</a>, a dwarf variety with pale pink to orange-yellow flowers suitable for pots or borders. Among deciduous varieties, the <a href="https://en.promessedefleurs.eu/shrubs/shrubs-by-variety/honeysuckle/lonicera-fragrantissima-winter-honeysuckle.html">Lonicera fragrantissima</a>, semi-trailing, offers a very long flowering of pearly white flowers that are very pleasant to smell in the heart of winter. Honeysuckles are hardy plants, capable of thriving in the most inhospitable soils as long as the soil is well-drained and cool in sunny situations or preferably in partial shade or even in the shade for the species pileata. Pruning involves shortening the branches just after winter by removing old wood. For hedges, intervention is required two or three times a year. Loniceras are used in borders, hedges, or trained against a wall.

Planting and care

The Honeyberry appreciates moist soils and dislikes dry and very chalky soils. Choose a sunny or semi-shaded position in hot regions. Planting should take place in autumn or spring. Space the plants about 60 cm (23.6 in) to 1 m (3 ft 4 in) apart.

Soak the root ball for a few moments before planting. As the Honeyberry dislikes dry soils, add a slurry made of water and compost to the bottom of the planting hole. Add the young plant, cover with soil and compact the soil to form a small watering basin. Water.

During the summer, apply a mulch at the base to retain freshness and moisture.

It is also possible to grow this plant in a pot.
