How to grow Lonicera Honeysuckle
How to grow Lonicera common name Honeysuckle
Honeysuckle is a much loved garden plant grown for it's beautiful, sweet scent. It is both a climbing plant and a shrub and comes from a genus of around 120 evergreen and deciduous shrubs and twining climbers. Honeysuckle is easy to grow, in the right place. For the best results it needs to be carefully planted in the right place which ideally is with its roots in the shade and head and flowers in the sun. Shrubby Honeysuckle will grow in sun or partial shade. It is a woodland plant and it's ideal conditions are to have roots and lower plant in shade and top in sun. This is not easy to achieve and I find it grows best if planted away from the hottest part of garden. Stressed by too much sun and heat Honeysuckle tends to get mildew and look unhappy.
Honeysuckles are often planted alongside a wall and fences and if they are hot they are not happy and will look miserable, straggling and awash with mildew. To grow well Honeysuckle really need a cool root run with moisture retentive soil.
Honeysuckle is best planted in Spring, Summer or Autumn and given that it is not good for the plant to be too dry, water well until established and during prolonged dry periods. To help retain moisture it is a good idea when planting to add leaf mould or other organic matter.
Honeysuckle can look good trailing over a wall, here is one planted in sunny Guernsey looking really lovely cascading over a white wall.
How to Prune Honeysuckle.
Pruning requirements are a little complicated so it is best to keep the label as pruning varies with the different varieties of Honeysuckle.
Climbing honeysuckle, which flowers in the summer such as Lonicera japonica, do not need to be pruned just cut off weedy growth or cut back of becoming too large.
If the Honeysuckle flowers earlier in the year, cut back after flowering which will be around mid-late summer. Honeysuckle can be quite rampant and so if any variety is getting just too large and overgrown can be cut back by about 1/3 after flowering. A good mulch in the spring is ideal.
Prune shrubby Honeysuckle after flowering which again will be mid to late summer.
Which are the best Honeysuckle to grow
One of the main reasons for growing Honeysuckle is the scent, so it is important to pick a variety with scent as not all varieties are as sweet and powerful. There are varieties which look very attractive, will produce good berries, but are not scented such as Lonicera × brownii 'Dropmore Scarlet'.
The best varieties of Honeysuckle to grow for scent are Lonicera japonica 'Halliana' AGM image left, evergreen or semi evergreen and a vigorous climber growing to around 10 meters. Note it really is vigorous and in the right place will make a very large climber make sure you have space for it. Many complain of that this variety is more mildew prone.
Another climber is L. periclymenum 'Graham Thomas' AGM is a good variety, H6 which means it is hardy everywhere in the UK , deciduous, with good perfume and illustrated above right and will reach around 7 meters. This tends to be the most highly praised of Honeysuckle and a good all round choice. Lots of creamy flowers all summer followed by bright berries.
Lonicera periclymenum 'Heaven Scent' which is as the name suggests, is very scented, and a fast growing fully hardy climber. It is more compact reaching around 3 meters.
Of the shrubby varieties those with scent are L. fragrantissima, which is less hardy, requires a sheltered spot and flowers in late winter and early spring. Also L. × purpusii ‘Winter Beauty’ another winter flower variety. Both grow to around 2.5-3 meters.
All honeysuckles produce lovely berries which are picked off by the birds in the autumn and winter. The scent of a Honeysuckle is strongest at dusk and is attractive to moths. Ideas for plants which are attractive to bees butterflies and birds
Honeysuckle can be prone to aphids and given their attraction to wildlife it is a shame to spray them unless with soap and water to wash off the aphids. If blackspot is a problem you can prune off the worst affected after flowering and healthy growth should come back the following year.
