If you take a walk through the wilderness on campus during spring, you may well stumble across some beautiful honeysuckles coming into flower: they’re not quite so easy to spot at this time of year (Winter) without the distinctive bloom, but are one to look out for later.
Honeysuckle Lonicera periclymenum, a species found on campus, is a member of the family Caprifoliaceae, which also includes the Elders and Snowberries as well as the other honeysuckle species (Stace 2010). As a family, they are recognisable by their opposite leaves, flowers forming heads or umbels (all flowers branching from the same point), petals formed into a 5-lobed tube, with 5 stamens (the male reproductive parts) in the flower, and for the species in the British Isles, bearing a fleshy fruit.
To spot the Honeysuckle more specifically, look out for a twining shrub (one that coils itself around another plant or structure for support) with creamy-yellow, 4-5cm long, flowers that are trumpet-shaped and in a whorled head. The petals form two lips: the upper of which is curved upwards, and has four teeth, the lower of which has no teeth and is much simpler: the stamen protrude obviously from here. The flowers are also often pinkish-purple around the outside, and have a lovely fragrance! The fruit develops as a red globular berry.
Lonicera periclymenum is known simply as ‘Honeysuckle’, but you can also look out for Himalayan Honeysuckle (Leycesteria formosa) on campus, which has more reddish flowers, which are later replaced by purple-black berries, that hang in long spikes surrounded by purple bracts. At the moment (January) you can still see it with the remnants of last years berries between the Lyle building and Harris Garden.
Good luck on your Honeysuckle hunt!
