Kaprifol - Lonicera periclymenum - is 'honeysuckle'. The Swedish name comes from Latin caprifolium, in the 13th century back-translated into Latin from German Geissblatt – ‘goatleaf’, named for two reasons: the plant climbs like a goat, and goats like to eat the leaves. (J. Corneliusson, Växternas namn). Capra is ‘goat’ and folium is 'leaf'.
Honeysuckle comes from Old English hunigsuge – there is abunant nectar in the flowers for nightflies to suckle.
The genus Lonicera is named after Adam Lonitzer, a German 16th century botanist. Periclymenum comes from Greek periklymenos ‘well renowned’.
Other well renowned members of the Caprifoliaceae family are elder, guelder rose, and linnaea (twinflower).
The honeysuckle is still in flower today, in spite of yesterday's frost.
