File:Asarina procumbens flower pollinated by Bombus hortorum.jpg

English: Garden bumblebee, lying on its belly, so deep inside a flower of Asarina procumbens, to feed upon the nectar, that only the tip of its white-furred tail and its hindmost pair of legs still remain protruding. Asarina procumbens, the trailing snapdragon, is a protected wildflower native to the Pyrenees, which has nonetheless proved capable of thriving as an attractive weed in some harsh urban environments - notably in the Australian city of Melbourne.

The single flower shown here was borne by one of about four specimens (or possibly a single specimen with multiple points of emergence) growing out of a wall in front of the church (site of the Old Smithy) in the oldest part of the village of Paxton, Scottish Borders (near Berwick-upon-Tweed).

Several specimens of this plant are said to have been growing at this site for quite some time. Given the proximity of the extensive gardens of nearby Paxton House the species may represent either an escape or a deliberate introduction from that estate (around which the village grew).
