File:Asarina procumbens cascading down wall beside Paxton church gatepost.jpg

English: Colony - or possibly single plant with multiple points of emergence - of Asarina procumbens growing out of wall beside church gatepost, Paxton, Scottish Borders. 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 specimen seen here has a cascade of growth trailing from a network of woody stems with roots deep in the crevices of the Berwickshire sandstone church wall. Smaller plants (or offshoots) are rooted/emerging at the juncture of wall and tarmac pavement (U.K. sense), sprawling over the tarmac and accumulating detritus around their sticky mats of foliage. The plant(s) was/were flowering profusely - much to the delight of the local bumblebees, who were burrowing deep into the pale snapdragon-like flowers, in search of nectar.

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).
