Friday Fabulous Flower - cute weed

Lots of rock/brick walls where we are in Italy, and lots of different weeds growing on them.  Several are quite nice plants for filling rough spaces.  Here's  one that has a lot of common names; the one TPP learned was Kenilworth ivy.  Yet you will probably recognize right away the similarity to snapdragons to which Cymbalaria muralis is related now placed in the much larger Plantaginaceae, the plantain family along with a number of other scrophs.  TPP is still having trouble with this as it does not make taxonomic sense to his antique mind.  The flowers are quite cute with a nectar spur (note the center flower) and very reminiscent of a Linaria.  It is viney and grows in a dense mat of ivy like leaves.
