I came across this growing in a crack in a pavement. I assume it's an
escape from some garden, but I don't recognise it.

Looks as it might be something in the old Scrophulariaceae, perhaps in
the region of Linaria or Antirrhinum.

Looks too fleshy for those, more like a flowering sedum or Echeveria.
Does it have white sap? Then, maybe, an Asclepia.

I agree that it looks too fleshy for the usual run of Linaria and
Antirrhinum (Linaria alpina looked the closest match, but even that's
not fleshy enough, and the flower colour is different), but the flowers
are wrong for Sedum, Echeveria and Ascelepias, all of which have
actinomorphic flowers.

lobing of the lower lip is right for Penstemon (see palmeiri for example) but leaves are wrong

Except the flower shape is wrong for those, of course. They have symmetrical star-shaped flowers
Not the right flower shape, is it?

It is a Linaria and probably one of the supina group although that
leads us into on of the largest aggregations within Linaria, which is
not too helpful. Judging by the apparently thickened, obtuse-
mucronate leaves, I suspect it's origins are Mediterranean and a plant
of the maquis or similar habitats. Given a warmer, drier climate on
poorer soil, the leaves would not normally be as broad. The flower
colour is wrong for supina, so I'm tempted to think along the lines of
L. depauperata, which has several subspecies, or at least a primary
hybrid with depauperata as a parent. That's about as far as I can
go. I grew L. supina and depauperata many years ago during a brief
phase when I was slightly 'into' alpines and rockery plants.
Seedlings from them did exhibit varying degrees of veining, as well as
colours from yellow to white in supina and off-white to purplish in
depauperata.

I was speculating on those lines, and had gone so far as to download the
Linaria treatment from Flora Iberica. The figures therein show narrow
leaves with acute apices, but reading the text Linaria supina does
sometimes show obtuse apices. The leaf habit does look a bit more like
depauperata than supina.

Stace does mention a hybrid (Linaria x cornubiensis) between Linaria
supina and Linaria repens, but that's stunningly rare (and probably has
a more lax stem structure).

Thanks.
