The Scrophs (or is it now Plantaginaceae?) are split between Penstemon, Castilleja and Veronica...which leaves out a few odd ball cousins like Paederota, Synthyris, Calceolaria and a few other wierdies I have an excessive fondness for...including Scrophularia. This is actually quite a large genus of mostly rather homely plants, although I am quite fond of many of them due to sheer stubborness or perversity. Who knows. I have grown this little hummer on and off for several decades: I think it is largely Western Asian, although I grew a very condensed cousin from Central Asia I obtained from Josef Halda for many years that I miss a lot.
Not much more to be said about it, but it does make a good combo with Hyacinths....
