Thanks for kicking this genus off with Scutellaria incana, Mark!
Here's one of my current faves which I believe is S. orientalis ssp. alpina (from the flower colour and leaf dentition, primarily). It gets to about 15 cm tall here in regular soil. The flowers are quite delicately coloured when fully extended; many of my photos give them a greenish cast (second photo)... weird camera effects, perhaps.
