Hi Harry,
This is Pentaglottis sempervirens, aka 'Green Alkanet'. It is related to forget-me-nots and garden borage. While it is a perennial that is generally green year-round (hence, 'sempervirens'), it prefers moist and shady places. I guess it figured that spot was finally moist and shady enough to pop up again after our dry summer! It is not native here, but from Western Europe.
In looking up where it was from, I discovered a new word! This plant is apparently a 'calcicole', or 'chalk-dweller' - Wikipedia says that it, like ash trees, honeysuckle, and some others, can show signs of aluminum toxicity and phosphate deficiency under acidic soil conditions. That would explain the reddish coloring I often see on honeysuckles...
All the best,
Tanya
