Rita78 said:Three areas where I had Ajuga growing well died off over winter (central wis., zone 4-5). What happened? A couple other spots are fine. Thank you.
As Philip mentioned, could be micro-climates (different very local conditions). Did some get more snow cover than others, or were some covered in ice or standing water, are some closer to the house wall, sun versus shade etc.?

Ajuga acted weird for me too (another year). It volunteered over a large area, under a redbud, then UN volunteered, and a lot of violets came up. My spot is dry, maybe we had a wet year or two that started this. It seems to be more lush in moister places, no surprise)
