This was supposed to be lilies of the valley, with ground cover in between.

On the left, Omphalodes verna.

On the right, Tiarella cordifolia.

The latter is by now purely theoretical-historical; I can’t spot a single live specimen. Already two years ago they weren’t doing so well, and now they’re all gone. I can’t say it makes me happy, but it is definitely interesting that a supposedly reliable ground cover plant for shade is not just languishing but just completely gone after a few years. It really didn’t like this spot.
