Thanks, RJ.
Very interesting to see all these pictures. It's extremely interesting to see seasonal changes (e.g. as old leaves break down and new ones come in).
For instance, the old leaves on Variegata/Dawson's White do seem to die off very markedly around the pale edges, perhaps irrespective of the growing conditions.
It's also nice to hear that Variegata/Dawson's White doesn't seem to invariably end up with reversions. The bit about stress causing reversions is just something which I read in one source. Perhaps that claim is incorrect. As noted, it was my (apparently) less stressed two plants that have reversions this year, not my (apparently) more stressed one. Perhaps it's the opposite; the more stimulated the growth, the more the likelihood of the revisions.
Was also an interesting question asked previously about any light/shade effect on Brunnera leaves, including their patterning. Apart from necrotic/dead bits in older leaves, I've never noticed/paid attention to other possible changes like fading. Will have to look closer.
For us, I do feel it's worth focusing on perennials like Brunnera. There aren't many workhorses of our mixed perennial beds in spring. For us, besides bulbs, it's lungworts (Pulmonaria), primulas, Brunnera and the hellebores I've been adding that are the stars of our beds in spring.
