Small leaf, very compact.

My first thought was privet, but your description doesn't agree. Maybe
privet honeysuckle (Lonicera pileata).

These seem to be multiplying. Leaf starts out green, quite quickly
becomes variegated and I think ends up with a little white pointed
flower. Invasive?

I agree with the identification as Houttuynia.

I'm not trained up in the differences between Convallaria and
Polygonatum, but Polygonatum multiflorum, Solomon's seal as suggested
elsethread seems a sensible suggestion.

Looks like a willow-herb (Epilobium), but I'm not completely sure.

These look like the beginnings of gladioli. There were just a few
isolated ones in the garden last year so I'm wondering how such a
tightly clustered bunch will fare. Will these all flower or will they
die in the crush? Or are they not gladioli?

Possibly montbretia (Crocosmia x crocosmiflora); monbretia do develop
into dense clumps.

A lot of patches of this on old walls. Tiny little flower.

Ivy-leaved toadflax aka Kenilworth ivy (Cymbalaria muralis)

- thanks for any help...
