Woo-hoo...I get another chance to be wrong tonight! If the yellow flower in 2-b is not Medicago lupulina, would the person who does know please tell one or 2 distinguishing clues!

Oh Mytime, you'll never catch up to me for being wrong, lol.

The plant in the middle of the second picture is Lonicera, that can be taken out. I have no idea what the plant at 4:00 is, does it have any fragrance? the plant at 7:00 in that picture is Astilbe, you'll want to keep that.
Picture #3 also looks like it could be Astilbe.
Pictre #4 has Sidalcea in the middle, the dying foliage at 4:00 is possibly daffodils, surrounded by Iris which have the purple at the base. Those are indeed Sedums, it could be Siberian Iris at the back, but it could be something else as well. I think the one directly behind the Sidalcea could be a daylily.
Plant #5 looks like another Lonicera. the Rose looks like Sweetbriar, Rosa eglanteria. If it is, the foliage will smell like green apples after it rains.

I think the second one (yellow flowering) is the non-native Melilotus officinalis.

Mytime, #2b is not Medicago lupulina just because that plant is generally prostrate rather than upright. The plant in the picture appears to be upright and taller than Medicago gets. Although I don't think it is Melilotus officinalis either. Flowers don't look right for it to be sweet yellow clover. I'm not familiar with hop clover (Trifolium campestre) but that seems like a closer match.

#2a - the righthand corner appears to have some sort of oregano or marjoram variety. Foliage should be very fragrant (in an herbal sort of way) if it is.

The clover looks like Trifolium aureum. There are three species of yellow clovers that are quite similar, but that one has sessile leaflets and stipules about as long as the petiole.

Fatamorgana and Lycopus...thank you for the details! I went back and reread what I read last night on the M. lupulina, and there it was right in front of my face..."often lying flat." I think I should restrict my learning to mornings with coffee, not late evenings with other adult beverages.

Mytime, coffee...adult beverages, thanks for the giggle! We all take our turns at learning. The other day I said plantain isn't purple at all and Carol posted a picture of a very nearly all purple one. News to me.

I like Thomas Jefferson's quote, "but tho' an old man, I am but a young gardener." Aren't we all?

FataMorgana

jeanne: Aww, can I leave the first lonicera or am I likely to end up regretting that? I like the color and the shape, especially early in the season when there's nothing going on over there. I WISH that was an Astilbe, but it is Trumpet Vine. Eek... just last week I was thinking "I know there were daffodils around here somewhere. Where are they!?". Now I know :( I just checked, and that is a daylilly. I don't think the rose is a Sweet Briar.

Fatamorgana: Ahh, oregano. Thank you! I took a whiff, and I knew I knew what it was, but for the life of me, could not think of it.

Thank you everyone!

The clematis looks like my Jackamani. I might have spelled that wrong.

Carmendavis: Jackmanii and EV look a lot alike to me (but my eyesight leaves a lot to be desired, haha). I went with EV because it has smaller blooms. Mine measure ~3" or so... but maybe that's from neglect, and it will surprise me next year. Assuming I ever find the will to go back outside :\

If your rose has black hips in autumn - could be a burnet rose, or perhaps Stanwell Perpetual. First up and last to bed. I think the burnet has its thorns more densely packed along the stem but Stanwell is more bristly.

vetivert8: Thank you! I spent another afternoon sifting through rose sites recently, and double burnet is the only one I bookmarked. I'll definitely keep an eye out for hips in fall. Or maybe I'll post pictures of the actual bushes before I prune them (I hate to do that because they really are a horrible, embarrassing, sad, pathetic mess right now)
