The irises are in full bloom (also have some Siberian irises that have bloomed and some Japanese that have not.)

The edge of the garden is this grass/weed ? What is it? Pulling it out will effectively kill it for next season? (sorry the photo is not in the right orientation)
4

Another plant in the bed .. not widespread .. but dont know what it is

Then on the edge of the property .. here are some other plants .. probably voluntaries .. don't know what they are

10

This variagated ground cover is popping up from under the ivy. What is it? Will it grow in shade with my veriagated periwinkle?
11

Another ground cover next to the pachysandras. I like this .. It dies in winter and comes back in spring
12

And couple of trees at the border .. voluntaries, don't know these either. One flowers, the other doesn't

phew .. now I think most of the plants I wanted to know about are photographed/uploaded/posted in the thread. (There are probably 50 kinds of weed in the lawn that I may/may not seek information about later :) )

2&3) Definitely a weed, though the name is escaping me right now. Since they are so big and tall, hand pulling is your best bet.

4) Also a weed. Could probably be taken care of with some round up.

9) Looks like a hydrangea. Are the blue flowers - do they kinda look like big blue snow balls? If so - that is hydrangea. The color can change due to acidity of the soil.

11) I'm not sure what it is, but it has shown up in my shade garden on it's own. It's been there for 2 years now and hasn't flowered. But I like the visual interest, so I leave it.

13) Looks like some type of apple/crabapple volunteer. Does it make any small fruits in the fall? Though it may still be too young to.

2&3 Curly dock, a weed with a tap root, so dig out with a tool that is narrow and deep like a dandelion digger.
4 sorrel, a weed with fine underground runners. Have to weed often and as completely as possible to get rid of it as it resprouts from roots that break off or Roundup works on it relatively well. Pull before it goes to seed (tall stalks currently on it are either blooms or seeds)
5 False Solomon's seal (Smilacina racemosa), a nice wildflower. Will slowly increase if you let the berries develop.
6 I'd guess a weed (but not sure) since I have a weed that comes up in my garden that looks similar
7 & 8 Lilac - should have scent
9 Hydrangea probably
10 Leucothoe
11. Euonymous- keep an eye on it and prune where you don't want it as it will spread, but not rapidly
12 Gout weed or Bishop's weed (Aegopodium)- will spread and is hard to remove since will sprout from any little root. If not contained I would consider taking Round-up to it before it gets totally out of hand (though you will have to keep the Roundup off other plants as it will kill them also)
13 Apple most probably or crabapple
14 Musclewood AKA Amaerican hornbeam (Carpinus caroliniana) Nice small native tree
15 Not sure, but if a pair leaves come off exactly opposite each other on the stem, it's a native viburnum, but I can't remember which off the top of my head
