You guys are always so helpful identifying plants! I really appreciate this service!! Here are a couple for (almost) June:

Thank you for your nice comment! We're happy to help.

Plant #1 is larkspur.

Plant #2 looks like a type of pennycress.

Plant #3 is hyssop.

Thank you for confirming my guesses! Would you happen to know species?

There are different cultivars of larkspur. A common annual species is Consolida ajacis. http://www.missouribotanicalgarden.org/PlantFinder/PlantFinderDetails.aspx?taxonid=263223&isprof...;

Pennycress is Thlaspi. Common species are field pennycress (T. arvense) and thoroughwort pennycress (T. perfoliatum).

Hyssop - Agastache foeniculum

Wow, thank you! So... larkspur is an import!? I thought it was native Delphinium. So similar. That’s a bit disappointing to hear because I got it in a supposed bee garden mix, and now have a lot of it. I decided to yank out the pennycress. I saw the Agastache in someone else’s garden and liked it, so may plant some of that.

And another question: I know this is some sort of morning glory type vine, but is it a native species? It appears as though something likes to eat it:

There are two native larkspurs (Delphinium sp.) in Maryland but they are rare and are not available in commercial seed mixes. https://www.marylandbiodiversity.com/viewChecklist.php?genus=Delphinium

Your next plant is hedge bindweed. https://extension.umd.edu/hgic/topics/bindweed
It is native, but beware, it is an aggressive grower. https://www.marylandbiodiversity.com/viewSpecies.php?species=2402

The plant with the pink flowers is Spiraea. https://www.marylandbiodiversity.com/viewSpecies.php?species=3691

Many thanks, Christa!! As you may have guessed, I’m trying to grow an all-native garden, so I truly appreciate your answers to my questions. Yesterday I watched a black swallowtail feasting on the larkspur, so I think I’ll keep, but not expand it. I’ll take your advice on the hedge bindweed, and continue pulling, but not get too stressed if I miss some. As for the Spirea, it was at a friend’s yard. I think I’ll pass on planting it in mine, even if it is pretty.

The first plant looks like a type of beggarticks (Bidens sp.). https://www.marylandbiodiversity.com/viewChecklist.php?genus=Bidens

The second and third plants look like Arborvitae and Chamaecyparis, respectively, but it would be helpful to see photos of the whole plants.

Thank you, Christa!

The maybe-Bidens: I’ve taken another shot to hopefully narrow down species, but I suspect the flower will be the final answer.

I’ve added two additional photos (same sequence as my last post) of the evergreens (whole plants) as you recommended.

We can't tell you which Bidens that may be.

Your second photo looks like Chamaecyparis and the third photo looks like a globe Arborvitae.
