Are they lilies?

A few questions and a bunch of pics!

Question 1 / Plant ID:
I went to a housewarming where lucky me, the new homeowners were not prepared at all to plant anything so they passed these lilies on to me. At least I think they’re lilies? Best question of all, how quickly will they take over my flowerbed? haha
The flower, which does not look at all like a day lily and is only about 2 and a half inches wide: (he got a facefull of muddy dirt, woops.)

The whole plant:

Also, I just planted it today (it’d been in a bag for like, two weeks before I got it??) and it’s in a pretty sunny spot. If it needs shade please let me know so I can move it!

Question 2:
This is the clematis that was not eaten by rabbits. The leaves don’t look so good, and it looks suspiciously like what made all the leaves drop off my lilacs last fall. But it could also be sunburn? (it was recently moved from shade to sun…) could it be some sort of fungus?

And everything else!
Front to back: tiny peonies, iris, bee balm, yellow day lilies (you can’t really see those…) and shasta daisies.

Newspaper is the story of my life this summer. I started these in those plastic peat pots then moved them to some bigger newspaper pots. I’m definitely going straight to newspaper next year! Anyway, I don’t have room for more peppers/tomatoes, and don’t know yet where to put the others… And I think the cats have been munching or sitting on the cilantro. :( And my christmas cactus in the back.

In the veggie garden, two of my favorites, snap peas and strawberries! I don’t even cook the snap peas, they exist solely for me to munch on in the garden after work. And my strawberries went insane this year!

I am going to eat you tomorrow!

Columbine. I grew this one from seed a few years ago, I’m so proud, haha. I have a few more of these (Nora Barlow variety), a few white ones (same shape/size, not the traditional type with stems) and a little native/Canadian one too. Some bloomed, but a few did not. :(

Dianthus. I wish I had more!

Pot ‘o Amaryllis! One of many..

These have since been moved outside, been sunburned and windblown… :( Pretty much my whole gardening experience has been ‘learn it the hard way’ but it’s still fun.
