Besides the ones you listed, i would add:

swamp sunflower (which grows like a weed some places, but i like it)
heliopsis

This is only my second year in my garden, and I had mostly annuals last year, but I also love cutting roses, coneflowers, daffodils, glads, crocosmia, hostas and ferns for greenery, and I know they're not perennials, but I love hydrangea, camellia and gardenia blooms.

Although I don't grow these in my garden, I love peonies, tulips, delphinium and lilies.

Now if I could just figure out how to keep my cat from eating any plant or flowers that I bring in the house! :)

Catbird, what peonies do you have in your garden that do well for you? I was so tempted to buy some at the BBG spring plant sale but chickened out because I had heard that they can be so finicky here!

haley: I don't even know what varieties my peonies are. One came from the garden of my daughter's 70-yr-old house in NC after they bought it. (They're pink, which I love and she doesn't.) The other is a generic I ordered from Greer Gardens some years ago. Both are beautiful, but have started getting mildew half way through bloom season. I think if I divide and thin them out this fall they'll be fine, though.

Hydrangea, camellia and gardenia are perennials, they're just perennial shrubs, not herbaceous perennials -- and they're great additions to a cutting garden.

Tood: Thanks for suggesting the heliopsis. Don't think I have one of those.

Please add butterfly gingers to your list. Peach, Yellow, white; beautiful and fragrant. The Kahili gingers are great as well. How about oakleaf hydrangeas. Also the monardas.

Obedient plant is another that probably makes a good cut flower. It reseeds
itself so successfully, you can have lots and lots if you wanted.

Haley just touched on lilies, they make a magnificent display. Asiatics or LA hybrids, maybe a few Orientals or Orienpets. I wouldn't do a whole bouquet of Orientals though, it might over power your room.
My gardenias are in full display so I've been bringing blooms in and placing them in a bowl for a quick fix..er sniff.
I never thought about bringing a whole inflo of butterfly ginger inside, I usually just pluck one bloom and tuck it behind my ear.

Kabby, the first time I saw a display of butterfly ginger was at a flower show at a banquet at the Commerce Club in Atlanta. It was magnificent. The aroma was intoxicating. I've been in love with them ever since.

I love zinnias as cut flowers. I just received some obedient plants as trade, and cannot wait to see how they do.

Dana: A word of caution re obedient plants: Be very careful where you plant them. They will take over any bed you put them in, so plant them in a spot where they'll have lots of room to spread or where they will be contained, like between a sidewalk and the driveway! I made the mistake of planting some in a perennial border, then spent several years trying to get them out of it. Obedient they ain't. ;-) Alice

P.S. Zinnias are annuals, not perennials. ;-)

ooooops... right you are catbird....
