Have ~ 8 Purple Cone Flower plants if you are interested. Yard is mostly shade / part shade so curious to have anything you are looking to get rid of for shade. From looking at your list, also curious about your river birch. If you aren't interested in the cone flowers, I may have other options to trade for the right river birch.

would you like some mixed hollyhocks? i like your Helianthus maximilianii (Maximillian Sunflower) and your 4 Oclocks (mixed)

I received 3 helianthus "lemon queen" for mother's day. Unfortunately 2 of them didn't make it, but the 3rd one did... just barely. Seems, as the plant was just taking off, a ball from over the fence broke most of it off. It has since regrown but hasn't bloomed yet. I also just received 2 replacements from the company my daughter bought the originals from and will plant them as soon as it stops raining. (I may just have to build an ark if it doesn't stop soon!) I've also acquired some Boltonia from a neighbor and bought a black sambucus. Let's see... from seed I started some perennial sunflowers and heliopsis. Most of the new perennials did pretty good this first year but I imagine they'll do even better in the coming years! In the meantime, to fill in the gaps until the perennials fill out I planted tithonia, annual sunflowers, along with scarlet runner beans. Next spring I'm going to transplant a clematis too. All in all it was a successful year keeping the little darlings at bay. They've also made friends in the neighborhood and, now that they're a little older, mom lets them go to the friends' houses so most of the time they're gone. Peace at last. Thanks to everyone for their suggestions!

I didn't do anything except participate in the swap - this is Beverly and Mimi's baby and I will join you in thanking them for a job well done. I think the sunflower you are referring to is helianthus maximillian. I was delighted to see two of them there and did my best to "sell" them. It's a perennial branching sunflower that's native in hoards in the central plains, among other places. There you will find them in the roadside in the fall loaded with blooms. I have one in my garden that has divided this year and I can't wait to see the blooms. I have heard that it is not agressive and makes a good bedding plant. It was great for me last year, so we'll see how things this year. Sorry we didn't get a chance to meet. I was pretty beat after the Race for the Cure.
