Also seem to have lost one Turk's cap based on the fact that the other one is growing on well now and perhaps one beauty berry again, based on comparison to its peer.

Teri, false nettle dies back completely on top in the winter every year here, but returns reliably very early in spring. It makes new growth from the bottom, plus tiny seedlings come up around it. If yours hasn't shown any sign of life yet, it's probably dead. The only thing that will kill false nettle here is extreme dryness - if yours was extremely dry at any time last year, it may have been weakened enough to not survive.
I don't know about the eupatorium - that type doesn't grow here.
Turk's cap comes back every year with a vengeance here, spreading all over the place, but it does originate in Mexico, so if you had excessive cold last winter, that could be the reason for your loss. But don't worry, the one still alive will grow like a weed!

Interestingly the false nettle just made its appearance today. I replaced the boneset yesterday with one I bought at a native plant sale, hope I didn't jump the gun on that. Still no sign of the other Turk's cap, guess I'll need to replace that as well. At least it's easier to come by!

That is strange that the FN came up so late, Teri. Mine has been up here in OKC since early spring, and is now about a
foot high. I have lost FN before, though, in the 2nd year and had to replace it. It does reseed, but not invasively.

Turk's cap is supposed to reseed a lot, so maybe you'll get some seedlings.

A plant that I was totally surprised about was Flame Acanthus. Do you have that? It is a Texas native, hardy to zone 7. I grew some from seed last year and planted them out. No blooms, but I wasn't too shocked because some perennials don't bloom their first year from seed. It was one of my earliest plants to put on foliage - it is a shrub, so I didn't get a chance to cut it back and good thing. They leafed out just fine and are now in full foliage growth. Gets about 3-4' tall eventually, and both hummers and butterflies alike are attracted to the tubular orange-red blooms.

I lost my Turk's Cap, too, but it really is only hardy to zone 7B. We had a very cold winter so I wasn't surprised. I'd think it would winter over in your area, though.

The Eupatorium species I have no clue about.

Here is a link that might be useful:

I have the acanthus and one of them is fine, the other has about 3 leaves down on the stem. :-( Pretty pitiful looking. I'm waiting for it to green up a little more then I'll trim the dead stems.

What is surprising me is that I had a bunch of Tropical Milkweed come back from the ground, I never expected to see that.

Weirdly, none made it last winter and this winter was worse.

My viridis is up and about to bloom now and I still occasionally see a faded monarch but I know it's about too late down here to hope for any spring eggs. Monarchs seem to hit us more in the fall with eggs.

I keep looking though and of course the queens can still use it, so I'm glad I have it anyway.
