Thanks all.
I hope I didn't give the impression plants were only first poking out of the ground. They are well underway, so the ones mentioned are the only ones showing NOTHING which concerns me.
mnwgal - I was hoping you would chime in since we're probably close by. Now I am concerned about the hydrangia. That was a new shrub last year and I have no experience with these at all. I just couldn't believe they are this late in emerging, so I have a feeling that one is a goner, but I'll wait a bit longer. My brugmansia has been in the ground for well over a month and is looking spectacular. The new growth is exceptionally lush this year because of all the rain.
campanula - Yes, I did the scratch test and did find some green on the larger branches, but whether or not it is true living green or just some leftover dying green is the big question. I wasn't even going to mention my hibiscus which I know is a late emerger.
idabean - I'm happy you mentioned the temp thing. I was wondering if some plants like caryopteris need a certain amount of warmth to leaf out. We were stuck in the 60's for weeks, but now it looks like mid 70's to low 80's are going to be the norm. Last year these were well leafed out in March, but it was a warm year.

funnthsun, that is funny about the clay added. I guess what I have read clay is a great soil mix.
FYI..... I add the peat because we do not get good rainfall in the summer and the clay gets hard, dry and kill the plants. Clay is great if it is moist and stay moist but no rain for months and 90 degree temps will kill your plants.

It's too green and could benefit with some contrasting leaf colors and flowers other than white.
Kevin, when you have time you could put in some variegated Polygonatum to address leaf colour and a corydalis lutea and or a ligularia to get a yellow shade flower. (The ligularia would give a different foliage height to your garden which I find visually appealing).

Thanks for the comments and responses.
Yes, I could add some other plants and the suggestions were good ones, but I'm still very content to not do anything. Maybe that notion will change with time, but so far the desire to do so hasn't hit me.

Actually, there is a planting of that on the other side of the azalea which you can't see in the photo. I divided and moved a bunch of that last fall and only kept a limited amount. I threw away buckets of that stuff, so it's going to be a few years before my patch is large enough to divide again.
Dee - No, I'm not concerned about the carpenter ants. I had those years and years ago long before this garden was created and haven't had a problem since treating for them back then.
As to the possible problems with the Podophyllum, I admit that will be an interesting situation to deal with. I did dig some a few years ago and found that it comes out of the ground very easily, with a garden fork. I don't think I'll try to dig it out however. What I'll probably do is just cut sections of it down early in the spring and keep at it if it re-sprouts. If a plant can't photosynthesize because the leaves and stems are gone, it will eventually die. I had that problem with wild, white violets at one point in time and that technique worked on them.

So after reading Jelitto's website more closely, it was actually â¬12 per GRAM of seeds. Still not cheap, but much more reasonable.
They state these seeds do not necessarily need a cold period to germinate so I went ahead and ordered some. They were slow to ship but customer service was very reliable and informative.
I sowed them last night in small pots and will now keep my fingers crossed for good germination. I would like to have some nice small plants ready for early fall planting this year, but I still have a few seeds leftover for wintersowing if it doesn't work out.
I now regret not ordering the Gold Nugget (primed for rapid germination) seeds of Thalictrum rochebruneanum...

I have heard the regular Geranium phaeum color is not a garden standout, but there are so many color variants available. I don't yet know how deep rooted this plant is, but maybe you could start with a mess of clones with different bloom and foliage colors and then rogue out any undesirable seedlings as they arise?
Geranium maculatum comes in a limited but beautiful color range from pure white to light pink to mauve to dark blue-pink. It is lovely and charming in all of its variants with colors that are never foo-foo or flat. The flowers always glow like beacons in the shade. It is even available with stunning bronze foliage that is surprisingly iridescent and stands out wonderfully, even in shadows. I much prefer 'Elizabeth Ann' over 'Espresso' for a dark-foliaged clone since it is taller, the flowers are larger and prettier, and because I think it is a generally superior clone. This species is very easy to transplant (or weed out, depending on your point of view) and handles heat and drought by simply going dormant for the rest of the season. If it gets enough moisture, however, the foliage will stay looking nice until it develops good autumn colors before dying down.
Also, for good spreading spring ephemerals don't overlook the smaller bulbs like Eranthis hyemalis, snowdrops, Siberian squill, Chionodoxa, Crocus tommasinianus, etc. And then Cyclamen hederifolium for autumn blooms.

cheers, Ispahan. Yep, bulbs are likely to be my first investment. The ground cover is negligible in the spring woods and poplars are late into leaf so am planning a major spring bulb show. The little blue bulbs are always good value and will probably go for 'in the green' planting for the snowdrops and bluebells.
Having ordered seeds for various large campanulas, including the dreaded rapunculoides, I have been amusing myself re-reading the various warnings about this evil beauty. Some garden writers really let their hair down when it comes to this bellflower. When it comes down to it though, I would rather have 5 acres of campanulas instead of 5 acres of nettles and hogweed.


"Horatio - I've read very good things about this one. I think it's one of the current favorites.
So far Zweiweltenkind is doing really, really well in its new location, but we haven't had any warm or hot weather yet - you know this never ending early spring weather this year. I'll see what happens when the scorching stuff sets in if it ever does.
When I moved this plant, I divided into 3 pieces. Right now the sum of those 3 divisions is much, much larger than the original plant if that makes any sense. To me, that says it's happy.

Painter's Palette
Latin: Persicaria virginiana
If you let it flower you get some that are this color

and some are green/purple/red like this. It is the plant behind the fairy house

I second what eclecticcottage said... Hostas were mine. As booberry85 said, they seemed the plant to get when you want to throw in the towel, especially here it seems. It wasn't until I got more into gardening that I started to appreciate them. Not to sound like a snob, either, but driving around, looking at houses with hostas in the landscape, now I can see when, where and how they're used either correctly or not. I still agree... I think a lot of people use them when they give up, have no clue, just want to be done with it, etc. but they do serve a great purpose and if used correctly can really make a garden.
I also have to say... I'm terrible about thinking of using shrubs and things. When I first started this gardening thing (yes, gardening thing... to emphasize the insanity) I thought "who needs shrubs". Well, turns out... me. The one area that I redid that features a shrub is probably my favorite garden, so now I'm going back to other areas and reevaluating what shrubs I might be able to move in ha ha

Highly doubtful. They are hardy to the high 20s only and we get substantially below that for sustained periods of time, even in our mildest winters. You won't be able to trap enough warmth to keep them going outdoors. Have you thought about trying to overwinter indoors?


I typically plant in a diagonal pattern, staggered rows, if you will, so it doesn't really look like actual rows, but it is easier to plant than random, I think. I'm no formal gardening girl, but I don't want to put a plant at the back that you can't see because it's too short! That is what I'm trying to avoid, more than anything and I don't want a color issue. I plant more by color and texture than anything else and obviously by height.
I lay all of my beds out on paper, too, before I plant them. With my last one, I'm at about 80% success rate with 20% moving/replacing thus far and this is it's first season, so I understand what you mean. I still think it helps to start from paper, I am much more creative that way than just standing out there, randomly planting. I have no preconception that everything will stay that way, though. Best chance for success starts with forethought, though, I think.
Thanks for the good luck! I am excited about this bed, echs are my favorite flower, so I am really happy that I can have a whole bed of them. :)

I think I have solved the problem, at least I hope. I think if I put the ruds along the 3-foot and 7-foot side of the bed, that will still basically be against the house and will serve as a backdrop for the echs. I think that will work. If not, then I can change it up next year.
Next question on this bed for ech lovers:
If you were starting a raised bed for echs, what blend would you use for the soil in this bed? In other words, what's the best mix of soil for an ech? The bed is about 16" deep, fyi. I have my own ideas, but, as always, some of you may have a better one. Percentages would be helpful! Thanks so much!

Here's the ech beds so far this year. The paradox, pallida, and crosses with them are the first to bloom. Only a few of the hybrids have bloomed yet.






Just want to give a word of praise for G. maculatum 'Elizabeth Ann'. It is a stunning, easy care bronze-leaved selection with no disease issues. I much prefer it to 'Espresso' (which has equally wonderful foliage) because it is taller with larger blooms. Flower color on 'Elizabeth Ann' is a light almost pure lavender with just a hint of pink, whereas 'Espresso' runs more on the light pink side. A clump of 'Elizabeth Ann' is spectacular in full bloom and the foliage is surprisingly visible in shade. I am hoping to find a few bronze leaf seedlings around my plants in the future.
I have not tried a dark-leaved clone or strain of G. pratense, but I am now on year 2 with 'Violaceum Plenum'. It has been very slow to establish for me but I was pleased to note the other day that it is sending up two bloom spikes. No mildew last year or so far this year. I recently added 'Elizabeth Yeo' and 'Mrs Kendall Clark', so I will see in the future how they perform for me.
I tried it twice and it died both times, and I have a lot of geraniums. Last year I bought the dark leaved Hocus Pocus, and it has barely stayed alive. Never had mildew on any of my geraniums either.
