Unhappy thalictrum

in Problem solving
I am new to growing thalictrum and unfortunately it doesn’t seem to be going well so far. They have been in the ground for a week and are looking rough: these spots more or less throughout, a bit of yellowing in the lowest leaves, and the top stalks are wilted. I’ve been keeping them moist but not soggy. They are shaded for most of the day but get direct sun from about 3-5. 

I’m especially wondering about the leaf spots. Any idea what they are from? General advice on saving these plants?

    I am also brand new to GW forums, obviously, and am very excited to join the fun!

    Have you had any hailstones? - that's what it looks like to me.

    If you can post a pic of the whole plant that may help us diagnose the wilting problem

    Have you had a hailstorm by any chance, when the leaves were just opening? The ones that I grow (T. flavum glaucum and T. "Elin") don't seem to be particularly prone to any pests so I'm wondering if your marks could be physical damage.

    My advice is to water them really excessively about once a week - but then let them dry out a little bit unless they show serious signs of drooping. They're probably looking a bit unhappy because they've been moved to a new microclimate, possibly less sheltered than where they were before. They will acclimatise after a week or two and will be absolutely fine in the long term. 

    The spots are probably from watering during strong sunshine (creating droplets that catch the sun and burn the leaves like magnifying glasses). Very superficial damage but water in the evening or avoid splashing the leaves if you want to avoid it.

    No hail here. The weather has taken a quick turn to warm, humid, and windy. 

    The circled leaves are the ones that were completely droopy last night. Now they are a bit perkier but are dark and damaged in places. 

    It’s T. Rochebrunianum in case that’s useful.

    thanks for the welcome and the quick help!!

    Maybe heavy rain has damaged the ends of a few leaves? Looks healthy otherwise to me.
    They're tough plants despite their delicate look and they're generally pest and disease free.
    I've got quite a few around the garden and they self-seed a bitt too when I'm lucky

    Ok, I will try to calm myself then and take advice from @Loxley. I did water in a sunny moment and I'll bet you're right about the cause of the damage! 
    Anyone else get skittish and antsy when dealing with a new type of plant? 

    Thank you!

    Sometimes - if it was expensive or something special.
    But sometimes they just die because they're not happy in my garden - it's all learning.

    I've got some in quite deep shade and others that get plenty of sun, they all do well and I often find some seedlings around the base of the plants in spring.
    My oldest ones (about 12 yrs) happily survived the drought last year too without watering.

    ..this is Thalictrum rochebrunianum in my garden...

    Two things.. the wilting stems you notice occur on mine too, when the sun is out and strong.. not today as it's cold and cloudy.. this will right itself in time when the top part of the stems get stronger.. they give the look of lacking in water, but you can soak the ground and it will still wilt..  my  garden was flooded recently, so no shortage of moisture here at the moment, but this will droop again when the sun shines..
    ..don't worry about it..


    .. I don't have those spots on my leaves, but if you look on the undersides of the leaves, you may see little white grubby sawflies [tiny slug like creatures] that cause this issue.. they won't kill it, so no need to fret..
    If they are not there, then it's caused by something else..

    Thank you, everybody! I am much comforted by the information. And thanks, @Marlorena for sharing your picture!
