    Last winter was unusual, in that it was fairly harsh, and followed a very hot, dry summer. A lot of plants suffered.

    And the first cold snap was early, colder than normal and hot on the heels of a wet spell so anything other than a free-draining soil would have been soaking wet then frozen solid, which is exactly what many not-fully-hardy plants dislike most.

  • Hi i want to replace the bush but am concerned as you say it isnt pontelllia it was purchased over a decade ago from the Southport flower show and was labelled pontellia also the shrub you all name you all state isnt hardy this shrub is over a decade old and has grown from strength to strength every year through winter with no issues until this spring needing pruning to keep in the space we want it to grow in. You also state pea shaped flowers this bush has open buttercup like yellow flowers. Unfortunately i have and am having a huge photo clear out so haven’t got any of the very old photos of this the earliest is 2019 but it’s over 10 years old the one of the full lawn with dogs toy on. I have added more photos with the original dates taken showing on the photos. Also the photo of the pruned ready for winter garden was taken oct 2022. I have taken a close up of the leaves too. Can you all have a better look and imagine with open yellow buttercup ish open yellow flower. It has survived at least ten winters and hasn’t been treated any different to any other year. fairy girl All the other plants in the bed are thriving as you can see in the photos dated recently. As was the bush in October when the healthy photo was taken come spring it was brown however as i stated when cut the inside is green. Thanks
  •  Please see above question as you need to read it for photos to make sense they wouldn’t attach

    With a buttercup-like flower it probably is (or rather, was) a potentilla. Mine has paler more primrose-yellow flowers and greener foliage, whereas yours looks blue-grey-green like the coronilla that I had. Available varieties of most plants can change over time with older ones going out of cultivation as newer ones are introduced, so you might not be able to get the exact same thing.
    Potentilla is properly hardy here, but it could still be the combination of hot dry summer causing stress, followed by wet then cold, that killed yours. Plants don't live forever, although 1- years doesn't seem long for a shrub so I doubt it was just old age.
    You also mentioned "soil amendment 12". Is that a plan or something you already did? If you piled up more soil/compost around it, touching the bark, that could have been a factor (roses don't mind that treatment but it's not good for many trees and shrubs).

  • No its green foliage not at all blue grey. Meant the shape buttercup not colour it was just yellow flowers cant put a shade on it not bright bright but not pale yellow. My gardener said a lot of people have lost theirs this year along with New Zealand flax our flax had a lot of dead leaves but once they where removed it was fine but saying that it must be 40 years old.a plan 6 inches of compost then mulch not 12” sorry dont know why i put 12” no it will be 12” from the plants maybe thats where the 12” came from lol and no not piled up. So you think i should remove it even though the cuts showed green fresh bark Thanks so much 
  • Jenny j the reason for the soil amendment is due to not doing the usual few inches during Covid

    Photos and screens can be misleading for colours (that's my excuse and I'm sticking to it!). 
    I think if it was going to re-grow it would be showing signs by now. If I were you I'd be looking in local nurseries and garden centres to see what's available, with a view to getting a replacement for autumn planting.

  • Thanks Jenny j a lot are older photos iphone cameras have come a long way in a decade also light/sun makes a difference i would say the leaves are not much lighter than a healthy roses leaves. I just wanted a definitive answer which you’ve given me as you can imagine it’s costing a fortune to do the soil amendment as our garden is huge and at present over 200 plants in it. As well as the soil amendments i am planning at least twenty new plants to go in the back beds very near the bush so obviously dont want to have to dig and ruin the soil amendments and disturb the new plantings just after doing. That’s why I wanted a definitive answer so i can get it out before. Gill our gardeners coming on Thursday so she’s going to have another look but as soon as she started back in the spring her first words where oh no you've lost your pontellia too but she was hoping if i chopped it and treated it it may resurface but no joy. So thanks so much for the definitive answer i really appreciate it x

    Here's a link with just about every Potentilla there is. Any without a photo could be searched on other nurseries online using the name

    I still don't think that plant you have was a potentilla. The foliage is wrong. I doubt that anyone has lost them over winter either. You'd have to be somewhere much colder than the UK for them to have died. Even the small ones are very tough.
    Are you somewhere else and not in the UK?  They are very very hardy shrubs in this country.  :)
    It's a place where beautiful isn't enough of a word....



    I live in west central Scotland - not where that photo is...
