New garden - help me work out what's in here! (with pics)

[MunsteadWood]

Just moved house, garden a bit of a mess but west facing and sunny with lots of potential. Nice sunny south bed running along one side with a mix of shrubs, a few (heavily pruned) trees and a load of ground cover which is probably a mix of emerging perennial shoots and weeds.

I've gone round today trying to work out what's in the bed (lots of roses, an enormous rosemary, some old lavender, daffodils, pulmonarias, some box) but there a few I can't ID!

Can any of you wise MNers help? What have I got? I want to get weeding but am scared I'll accidentally chuck something lovely on the compost heap!

The geraniums - there's a lot going on in that picture.At the top, next to the celandine, there are geranium leaves, but I think of one of our native hardy geraniums, possibly G molle or G pyrennaicum. In the middle, to the left of the possible wallflower, you have what could be aquilegia - if so, it would have smooth greyish leaves, Centre bottom looks like Wood avens, Geum urbanum.

Thanks so much all for your thoughts. This is very helpful! I'm going to start digging out the celandine and 100s of dandelions this afternoon.

One last pic attached here. Does this look the same as the hypericum in the first picture? I'd assumed they were the same but not 100%.

And I've been doing a bit of googling about the trees and am thinking cherry or plum most likely. The bark is very smooth and shiny and a sort of greyish brown colour, which looks different to the pictures I've found of pear trees. @DobbyTheHouseElk what is the bark like on your damson?

Grrr picture won't post... will try again later

Cherry usually has sort of fine horizontal lines on the bark. Have you eliminated blackthorn?

This is the tree bark. All three look the same. Cherry?

And @MereDintofPandiculation I wondered about blackthorn as the flowers do look similar. But I can't see any thorns...

hypericum is not wildly exciting, but it flowers away all summer, is tough and can be chopped bakc etc. It is a useful shrub to have in a large garden

@MunsteadWood bark looks the same as damson. Also to the right is a curved branch, like my damson.

Do you like Damsons? I don’t personally like them, but I can’t bear to remove mine, so I give the fruit away to friends.

The blossom looks like Damson/Plum rather than Cherry, which has smaller anthers I think,
I think that the non flowering Daffs could well be Sisynchrium as someone upthread said, have a look on google. Their stems are much thinner, more like Irises than Daffs.
As a gardener of some 20 years and several gardens down the line, your best bet is not to rush and I suggest not moving anything just yet.
Take pics, keep a notebook, make some labels if that helps, or use canes to mark things you are unsure of.
Perhaps consider getting some paid help to start you off, someone who can do the idents in person and help with pruning/weeding etc.

I wondered about blackthorn as the flowers do look similar. But I can't see any thorns... doesn't necessarily have many thorns. Has very dark new twigs (hence "blackthorn") If you don't need to be rid of i, just wait to see what fruit you get. Trouble with Prunus is that the flowers are all very similar. Cherry plum and blackthorn are usually the first to flower.
