Primroses/Evening Primroses - Any and all help much appreciated

Hi Everyone

I am a new gardener and have some wild primroses and an evening primrose I'm trying to grow/not kill - I've had a go at looking up some info on them but it all seems contrary so I thought I would ask the experts. Apologies in advance if I come out with anything silly and please do have a giggle at me - I'm here to learn a new skill and if my muddling raises a giggle in others while doing so then that's a definite bonus lol.

They're all in patio planters with miracle-gro compost after being received via mail order. I have the wild primroses in what I think is dappled partial shade (they're under a small tree that gets full sun from dawn to around 2pm) and the evening primrose in partial sun (it gets full sun from dawn to about 13:30). Is this sensible or lunacy?

The wild ones appear to be okay so far (I read they were particularly difficult to kill so thought it a good one to start with) but the evening primrose is still looking a little sorry for itself - I think this may be due to my re-potting it twice since it arrived about three weeks ago (it got dug up by a nasty little brute of a squirrel and had a peanut buried in it so I moved it to a less rodent-strewn location) but wanted to be sure I had it in a good place now and that it should perk up with a little TLC and time, or if I'm setting it up to fail. Any suggestions on location/shade/watering would be very much appreciated

Kind Regards,
Emma

 

Right, for starters evening primrose is a totally different from the wild english primrose, perhaps that should be British primrose.
That is a woodland plant that likes cool damp conditions and is basically a spring flowering plant.

Evening primrose I believe I'm right in saying is an American plant and there are some different species, but most flower mid summer, and, believe it or not., late afternoon till early next morning.
It also gets tall, depending on the species, and in my experience it hate root disturbance.
Which might point out why its struggling a bit, but give it time.

 

Thank you very much Pete - I will leave them all where they are and give the evening variety some time to settle in. Thanks for clarifying what's what with primroses, I was getting lost
