I like your crabapple tree. Do you eat them? I've never heard of oxeye, but I love perennial plants. I have low germination with pepper seeds, too. Sometimes I just give up entirely. The pitcher plant was what really caught my attention! You have to post more pictures later when they grow! Do you fill them with water? In the wild, small animals use them as toilets.
Every week when I went shopping, I used to buy a small flower mix like yours and scatter them. Now, it sustains itself. From experience, you'll need more than one packet but, yes, it does look like that.
