Help is needed here

Hello Friends.

I have attached 2 pictures of my small garden place ... i tried to made something puffy and nice .. but all died .. and its half part shade.
I really would love to get help from you.
Than i will pass my new obtained information to my son ))

My questions are :
What can i plant here so it will smell good and will look puffy and nice ...

What else would you advice, i will take every bit of help.
Thabk you all in advance.

I recommend hostas. There are tons of varieties and grow well in full shade.

Perhaps you could start by cleaning up all the stuff that you've got laying around all over, including the white rocks that offer nothing to the growing plants.  All those little pots and fencing and knick knacks and such . . . start with bare soil or perhaps a little layer of organic mulch (wood chips, compost, or something else that will feed your soil as it breaks down.

Then get one comfrey root and plant it halfway between the tree trunk and the outside fence.

Done.  Puffy, and light and good for your soil.
