Total beginner - new house - help! (Photo)

[museumum]

This is the southern edge of our new house garden. A beech hedge. The last 1.5-2m strip of sloping rockery is obviously in the shadow of the hedge a lot and quite bare of plants.
Any suggestions for what I could put there? (We're in Scotland so hardy please - and I love alpines but need something with decent cover not too dainty).

I get my snowdrops in the green from gee gee bulbs , in February . You can't get them now as they are dormant. I've never seen them in garden centres in the green , presumably because they are dug up from the field and sent out immediately to be planted within a few days . So a short life product .

Warning - 100 snow drops isn't a lot

Another warning - online bulb shopping is almost as addictive as Pinterest

Third warning - planting bulbs is backbreaking work

Thanks.
