Nemophila - how fussy?

I have a packet of Nemophila seeds, bought on a whim (isn't it amazing how big your garden is in your head? ) - anyway, I have no idea where I am going to put them.

At the end of my patio, there is a small wall that has a border in it, and just in front of the wall (patio side), there is a small strip of soil in the gap between the slabs and the wall. Last year, I grew wee flowers in there (can't remember the name, but they look a bit like alyssum), so I know that it can support some sort of life - thing is, I don't know how fussy the nemophila are about positioning and soil quality?

 

I surely can't be the only one Fern - in my head, my garden must be huge, as I keep buying seeds and plants! I think its bigger in the winter time too, coz I seem to accrue a lot of stuff over the winter in readiness.......

 

In my garden they grow a bit like weeds, self seeding for the last couple of years. They are very tough little plants and don't seem to mind my poor soil so go for it fc

 

Thanks again John - I found growing those other things last year that it really took the edge off the patio, so hopefully they will look just as good.
