I'm very fond of Geraniums (did I mention this before?). I tolerate them self seeding all over the place, and by being selective in my choice of species and varieties, as well as being a ruthless editor, I've managed to find a place for a large number of my favourites.
Of those favourites, the small 'rock garden' types such as G. cinereum and G. argenteum are the most difficult to place.To look their best they need lots of sunlight, and they can easily be overwhelmed by any larger plants surrounding them, and it was this in mind that several years ago I came up with the idea of making a trough large enough to hold a collection of the small Geraniums.
This is the Geranium trough newly minted.
I filled the bottom with crocks and rubble.
I added some gravel and placed rocks.
This is how it looked when it was first planted.
This is how it looks today, now moved to an even sunnier location.
Geranium x lindavicum 'Apple Blossom'.
Geranium cinereum 'Alice'.
I've also been able to grow the smaller Geraniums in the ground at the edge of a gravel pathway, here Geranium sessiliflorum ( with the dark brown foliage) self-seeds around and seems to thrive in the inhospitable location.
