Dear Zena you must be a clever old stick, and if your not you will be by the time you have finished all the courses.
As for the sinks i planted up, they were more of an alpine selection. I also planted up a very large, shallow circular tub with simular plants.
The plants consisted of a collection of Saxifages a collection of Sempervivums, creeping thymes, Dianthus erinaceus, Dianthus subacaulis?, Thrift, Phlox subulata, and a lovely little Limonium minutum, there were a few others but i can't think what they were at the moment. I know all these are not strictly alpines but they look rather gay together.
I used one part loam, one part leaf mould and one part pea shingle for planting them in.
Then top dressed with pea shingle when i had planted up.
Don't forget to put Pete in the bottom first, sorry i meant old crocks.
And there you have it job done.
Kind regards Old Herbaceous.
