Another shot of my Moon Garden at dusk, from early June, 2007.
After I labeled the Nemesia, I found some notes to the effect that this was Nemesia 'Vanilla Sachet'. (I couldn't figure out how to edit the tag, and I didn't want to start all over.)
The low growing variegated mound in the lower right of the image may have been an Arabidopsis. (It is no longer present in the garden.)
