In My Garden I see that an expert on rock

gardens (incidentally a term that some experts dislike) complains of the white violet as a weed. With me it certainly multiplies inordinately, but happily in welcome places, and the more precious sulphurea has something of the same gift. It is worth while, as I have seen, to keep a place solely for violets to extend them- selves. Loveliest perhaps of the rock weeds is a speedwell, sometimes called the New Zealand Veronica, but it does little direct harm and is a good carpet for bulbs. The best of the rock tresses, or aubrietias, is given. as Guredyke, with Magnificent as a good second.
