This beautiful little plant is too tender to be trusted out in our climate in most parts of the country during winter; but it is such an essential gem that it should be included in every collection of any pretensions, where a dry cold frame can be afforded it when it wants protection. I have seen it survive mild winters in the neighbourhood of London; but it was late in being stirred into growth, and weakly throughout the season, and flowered unsatisfactorily. There is no doubt but that it would be much more comfortable and successful left out in some of the more southern and western parts of England, and the more favoured localities of Ireland; but there is little hope for its safety if left out in Scotland. It has quite the habit and appearance of some of the smaller alpine Violets, extends itself by weak trailing branches rooting as they advance, has small bright-green kidney-shaped leaves, and the flower-stalks only 2 or 3 inches high, bearing the small delicate blue-and-white flowers in moderate profusion and long continuance.
It is a charming little pot plant cultivated in the same way as pot alpine plants, and may be used with good effect in light airy greenhouses; but its best use will be found in edging and carpeting small beds in warm positions in the flower-garden. In the north it may not succeed so well in this way as in the south, but in warm terrace-gardens it may succeed in any part of the country; and it is so easily propagated by division and cuttings that it should be tried out of doors everywhere, for though not very striking, it is sure to arrest the attention of all who may pass it who are fond of simple beauty and freshness. In cold localities the plants would be best plunged in their pots instead of planted out. Native of Australia.
