Plants grown in pots lead naturally to the consideration of those most suitable for tubs. Of these the most important are permanent things of shrubby nature� several of the Orange and Lemon family, Oleander, Pomegranate, Bay, Myrtle, Datura, Sweet Verbena {Lippia citriodora} and dwarf Palm, also Hydrangea, Tree Heliotrope and Agapanthus. The last is of course a bulbous plant, but from its large, solid foliage and quantity of long-enduring bloom it is one of the best of plants for tubs. The greater number of these need housing in winter in an Orangery or other frost-proof building. Other bushy plants for tub use that are hardier are some of the Veronicas, such as Traversi, speciosa and hulkeana, Olearia Haastii and O. Gunni. Tree Peonies, though rarely so used, are capital tub plants, and, though they are not very long in flower, their supreme beauty makes them desirable. They should certainly be grown in places where labour is not restricted and where there are suitable places for standing such plants away and caring for them in the off season
