colour, flowering in July, which is always valuable. G. 

 cmruleus is a beautiful dark-blue colour; it flowers 

 earlier, and is not so hardy. Gercis, or common Judas 

 Tree, and Buddleia globosa both look well on walls where 

 there is room, Vitis coigneticB is a very handsome rapid 

 grower, and covers quickly a barn, a roof, or a dead tree. 

 The claret-coloured Vine, with its Uttle bunches of black 

 grapes, is very eS'ective. The grapes are used in Prance 

 and Germany for darkening the colour of wine. AbeUa 

 rupestris, a lovely little, rather tender shrub, would grow 

 admirably against low greenhouse walls. Why are such 

 spots generally left quite empty by gardeners in large 

 places? The single white McCartney Eose would do 

 well in a similar situation, and for those who are in the 

 country in June it is well worth a place. AvmSe Vibert, 

 Gloire des Bosemaines, and Fallenberg are delightful Boses 

 for house or pergola. Sweet Verbena {Aloysia citriodora) — 

 Why, oh ! why, is this little shrub, which everyone is so 

 fond of, grown so little out of doors ? Practically, with a 

 little care, its roots are quite hardy, as in the very severe 

 winter of two years ago only one of mine, out of five or 

 six plants, was kiUed. It requires nothing but planting 

 out late in May, watering, and not picking at first, as the 

 growth of the shoots makes the roots grow. It may be 

 picked in early autumn as much as you like, but the 

 summer growth should not be cut down to the ground 

 tin the following spring. It is the easiest plant possible 

 to strike in spring, and there should be plants of it 

 planted in greenhouses, others grown in pots, and brought 

 on in stoves in spring; but nearly all gardeners are satisfied 

 with one Uttle plant of it in a pot, unless they are urged 

 to increase it. Mock Orange {PMladelphus granddflorus) 

 looks very well against a warm wall in July, but shoidd 

 not be nailed in too tight. Piptanthus nepalemis on a 

 warm wall is admirable, but rare ; I have only seen it once.
