HARDY SHRUBS IN GREENHOUSE 281 



in pots 7 or 8 inches across and plunged in the 

 open ground. This treatment results in close and 

 compact balls of soil, which, when turned out of the 

 pots, retain their shape and bear the journey well. 

 These plants are pruned hard back after flowering 

 to keep them dwarf. Lilacs that have been frequently 

 moved may be lifted and flowered without risk. Most 

 of those sent from Holland consist of the white- 

 flowered variety, Marie Legrange, but the dark-coloured 

 Charles X. is also grown. The many double-flowered 

 Lilacs are not so popular as the singles. It is a pure 

 delight to smell the flowers of the Lilac long before 

 they appear in the open garden ; they are most 

 welcome. 



VIBURNUM. When the plants are well budded the 

 Laurustinus (V. Tinus) will flower throughout the 

 winter in a greenhouse. Of those that are amenable 

 to slight forcing the best are the common Guelder 

 Rose ( V. Opulus sterile), the Chinese V. plicatum, and 

 V. macrocephalum. Treat them in the same way as 

 the Lilac. The Guelder Rose is a delightful shrub 

 under glass, with its wealth of ivory-white balls. 

 It is one of the most interesting of all the things that 

 can be brought into bloom in a greenhouse. Treat 

 the Viburnums in the same way as recommended for 

 the Lilacs. 



WISTARIA. It is only within the past few years 

 that the Wistaria has been used to any extent for 

 flowering in this way, but now it is universally 

 admired. At the exhibitions early in the year it 

 always attracts more attention than any other shrub
