may be found sometimes 

 tJfl. or 7 ft. high. In an 

 area of a house in Berke- 

 ley Street, there were, in 

 18;3(!, two plants, about 

 6 ft. high, and of propor- 

 portionalc bulk. Mr.

 the Plectrimthus fruti. 

 C0SU3 in green-houses, 

 as the most susceptible 

 of cold ; which, it pro- 

 perly placed, will prove 

 a warning thermometer 

 to guard against direct 

 injury to others, as it is 

 always the first to suffer, 

 and consc<iucntly will 

 show the increasing 

 harm. [Gaitl. Mag., vcl.

Zidcritis cnndicans 

 Ait., Com. Hort., 2. t. 

 99., is a native of Madei- 

 ra, an old inhabitant of 

 ; green-houses inEngland, 

 and of orangeries in 

 France, where we have 

 seen it growing about 

 the same; height as the 

 Plectranthus frutic6sus. 



There are several other sorts, from the Canaries, Spain, the Levant, &c., which will be found enume- 

 rated in the Ilortus Britannicus, all of which would probably live on rockwork, with very little pro. 

 tection during winter. 



Leonbtis Lcuiihrus B. Br. ; Phlbmis LeonOrus L., Bot. Mag., t. 4/8. ; is a Cape shrub, which has 

 been in the country since 1712. It grows to the height of 3 ft. or -Ift, and is tolerably hardy. It 

 bears showy scarlet flowers, but does not flower freely in Britain. 



Sp/idccle cnmpanulhta Benth., Bot. Reg., t. 1382, and our fig. 1151., is a 

 shrub, from Chili, which grows to the height of 2 ft. or 3 ft., and produces its 

 pale blue flowers in July and August. There is a plant in the Horticultural 

 Society's Garden„which has stood out at the foot of a wall since 1832. S. 

 Lindliy\ Bcnth., Bot. Reg., t. 1226., is another species which was introduced 

 from Valparaiso in 1825. 



DracociphaIu7n cnnaridnse Com. Hort., 2. t. 41., is 

 an old favourite, much esteemed for its fragrance. 

 Trained against a wall, and protected during winter, 

 it will, in two years, cover a space 4 ft. or 5 ft. high, 

 and 5 ft. or 6 ft. broad ; producing its pale purplish 

 flowers in abundance from July to September. It 

 may be raised from seeds early in spring, and turned 

 out in the borders, like a tender annual. 



Salvia sitlind<-ns Ker, Bot. Rog., t. &87. ; S./o>-7>wsa 

 Willd., Bot. Mag., 375. ; S. fiiigcns Cav., BoL Reg., 

 1356. ; and S.Grahanii Bnilh., Bot. Reg., t. 1.370., and 

 our^g.1151. ; arc all splendid suflTruticose plants, na- 

 tives of South America, which will live through the 

 winter against a wall, and flower beautifully during 

 summer ; but, though technically shrubs, in prac- 

 tice they are best treated as herbaceous plants, kept 

 in pots and pits, or green-houses, through the winter, 

 and turned out into the open borders in spring. 

 S. Grihami has stood in our garden, in the open 

 border, through the severe winter of 18.!.')-.36, without 

 any protection whatever. S. chamtrdryii'ides Cav. is 

 a dwarf species, the flowers of which are of a jiccu- 

 liarly intense and brilliant blue. It is frequently grown in England for planting out in bctis in regular 

 flower-gardens, where its flowers form a mass of beautiful blue. There are some Cape species, which 

 are truly ligneous, that might be tried against a wall. Of these, S. afirea is one of the most splendid. 

 Vrtisium viAjus L., Fl. Gra?c., t. .'584., is a native of Spain, which has been in the country since the 

 time of Gerard. It grows 3 ft. nigh, and produces its white-spotted flowers, some of which are fol- 

 loxvcd by pulp-covered seeds, from June to August. , „, , , . , , 



Prostanthira lasi&nthos Lab., Bot. Reg., t. 14;3., is a native of New South Wales, which has stood 

 in the Horticultural Society's Garden, at the foot of a wall, since 1831 ; but it was killed in the spring 



Other half-hardy Snccu'S belonging to this order may be found in considerable numbers by looking 

 over the lists in oiir Hortfs Britannicus; but, with the exception of the salvias, the phlomises, and 

 the lavandulas, we can hardly recommend any of them for culture, except in the warmer situations 

 of the south of England, where thev will ftiow with little or no protection. Where much labour 

 and cxi>onse are retpiired to protect tender plants during winter, only those that are truly ligneous 

 ought to be made choice of; but where the climate is such as to render protection easy, a greater 

 latitude may be nllowed.
