may be found sometimes 



f> ft. or 7 ft. high. In an j 14,9 



area of a house in Berke- 

 ley Street, there were, in 



1836, two plants, about 



6 ft. high, and of propor- 



portionate bulk. Mr. 



Bowie, in a very interest- 

 ing communication to 



the Card. Mag. on raising 



Australian and Cape 



shrubs from seeds, and 



acclimatising them to 



Europe, proposes to place 



the Plectranthus fruti- 



cosus in green-houses, 



as the most susceptible 



of cold ; which, if pro- 

 perly placed, will prove 



a warning thermometer 



to guard against direct 



injury to others, as it is 



always the h'rst to suffer, 



and consequently will 



show the increasing 



harm. (Gard. Mag., vol. 



viii. p. 7.) 



Siderltis cdndicans 



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 fruticbsus. 



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

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

 tection during winter. 



Leonbtfs Leonitrus R. Br. ; Phlbmis Leonurus L., Sot. Mag., t. 478. ; is a Cape shrub, which has 

 been in the country since 1712. It grows to the height of 3 ft. or 4 ft., and is tolerably hardy. It 

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

 Sphucele campanulata 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 %v 



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. 

 Lindltyi Benth., Bot. Reg., t. 1226., is another species which was introduced 

 from Valparaiso in 1825. 



Dracocdphalum canaritnse 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.

 tives of South America, which will live through the 

 winter against a wall, and flower beautifully during 

 summer j 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,

 any protection whatever. S. Ghatrufdryoldet Cav. 5s 

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



and turned out into the open borders in spring. 

 S. Graham/ has stood in our garden, in the open 

 border, through the severe winter of 1835-36, without 

 protection whatever. S. Ghatrufdryoldet Cav. i 

 arf species, the flowers of which are of a pecu 



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

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

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



Prasmm mdjtis L., Fl. Grace., t. 584., is a native of Spain, which has been in the country since the 

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

 lowed by pulp-covered seeds, from June to August. 



Prostanthlra lasidnthos Lab., Bot. Reg., 1. 143., 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 

 of 1836. 



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

 over the lists in our Horlus 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 they will grow with little or no protection. Where much labour 

 and expense are required 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 allowed.
