Convallaria

Copaifera 



get rid of any lurking insect pests, which should 

 never be tolerated in a conservatory. This clean- 

 ing and fumigating should be carried out when 

 the residence is temporarily unoccupied, as, how- 

 ever carefully performed, the fumes have a nasty 

 way of finding out places where their presence is 

 not desirable. 



Though conservatories should tend to preserve 

 plant life, many are built more with an eye to orna- 

 ment than utility, and are death traps for plants. 

 In building, see that all is done that is possible 

 to ensure the inmates keeping in good health for 

 a reasonable time. 



"\Vlinre possible, the structure should face the 

 south-east, as it then catches the early morning 

 sun in winter, and in summer becomes compara- 

 tively cool and shady by the afternoon the time 

 when it is in most request by its owners. Plenty 

 of ventilators should be provided at the top and 

 sides, opening on as many different aspects as 

 possible, so that air, which is essential to the 

 plants' well-being, can always be given, no matter 

 from what quarter the wind is blowing. Where 

 possible, roller blinds for shading should be fitted ; 

 but in cases where the shape of the structure 

 prevents their use, a wash of shading should be 

 painted on the sunniest portion of the glass. 



Climbers such as Oestrum elegans, Fuchsias, 

 Solanum jasminoides, Tacsonias, Passifloras, Plum- 

 bago capensis, Lapageria rosea, and climbing 

 Roses may be trained up the back walls and 

 over the roof ; beds may be formed and planted 

 with Camellias, Tree Ferns, Palms, etc., or pot 

 plants may be plunged in them ; while large 

 tubs containing Agapanthus umbellatus, Clivias, 

 Marguerites, Lemon-scented Verbena, Oranges, or 

 Myrtles are very desirable. 



CONVALLARIA. (LILY OP THE 

 VALLEY.) 



(Ord. LiliaceEe.) The chief plant belonging 

 to the genus is ruajalis, the favourite Lily of 

 the Valley, known to everyone, of which there 

 are several varieties, including proliricans, very 

 tall and robust ; flore pleno, with double flowers ; 

 and rubra or rosea, with pink blooms. (For details, 

 see LILY OF THE VALLEY.) Other plants called 

 erroneously Convallaria will be found under MAIAN- 

 , SMILACINA, and POLYGONATUM. 



CONVOLVULUS. (BINDWEED.) 



Description. A genus (ord. Convolvulaceac) con- 

 taining plants of much beauty, as well as some of 

 little value. There is much variety of habit among 

 them, some being twining plants suitable for 

 covering trellises, pillars, etc., while others are 

 erect-growing, and some are of shrubby habit. As 

 there are a very large number of recognised species, 

 it is impossible to enumerate them all, and those 

 which follow may be considered the best of the re- 

 spective classes at present available. The plant 

 known as C. major is Ipomcea purpurea. 



Propagation. The hardy perennials by division 

 of the roots in spring, by seeds sown at the same 

 season, and by cuttings of young growths ; the 

 annuals by seeds sown in spring; and the tender 

 species by cuttings, rooted in heat under glass, or 

 by seeds. 



Soil. The annuals and perennials will grow in 

 any. common soil, though they often prefer one 

 lightened with leaf soil and sand. The tender 

 ones like a compost of loam, leaf mould, and peat, 

 with a dash of sharp sand. 



Other Cultural Points. Great care must be 

 exercised in planting the hardy perennial species, 

 which usually run badly at the roots, to prevent 

 them from encroaching on other plants and taking 

 possession of too much space. It may be neces- 

 sary to confine the roots with stones or cement.
