GARDEN FLOWERS. 33 



The perennials are increased by division and seeds ; the bi- 

 ennials and annuals by seed. As they transplant badly, 

 they should be sown where they are to bloom. 



The flowers of most of the species of which there 

 are more than thirty are blue ; but A. angustifolia, lep- 

 tophylla, petiolata, and undulata, have purple flowers ; A. 

 incarnccta has flesh-colored, and A. ochroleuca and its vari- 

 eties, have yellowish-white ; A. myosotiflora has pink flowers. 

 A. Capensis and pulchella require greenhouse protection. 

 The following are good species : 



A aggregata (cluster-flowered) ; hardy annual ; flowers blue, 

 in June ; Levant; 1827. A. amcena (pleasing) ; hardy annual; 

 flowers blue, in June ; south of Europe; 1817. A. Barrelieri 

 (Barrelier's) ; hardy perennial ; 2 feet ; flowers blue, in May ; 

 south of Europe ; 1820. A. Capensis (Cape) ; greenhouse bi- 

 ennial ; 6 inches ; flowers blue, in July ; Cape of Good Hope ; 

 1800. A. Milleri (Miller's) ; hardy annual ; 1 8 inches ; flowers 

 pink, in June ; Levant 51713. A. ochroleuca (yellowish) ; hardy 

 perennial ; 2 feet ; flowers pale-yellow, in July ; Mount Cauca- 

 sus ; 1810. A. paniculata (panicled) ; hardy perennial ; 3. feet ; 

 flowers blue, in June; Madeira; 1777. A. tinctoria (alkanet); 

 hardy biennial, or perennial ; 1 8 inches ; flowers purple, in June ; 

 Montpelier ; 1596. 



ANDROMEDA. [Ericaceae.] Beautiful evergreen shrubs, 

 principally hardy, but a few requiring a greenhouse or stove. 

 Soil, good rich moist peat, or peat with a third part loam. 

 They are best propagated from layers, put down in Septem- 

 ber, and taken off the following autumn. The seeds are 

 very small, and require to be sown as soon as ripe, very 

 lightly covered, and set in a cool close frame; but this is 

 too tedious a process, except with very rare kinds. Perhaps 

 A.floribunda maybe set down as one of the most useful of 

 all dwarf shrubs ; for it looks well from the time the bloom-
