CERASTIUM. (MOUSE-EAK CHICKWEED.) 



A large genus of dwarf plants (ord. Caryophylleie), 

 many of which are mere weeds, but a few of which 

 are o'f considerable value for edg- 

 ings, rockwork, or walls because 

 of their pretty white flowers 

 and silvery or grey leaves. Only 

 the best are named below. Pro- 

 pagation is by seeds sown in 

 spring in a frame or in the open 

 ground, by cuttings under a hand- 

 light in spring, or by division 

 of large plants. A light, sandy 

 soil is the most suitable.although 

 they can be grown in common 

 soil. Young plants ought to be 

 carefully protected from slugs, 

 which are very fond of them. 



Principal Species: 



alpinum, 4", Je., wh. A pretty 

 native species. 



Biebersteinii, 6", My., Je., wh. 

 This and tomentosum are among 

 the very best for the garden. 

 Flowers large, Ivs. quite wh. 



Boissieri, 9", Je., wh., silvery 

 Ivs. and good sized flowers. 



grandiflorum, 6", Jy., wh. 

 Mather coarser,and only adapted 

 for trailing over rockwork. 



tomentosum, 6", My., etc., wh. 

 The best known, largely grown 

 for its wh. foliage and flowers. 



CERASUS. (CHERRY.) 



The Cherries (ord. Rosacea;) 

 are now included by modern 

 botanists with Primus, but are so 

 generally known in gardens as 

 Cerasusthat it is moreconvenient 

 to deal with them under this 

 name. The varieties of the fruit- 

 ing Cherry will be found under 

 CHERRY. The greater number of 

 those now referred to are hand- 

 some trees or shrubs suitable for 

 the garden or for decorative 

 planting. The double-flowered 

 Cherries are very beautiful. Pro- Photo: C. R. sick. 

 pagated by seeds sown in beds in CEKASUS 



autumn or spring, by cuttings in 

 autumn or early winter,and by grafting and budding. 

 Any good, rather sandy soil. Some of the smaller 

 Cherries are very suitable for forcing in gentle heat. 

 The double Pseudo-cerasus, also known as Watereri 

 and Sieboldii rubra,is one of the best for this purpose. 



Principal Species and Varieties : - 



Avium, the Wild Cherry or Gean, 40', Ap., My. 

 There are several valuable forms of this, that called 

 flnre pleno or multiplex having double flowers ; 

 Juliana, blush ones; pendula, a drooping habit; 

 and laciniatn, cut Ivs. (syns. domestica, dulcis, 

 nigra, and sylvestris, correctly Primus Avium). 



Cerasus, the Common Cherry, 20', Ap , wh. There 

 are several vars. of much beauty, that called Rhexii 



Ceradia (see Othoiina). 



11. pi. (ayin. caproniana multiplex, ranunculiflora, 

 etc.) being very fine (correctly Primus Cerasus). 



Laurocerasus, the common Laurel, 10', Ap., wh. 

 A favourite ev. shr., the following being among 

 the best of its forms: rotundifolia, caucasica, 

 colchica (free-blooming), and latit'olia. The var. 

 schipkaensis is very hdy. (correctly Prunus Lauro 

 cerasus). 



(CORRECTLY PRUNUS) AVIUM PEXDULA. 



lusitanica, the Portugal Laurel, 20', Je., wh. 

 Another well known ev. shr , and one much 

 admired when in bloom. Myrti folia is a pretty 

 form, with smaller Ivs. (correctly Prunus lusitaniofc). 



Mahaleb, 10', Apl., wh. This and its silver- 

 variegated form, variegata, are worth growing 

 (correctly Prunus Mahaleb). 



Padus, the Bird Cherry, 12' to 30', Ap., wh. The 

 forms of this are rather numerous, but argentea 

 and rubra are both good (correctly Prunus Padus). 



Pseudo-cerasus, Iff, Ap., wh. or blush. This is 

 useful for forcing, and beautiful in the garden 

 as well (si/us. Sieboldii rubra and Watereri, cor- 

 rectly Primus Pseudo-cerasus). 



serrulata, 12', Ap., ro. or wh. Handsome double 

 flowers (correctly Prunus serrulata)
