Arctostaphylos 



Arenaria 



The most suitable position for arches is where 

 they span broad grass or gravel walks, but it is 

 uasv to have too many o them, more especially 

 in the case of small gardens. A pergola is really 

 an extended series of connected arches. (.See also 

 PTOGOLA). 



ARCTOSTAPHYLOS. 



Hardy or half-hardy shrubs (aril. Ericaceae), re- 

 moved from Arbutus by the live-celled fruits and the 

 one-seeded cells. They are propagated by seeds, 

 sown in sand and peat in a cold frame in March ; 

 by budding, and by inarching. For soil, take 

 loam and peat in equal parts with sand ; or peat 

 and sand. No lime. 



Principal Species : 



alpina, the Black Ber.rberry. A trailing, de- 

 ciduous shr. Ap., vvh. or pk. (.<#. Arbutus 

 alpina).

ARCTOTHECA. 



Greenhouse herbaceous perennials (ord. Com- 

 posite) allied to Arctotis. They succeed in peat, 

 leaf mould, and loam in equal parts ; and may be 

 propagated by root division and by cuttings in the 

 spring. 



Principal Species : 



rcpcns, Jy., yel. 



ARCTOTIS. 



Handsome, half-hardy, herbaceous perennials 

 (ord. Composita;) for dry, sunny places in beds 

 or borders, or for pots in cool greenhouses. Soil, 

 loam and leaf mould. The flowers ail: large and 

 Daisy-like. They are propagated by seeds sown in 

 heat in spring, or by cuttings placed in pots in a 

 little heat at any season. 



Principal Species : 



acaulis, l.V, Je., red, yel. 



aspera, 2J to 3', Jy., yel., a fine plant.

 cuprea).

ARDISIA. 



Description. Evergreen stove and greenhouse 

 shrubs (aril. Myrsinea;), with rather small flowers, 

 but bright, showy berries. 



Propagation. (1) By cuttings. Half-ripened 

 side shoots taken during the summer months strike 

 quickly in a bri.-k heat. (2) By seeds. The finest. 

 and ripest berries should be sown in spring in well 

 drained pans filled with a compost of equal parts 

 of loam and peat, with sand, and plunged in 

 bottom heat. 



Soil. Two-thirds good loam, one-third peat or 

 leaf soil, with enough sand to keep the compost 

 open. 



Other Cultural Points. Ardisia crenata is the 

 one best known, ami the most, useful. It delights 

 in a fair amount of heat, 50 to 55 or 00 during 



winter, and 00 to 75 in summer ; and in plenty of 

 moisture, both at the roots and overhead. Young 

 single-stemmed plants in 0" pots make the best 

 specimens, as in this size they are very useful as 

 table plants or for general decorative work. Firm 

 potting is essential to ensure short-jointed, stubby 

 growth. Old plants may be cut back in the 

 spring, and if water is withheld until the cuts have 

 healed the plants bleed freely otherwise they 

 will soon break into fresh growth, and may then be 

 potted up. Scale and mealy bug are great pests, 

 and the foliage and berries soon collect soot and 

 particles of dust from the atmosphere. The con- 

 stant use of the syringe, and the occasional em- 

 ployment of the sponge, are advisable. Weak 

 soapy water makes a capital wash. 



Principal Species : 



crenata (sym. crenulata and crispa), 3' to 4', Je., 

 flowers red vio., berries bright coral red, hanging on 

 for a long time. There is a white-berried var.

ARECA. 



Stove Palms (ord. Palma;). A number of species- 

 formerly included under Areca are now referred 

 to Acanthophrenix, Euterpe, Hyophorbe, Kentia, 

 Oncosperma, Ptychosperma, and Chrysalidocarpus. 

 They are propagated by seeds. Peat or .leaf soil 

 and loam in equal parts for the young plants, all 

 loam, with sand, for the older, suit. 



Principal Species : 



Catechu, the Betel Nut Palm, 30', leaves 3' to G' 

 long. 



lutescens, the popular market I'alm, now referred 

 to the genus Chrysalidocarpus. 



Other Species : 



Alicia?. glandiformis, 30'. 



conciuna, 8' to 10'. triandra, 20'. 



ARENARIA. (SANDWORT.) 



A large genus of dwarf, hardy plants (ord. 

 Caryophyllese), comparatively few of which are 

 worth growing; but some of the perennials are 

 valued for rock gardening or for carpeting. They 

 have generally narrow leaves and small white 

 flowers. Grandiflora and montana are suitable for 

 the front of borders, or for growing in pots in a 

 cold house or frame. Propagated by division, seeds, 

 or cuttings struck under glass. Loam, sand, and 

 leaf mould are suitable. Plant in sunny, exposed 

 positions in dry soil, except in the case of 

 balearica, which thrives in a damp place. 



Principal Species : - 



balearica, 2", Men., wh. A charming little creeping 

 plant, with very small flowers. 



grandiflora, 0", Je., wh. A handsome Alpine, 

 with large flowers. 



montana, 3", Ap., wh. Earlier than the pre- 

 ceding species. Flowers about equal in size. 



purpurascens, 0", My., pur. A neat plant, 

 especially desirable because of its distinct colour. 



Arduina (see Carissa).
