large cordate or pear-shaped leaves. Some 

 varieties, such as Aristolochia sipho are 

 hardy and require no protection, but others 

 are only suitable for the greenhouse, for 

 which they form good pillar plants. The 

 climbers are propagated by division of the 

 roots and by layers, in spring and autumn ; 

 and the herbaceous perennials also by 

 division of the roots. These plants pre- 

 fer a good sandy loam, but peat and loam 

 must be used for the greenhouse varieties. 



Armeria, Sea Pink, or Thrift 



(nat. ord. Plumbaginacese). 

 Hardy herbaceous perennials propagated 

 by division of the plant. Formerly it was 

 much used for edging borders. Armeria 

 vulgaris, with rush-like foliage and red 

 flowers, is the crimson thrift of the garden. 

 A. litoralis and A. maritima are found by 

 the sea side. A sandy loam is the most 

 suitable soil for this plant. 



Artichoke, Globe (Cynara Scolymus). 



A plant that is grown wholly and solely 

 for its flower heads, which are eaten before 

 they come into bloom. There are two

tinguished as the Green and the Purple. 

 It is best propagated by offsets taken in 

 March. The plants bear best the second 

 or third year after planting ; so that it is 

 advisable to plant one or more rows every 

 year, and remove the same quantity of old 



roots. The ground should be deeply 

 worked and well manured : let the manure 

 be incorporated with the soil, not laid in a 

 mass at the bottom of each trench. It is 

 better to trench the ground first, and fork 

 the manure well into the surface-spit, which 

 gives the plants a better chance of im- 

 mediately profiting by it. The offsets may 

 be dissevered with a knife, or slipped off 

 and cut smooth afterwards, and planted with

a dibber. Some plant in threes, a yard 

 apart, and 4 feet from row to row ; or they 

 may be planted singly, 2 feet apart in the 

 row, and from 3 to 4 feet from row to row. 

 They should be well watered, and the 

 ground kept loose between. 



Salt, when used as a manure, is beneficial 

 for globe artichokes. If grown on stiff land 

 the soil should be lightened by plentiful 

 dressings of sand or road grit. 



Artichoke, Jerusalem (Heiiantims 



tuberosus). 



This is a hardy and profitable vegetable, 

 excellent for culinary purposes, and re- 

 quiring no protection in winter. It likes 

 a light, rich soil, and the ground should be 

 well dug over, and if at all heavy or poor 

 should be lightened by incorporating some 

 sand with it and enriched with well-rotted 

 manure. For planting, small tubers should 

 be chosen, and, indeed, reserved for this 

 purpose when the crop is taken up. These 

 should be set in rows, 3 feet apart, and at 

 a distance of I foot from each other in the 

 rows; they should, moreover, be set 6 

 inches deep. The ground should be kept
