HYOSCYAMUS. (HENBANE.) 



A .small genus (ord. .SoUinaeeas), and of no value 

 iiorticultmally. AH the plants in it are herbs, 

 biennial or perennial, and most of them have 

 poisonous properties. Niger, the Henbane, a native 

 of Britain, is used medicinally, and in the Middle 

 Ages was one of the witch's herbs. Propagation, 

 by seeds and root division. Light, rich soil is bi'.si. 



Principal Species :

 ol'u.'ii found on rubbish heaps and waste ground.

HYOSPATHE. 



Stove Palms (ord. PalmaV) with slender stems of 

 Heed-like appearance, and small, green flowers. 

 Propagation, by imported seeds. Soil, good loam 

 two parts, rotted cow manure one part, and one- 

 eighth of the whole grit. 



Principal Species : 



rlrgans, Ivs. 3' to 4' long; used for thatching. 



HYPECOUM. 



Hardy annual herbs (ord. Papaveracese), of which 

 only one species, procumbens, is at all frequently 

 cultivated. Propagation, by seed, which may be 

 sown outdoors at the beginning of April, for 

 flowering the following summer. For blooming in 

 spring, sow in the previous autumn. Any ordinary 

 garden soil will do, but a sunny position is best. 



Principal Species: 



procumbens, 1', spr., sum., hdy., yel. 



HYPERICUM. (ST. JOHN'S WORT.) 



Description. A showy and attractive genus 

 of perennial, herbaceous, sub-shrubby, or shrubby 

 nature (ord. Hypericinea;), to which have been 

 attached several interesting legendary associations. 

 There are said to be upwards of 170 species, so that 

 only a portion of them can be named. Some are 

 suitable for the shrublnjry and border, while the 

 dwarfer forms are charming plants for rockwork. 

 The flowers of all the Hypericums are yellow. 



Propagation. The shrubs, and a number of the 

 others, can be propagated by cuttings, removed in 

 spring or summer, and struck in light, sandy soil 

 in a greenhouse or frame, or under a hand-light. 

 The herbaceous species are propagated by division, 

 and all may be grown from seeds sown in a frame 

 or in pots in a greenhouse, and pricked out a few 

 inches apart when large enough to handle. 



Soil. Any good loamy soil for the larger species, 

 ami a lighter one of loam, sand, and leaf soil for 

 the Alpines. 



Other Cultural Points. The greater number are 

 hardy, but some of tlie sub-shrubs should occupy a 

 shrltiTcd position, where they are not exposed to 



Ilii/irnutt-liera (see Miirinrifi). 

 Jlyijcricopsis (see f'ranf.enia). 



cold winds. Several grow well under the shade of 

 trees, and calycinurn is occasionally used as a 

 cover plant for game, or for covering bare spots 

 in parks.
