A YEAR'S GARDENING 



fresh ground. Seeds should be sown in spring in a sunny situation 

 and the seedlings transplanted in due course. 



HESPEROCHIRON. A pretty little plant well suited for the 

 Rock Garden, thriving in ordinary soil, of dwarf habit and bearing 

 well-formed, violet-tinted white flowers. 



HIBISCUS (Mallow) . For most of this tribe our climate is not 

 warm enough for open-air treatment, though H. coccineus is often 

 cultivated as a flowering shrub for the conservatory, where its 

 brilliant scarlet bloom makes a fine display. H. africanus is, how- 

 ever, fairly hardy when treated as an annual by sowing under glass 

 in early spring and planting out in a warm border. It is a showy 

 plant, growing about i8 inches high and bearing flowers of creamy 

 yellow with purple markings. H. Trionum is also quite hardy as an 

 annual and wiU often renew itself by self-sown seeds if the winter 

 has been mUd, while H. Syriacus, the well-known Rose of Sharon, 

 grows vigorously in moist soils and has now many beautiful varieties, 

 with flowers of every shade of colour, from white to blue, purple and 

 crimson. 



HIERACIUM (Hawkweed). A hardy annual growing some 12 

 to 18 inches, high, with an abundance of pretty star-like flowers of 

 white, yellow or red. One of its recommendations is that it will grow 

 anywhere, but naturally it is rather weedy in character. 



HOLLYHOCK. See Alth^a. 



HONESTY. See Lunaeia. 



HONEYSUCKLE. See Loniceea. 



HOUSELEEK. See Sempervivum. 



HUMEA. A half-hardy biennial with large, graceful leaves pos- 

 sessing an aromatic odour, and bearing a feathery blossom of russet 

 hue. It makes an elegant plant for the conservatory and its sprays 

 are useful for cutting. Seed shoidd be sown in summer (Jvdy or 

 August) and potted oft in due course for flowering the following year. 

 During winter the plants should be watered with liquid manure and 

 in spring transplanted into larger pots of rich soil. 



HUTCHINSIA. A pretty little rock plant well suited for the 

 Alpine or Rock Garden. H. peircea is found wild on limestone rocks 

 in the west of England and in Wales, eind H. alpina is a stUl smaller 

 plant, with shining leaves and clusters of white flowers. It grows 

 freely in sandy soil and is easily raised from seed.
