U'2 GLENNYS HANDBOOK 



HESPEIIANTHA. Evening Flower. [Iridiiceae.] Pretty 

 greenhouse or half-hardy bulbs, allied to Ixin, aud requiring 

 the same mode of management. Soil, sandy loam and peat. 

 Increased by offsets. 



HESPEllIS. Rocket. [Cruciferse.] A genus of hardy 

 jdants, annual, biennial, and perennial. Some of the varieties 

 of the common Ptocket {H. matronalis), especially the double 

 white and double purple, are very great favourites in the 

 flower gardens. They are rather difficult to manage, especially 

 in old gardens or in confined situations, for they love fresh 

 soil and an open situation. A light rich loam is the best 

 for them ; but if an artificial compost has to be made up, as 

 it should be if they are required in perfection, a third part 

 of sandy peat mixed with two-thirds of mellow loam will 

 grow them very well. Next to soil, the great secret of success 

 is not to let them stand too long in a place, for under such 

 circumstances they are sure to dwindle. They ought to be 

 taken up and divided every second year, soon after they have 

 done flowering — that is, early in autumn — and replanted in 

 fresh soil. To have a display of healthy plants every year 

 they should he divided into two sets. Those plants respectively 

 which have hloomed in their second year, if taken up in each 

 successive autumn and divided, will furnish a constant supply 

 of young plants, the flowering of which should be prevented 

 in the following summer, and they will then bloom vigorously 

 in the second year from their transplantation. One reason 

 why this constant transplantation is necessary is that the 

 plant, in its original state, is naturally a biennial, perishing 

 after it has produced flowers. The other species, most of 

 which are also biennials, are unimportant compared with the 

 varieties above alluded to. 



HESPEROSCORDUM. [Liliacete.] Half-hardy bulhs. 

 Soil, sandy loam. Increased by offsets or hy seeds. H. 

 hyacinthinum, flowers blue, in July. H. lacteum, flowers 

 white, in July. 



HEUCHERA. [Saxifrat^acese.] Hardy herbaceous per- 

 ennials, with simple-looking flowers. Common soil. Increased 

 by division 



HIBBERTIA. [Dilleniacese.] Ornamental greenhouse 

 evergreen shrubs. They are raised by cuttings planted
