hand, if there is plenty of room against a wall or pillar it may be 

 planted out under glass and allowed to ramble, when it will soon 

 cover a considerable area and bloom profusely. Standard Helio- 

 tropes can be formed by pinching out the side shoots to a height of 

 a foot, and then letting a few shoots start. These can be stopped at 

 about 4 ins. long to induce laterals, and so a head is formed. Loam, 

 with a fourth of decayed manure, and some sand, is suitable. 

 Propagation is by seeds sown under glass in spring or by cuttings 

 in late summer in a warm house. Heliotropes are tender plants, 

 but they may be planted out of doors in June. The following are 

 good: Adele, Miss Nightingale, Rose Clair, and White Lady. But 

 the old lilac species, peruvianum, should not be overlooked, as it is 

 very floriferous and sweet. 



Helleborus, Christmas and Lenten Roses (helleb-orus, from helcim, 

 to kill, and bora, food, indicating its poisonous nature. Ord. Ranun- 

 culaceae). : See Bulbs Christmas and Lenten Roses. 



Hemerocallis, Day Lily (hemerocal-lis, from hemero, day, and 

 hallos, beauty, alluding to the brief duration of the flowers. Ord. 

 Liliaceae). See Bulbs. 



Hen-and-chickens. See Bellis (Daisy). The name is sometimes 

 applied to Saxifraga umbrosa. 



Hepatica (hepat-ica, from hepaticos, liver, in allusion to the lobed 

 leaves. Ord. Ranunculaceae) . These charming little plants are 

 now classed with the Anemones by botanists, but they are generally 

 grown separately in gardens. They are beautiful little plants, 

 blooming freely in winter. They are not particular as to soil, but 

 must have shade. Propagation is by seeds. There are several 

 varieties with different colours. 



Herbaceous Borders and Plants. See Flower Garden. 

 Herb Robert, Geranium Robertianum. 

 Herbs. See Kitchen Garden. 



Hermaphrodite. Flowers which contain both male and female 

 organs. 



Herniaria, Rupture Wort (hernia-ria, from hernia, a rupture. 

 Ord. Illecebraceae) . The small species glabra is in demand by carpet 

 bedders, who use it for making lines and cushions of green. It is a 

 hardy plant, not fastidious as to soil, and easily propagated by 

 division in autumn. 



Heron 's-bill. See Erodium. 



Hesperis, Rocket (hes-peris, from hesperos, evening star, alluding 

 to the strong perfume at night. Ord. Cruciferae). Hardy biennials 

 and perennials, thriving in ordinary soil, and easily propagated by 

 seed or division. The Sweet Rocket, H. matronalis, is a perennial 

 with purplish flowers, but the colour is variable. There are several 

 forms of this handsome and fragrant old plant, which will grow 

 almost anywhere, and thrives in chalk. Tristis is a biennial, also 

 variable in colour, and sweetest at night (see the Botanical 

 Magazine, t. 730).
