Helmholtzia

Hemerocallis 



Cultivation in Pots and Frames or Pits. With 

 careful attention, the Hellebores may be grown in 

 pots of rich soil, and Mibjected to gentle forcing, 

 if afterwards put outside in a shady position, and 

 well supplied with water during the summer. If 

 grown in frames, the lights should be taken off in 

 all favourable weather. In a few gardens the 

 Christmas Hoses are largely grown in pits where 

 there is a slight heat, and where many blooms are 

 produced by the exercise of care in watering and 

 giving air.

HELMHOLTZIA. 



Two species only of greenhouse perennial herbs 

 (iml. Philydracea;), with sword-shaped leaves, some- 

 thing like those of a Gladiolus. The flowers are 

 borne on tall stems in big, plumy panicles, and 

 are rather pretty. Increase is by "division of the 

 root usually ; occasionally by seeds. Soil, sandy 

 loam and peat in equal parts. They make unsatis- 

 factory pot plants, and are only seen at their best 

 when planted out in a prepared border as in the 

 lemperate House at Kew. 



Principal Species : 



glaberrima, 3' to 4', My., grh., wh. (sun. Phily- 

 dnim glaberrimum of liotanical Magazine <>056). 



HELMINTHOSTACHYS. (INDIAN 

 FLOWERING FERN.) 



A pretty but curious looking stove Fern (prd. 



Helmet Flon-er (see Aconltum, CoryantJtes, and 



Xciitellaria). 

 Jfelmia (ice Dliiscorca). 



Filices), closely related to Botrychium. Propaga- 

 tion is very slow and difficult, as young plants are 

 rarely, if ever, raised from spores, and the only 

 method of increase is by division of the crowns. 

 Soil, loam and leaf mould in equal parts, with sand. 

 Plenty of water is needed during the growing 

 season, but as the plant is deciduous.it needs little 

 during the winter, only enough, in fact, to preveat 

 its succulent rhizome from shrivelling. 



Only Species : 



zeylanica, fronds 1' to 1|' long, barren below, 

 spore-bearing above (syn. dulcis). 



HELONIAS. 



A genus of four species only (<>rd. Liliacese). 

 Bullata, 1' to 1J', summer, hardy, purple rose, 

 small, is a pretty herbaceous perennial from North 

 America. Propagation, by division of the roots, 



HEMEKOCALLIS FIAVA (see p. 411). 



which is, however, a rather slow process, and by 

 seed. The divisions should lie made in spring. 

 Soil, fibrous loam and peat. A moist, shady place 

 is the most suitable. Latifolia is a broad-leaved 

 variety of the species, not a svnonym, as is some- 

 times stated. 



HELWINGIA. 



Curious Asiatic trees (prd. Araliacerc), of little 

 horticultural merit. 



HEMEROCALLIS. (DAT LILY.) 



Bright and effective herbaceous border plants 

 (ord. Liliacere), hardy almost everywhere, and 

 of ranch value, despite the short duration of 

 the individual blooms. Propagation, by seeds 

 sown in spring under glass, but preferably by 

 division just when beginning growth in spring. 

 Any good garden soil will do. The Day Lilies 

 flower best in a sunny situation, and bloom freely
