HELIPTEBUM 



kinds are annual herbs for grown as such), of easiest 

 cultivation in any garden soil. Fls. mostly perfect, with 

 5-toothed open corollas: akenes woolly, bearing a pap- 

 pus of many plumose bristles: involucre glabrous, obo- 

 vate or top-shaped, silvery or rose-colored: plants 

 mostly glabrous. This and Helichrysum are amongst 

 the most important of everlasting flowers. 

 A. Heads large, many-flowered. 

 B. Lvs. broad. 

 MAnglesii, Muell. {Rhoddnthe Mdnglesii, Lindl. Boc- 

 cdrdia Mdnglciii, Voss). Fig. 1033. Neat glaucous an- 

 nual, 12-18 in. tall, with very slender, long pedicels, 

 bearing pretty nodding heads : lvs. thin, oval or elliptic, 

 clasping: involucre silvery-chaffy, the ray florets origi- 

 nally clear, handsome pink, but now varying to white 

 {B. dlba, Hort.), and to dark red (R. atrosanguinea, 

 Drumm.). Var.maculAtum (7?. macwidta, Drumm. Roc- 

 cdrdia Mdnglesii, var. maculAta, Voss), is usually 

 larger,with shorter lvs. and involucre flecked with red: 

 rays pink or white. Austral. B.R. 20:1703.— A charm- 

 ing plant, and one of the few everlastings which retains 

 much of its grace and beauty after being dried. There 

 are double-fld. forms, i.e., those with all or nearly all 

 the florets ligulate. Excellent also for pot culture. 

 Seeds of the mixed vars. are sometimes sold under the 

 name Rhodanthe I'aritis.

HELLfiBORDS (ancient name of B'.orienin^is, mean- 

 ingunknown). RanunculiiLcew. Hardy herbaceous per- 

 ennials, about 8 species, natives of Europe and western 

 Asia. Erect, with large palmately divided lvs., the ba- 

 sal long-petioled, the upper sessile and sometimes re- 

 duced to bracts: fls. large, white, greenish, red, purple, 

 or yellowish; sepals 5, broad, petal-like, mainly persis- 

 tent; petals small, tubular, furnished with claws; sta- 

 mens many ; carpels 3-10, sessile, forming leathery, 

 many-seeded capsules, dehiscent at the apex. 



All the kinds will thrive in ordinary garden soil, but 

 for the best results use a soil of rich loam and coarse 

 sand, with a top-dressing of rotten manure. A moist, 

 well-drained, partially shaded situation is preferable. 

 The species may be planted in shrubbery holders, and 

 in rockeries, or if wanted for cut-flowers they should be 

 planted in beds. An important point is not to disturb 

 the plants when once established, as they are very sen- 

 sitive to frequent changes of location. All the species 

 bloom before spring arrives; a few mild daysin Decem- 

 ber or January will bring out the buds of H. niger va- 

 rieties, and the others are not far behind. They are 

 easily forced under glass. Strong plants should betaken 

 u]> iTito large pots and gradually inured to a warm tem- 

 ]■' !-..'!.,.■. Blossoms may thus be brought forth at any 

 1. a in winter. Prop, best by division in fall or 

 lilt if seeds mature they will germinate well
