HEL 



low flowers. Cuttings of short shoots m sandy 

 soil, under a hand-light, in May ; sandy loam and 

 a little peat. They require the protection of a 

 cold pit in winter, but would do against a conser- 

 vative wall, where they could be protected from 

 severe frost.

 to Gardenia.) 



Stove evergreen shrub. Cuttings of young 

 shoots in sand, under a bell-glass, and in a brisk 

 bottom-heat ; fibry peat and sandy loam, with a 

 little dried leaf- mould. Summer temp., 60 to 

 80 ; winter, 48 to 53. It would probably suc- 

 ceed grafted on Garde'niaflo'rida.

This is the source of the Partridge-pea of Mar- 

 tinique, but not of the Partridge-wood, as has 

 been erroneously asserted. Stove evergreen tree. 

 Cuttings of firm young shoots in a brisk heat ; 

 sandy loam and a dash of peat. Summer temp., 

 60 to 85 ; winter, 50 to 55.

 collar ; in reference to the curious forma- 

 tion of the flowers. Nat. ord., Orchids 

 [Orchidacese]. Linn., 2Q-Gynandria 1- 

 Monogynia. Allied to Trichopilia.) 



Stove orchid. Division of the plant ; shallow 

 basket, in fibry peat, sphagnum, charcoal, and 

 decayed wood. Summer temp., 60 to 90 ; win-

HELE'NIUM. (Named after the beau- 

 tiful Helena, cause of the Trojan war. 

 Nat. ord., Composites [Asteracese], Linn., 

 IQ-Syngenesia 2-Superflua.) 



Hardy herbaceous perennials, with yellow 

 flowers. By division of the plant in spring; 

 common garden-soil. There are some annuals 

 and biennials, but not deserving cultivation.

HELIA'NTHEMUM. Sun Eose. (From 

 helios, the sun, and anthemon, a flower. 

 Nat. ord., Hock-roses [Cistacese]. Linn., 



If gardeners would turn their attention to 

 these Rock-roses, and cross them judiciously, 

 they might expect in time to produce a race 

 \ ; ich would rival the Verbenas. Annuals, by 

 seeds in the open border, in April. A few of 

 the best shrubby ones are rather tender, and 

 young plants might be saved in a cold pit. 

 Shrubby evergreens, by inserting little pieces of 

 ripened and half-ripened shoots with the leaves 

 attached, in June, in sandy soil, in a shady place, 

 under a hand-light. Few things can surpass the 

 beauty of these plants when trailing over stones, 

 and banks, and rock-works, in spring and sum- 

 mer. In such positions, the tenderest merely re- 

 quire, at times, an evergreen branch placed over 

 them in winter; sandy loam, with a little peat, 

 suits them well.
