while small and again as they need. The 

 soil used should be light and fibrous and 

 fairly rich. If properlj' managed they should 

 begin to blossom in early autumn and con- 

 tinue for several weeks. The dying of the 

 leaves indicates the approach of' the resting 

 period. Water should then be withheld, the 

 plants being allowed to become dry without 

 shrivelling. At this time the temperature 

 should be kept below fifty degrees. About 

 midwinter the bulbs will cominence to grow 

 and the most active may be planted; others 

 later for succession. The old soil and dead 

 roots should be removed before repotting. 



GoDETiA. Sow in early spring under glass, 

 and when the seedlings are about three 

 inches tall transplant about fifteen inches 

 apart in rather poor soil. In rich soil the 

 plants become rank and produce fewer and 

 poorer flowers. They inay also be started 

 in a coldframe or in the open ground, but 

 are later than if transplanted from the green- 

 hotise. 



GoLDENROD (Solidago). Transplant choice 

 specimens from the fields and fence rows. 

 They respond well to good treatment. 



GoMPHRENA. See Globeflower. 



Grape Hyacinth. See Hyacinth, Grape. 



Grevillea. See Silk Oak. 



Groundnut, Hog (A pios tuberosa). Plant 

 tubers three inches deep in light soil well 

 exposed to the sun. Three or four should be 

 planted together. Provide trelhs upon which 

 the vines may twine for eight feet. Dig and 

 divide annually to prevent undue spreading. 



Gypsophila. See Baby's Breath. 



Helianthemum. See Sun-rose. 



Heliaxthus. See Sunflower. 



Helichrysum. Sow in any garden soil 

 when the soil becomes warm. Allow from 

 one to two feet between plants If desired, 

 seeds may be started in a mild hotbed or green- 

 house and the seedlings transplanted when 

 about two inches tall, and later to the garden. 



Heliotrope. Propagate by means of 

 cuttings of terminal shoots in moist sand. 

 Pot the rooted cuttings in light, rich pottmg 

 soil; provide good drainage, but never let 

 the plants suffer for want of water. Since 

 the plants make rapid root growth, they need 

 frequent changes of pots. For use in the 

 garden, set the plants out after danger of frost 

 has passed, choosing a sunny place and light, 

 rich soil. They should be about thirty 

 inches apart. 



Helipterum. Sow seeds in a mild green- 

 house or hotbed m early spring; transplant 

 to small pots or flats when about two inches 

 tall and set in ordinary garden soil when the 

 weather becomes settled. Allow about a foot 

 between plants. Seeds may also be sown 

 in the garden when spring has opened. 



Hellebore. All cultivated like H . Niger. 

 See Rose, Christmas. 



Hemp. Sow seeds in good soil where the 

 plants are to remain and thin out the seedlings 

 to stand about eighteen inches apart. Use 

 only for backgrounds, since the plants are 

 tall growing. 



Hesperis. See Rocket, Sweet. 



Heuchera. See Coral Bells. 



Hollyhock (Althcea). Plant the seed in 

 January in a cool greenhouse, using ordinary 

 potting soil. When the seedlings are large 

 enough, pot them singly in small pots and as 

 occasion may demand shift them to larger 

 pots until the weather becomes settled in 

 spring, when they may be planted where they 

 are to remain in the garden. A light, deep, 

 rich soil suits them best, but they will grow 

 in poor soil. Allow three feet between 

 plants. If started thus, flowers may be 

 expected the first season, but if started in the 

 garden they will not flower until the following 

 season. Since they frequently fail to produce 

 well the third year, successional anntial 

 sowings should be made. 



Hop {Humulus). Sow seeds of Japanese 

 annual as soon as the ground becomes warm, 

 choosing deep rich soil. Provide a trellis 

 or strings twelve or more feet high. The 

 perennial hop may be grown similarly from, 

 seed or established clumps may be divided 

 in spring. 



Hose in Hose. See Canterbury Bells. 



Hyacinth. Plant bulbs in autumn, four 

 or five inches deep in ordinary soils, shallower 

 in heavy, deeper in light. Protect in the 

 North with a light mulch of litter or leaves, 

 which must be removed in spring. When 

 leaves have turned yellow, dig up, dry in the 

 shade, clean and store until autumn. 



Hyacinth, Grape {Miiscari). Plant the 

 bulbs in any moderately fertile soil during 

 autumn, sinking them about two inches 

 deep. They may be allowed to remain until 

 they show signs of deterioration, when, after 

 the tops have died down, the}' may be dug, 

 cleaned, dried and replanted at the proper 

 season. The foliage should always be allowed 

 to die naturally, since bloom of the following 

 season depends upon foliage of the present. 

 May be planted in lawns like snowdrops. 



Hyacinth, Star. See Aconite, Winter. 



Hyacinth, Summer {Galtonia) . In spring 

 plant the bulbs four or more inches deep in 

 rich, moist, but well-drained soil. In the 

 North dig the bulbs after the tops have died, 

 or protect with a mulch of leaves or litter 

 over winter. In favoured situations and 

 warmer regions this latter method gives best 

 results, since the plants do best when undis- 

 turbed and allowed to grow in clumps for 

 several years. 



Ice-plant (Mesembryanthemnni) . Sow 

 seeds in a sunny place in sandy soil as soon 

 as the ground becomes warm in spring. 

 Thin to about six inches. For indoor use
