HEDERA 



HEDGES 



gated middle lobe and 1 or 2 short spreading lobes on 

 each side at the base: rather more pubescent, stellate 

 hairs with about 8 rays. Crimea. Possibly hybrid of 

 H. helix and H. colchica. The following are some of 

 the most remarkable of the horticultural forms: Var. 

 arborescens, Loud. (H. arborea, Hort.). Not climbing, 

 forming an erect, low shrub: Ivs. ovate to elliptic, 

 entire. This variety is gained by using flowering 

 branches for prop. There are also some variegated 

 forms, as Silver Queen, with silvery variegated Ivs. 

 Var. baltica, Hort. A small-leaved form hardly differ- 

 ing from the type; the hardiest or one of the hardiest 

 of the forms in cult. Var. Cavendishii, Koch (var. 

 marginata minor, Hort.). Slow-growing, with rather 

 small dull green Ivs., edged creamy white, striped red 

 or pink in fall. Var. conglomerata, Nichols. Slow- 

 growing: Ivs. crowded, small, entire or 3-lobed, undulate. 

 R.H. 1890, p. 163. Var. crenata, Hibberd (H. 

 vitifdlia and H. digitdta nova, Hort.). Similar to var. 

 digitata, but lobes shorter and broader, crenate at the 



1789. Hedera helix. Form with white-ribbed leaves. 



margin, light green. Var. deltoidea, Hibberd (var. 

 hastata, Hort.). Lys. rather small, bluntly deltoid, 

 almost entire, blackish green, changing to dull purplish 

 bronze in fall. Gn. 25, p. 141; 34, p. 493 (as A. hastata). 

 Var. digitata, Loud. Lvs. rather large and broad, 

 digitately lobed with 5 triangular-oblong lobes, some- 

 times with 2 small additional basal lobes, truncate at 

 the base, dark green. Gn. 25, p. 141; 34, p. 493. Var. 

 gracilis, Hibberd. Lvs. rather small, with broad, 

 short lobes, dull green, bronzy in fall. Gn. 59, p. 154. 

 Var. lobata major, Hibberd. Similar to var. hibernica, 

 but Ivs. somewhat smaller, more deeply lobed and 

 lobes narrower. Var. lucida, Hibberd. A form of var. 

 chrysocarpa, with large deltoid Ivs. not lobed or partly 

 or slightly 3-5-lobed, glossy above: a vigorous grower. 

 Gn. 25, p. 141; 34, p. 492. Var. lusitanica, Hesse. 

 Similar to var. palmata. Lvs. large, to 5 in. across, light 

 green, palmately 5-lobed with triangular lobes. Var. 

 maculata, Hort. (H. latifblia maculata, Hort.). Similar 

 to var. hibernica: Ivs. spotted and striped yellowish 

 white. Var. marginata, Hort. Lvs. broadly triangular- 

 ovate, irregularly bordered yellowish white, striped 

 red or pink in fall: of somewhat slow growth. F.E. 

 31:318. Var. marmorata, Hort. Similar to var. 

 hibernica, but Ivs. irregularly blotched yellowish white. 

 Var. minima, Hibberd (var. donerailensis, Hort.). Lvs. 

 small, 3-lobed or pedately 5-lobed, with short and 

 spreading basal lobes, dull purplish brown in winter. 

 Gn. 59, p. 154. M.D.G. 1897:229 and S.H. 2:237 (as 

 var. digitata). Var. palmata, Hort. Similar to var. 

 digitata, but Ivs. 3-5-lobed with broader distinctly 



triangular lobes, the lateral ones more spreading, dull 

 green. Var. pedata, Hibberd. Lvs. pedately 5-lobed, 

 the middle lobe long and narrow, the lateral lobes 

 much shorter, dark green with whitish veins. Gn. 25, 

 p. 141; 34, p. 493; 59, p. 154. Var. sagittifSlia, Koch. 

 Lvs. rather small, with triangular middle lobe and short, 

 broad and obtusish lateral lobes, deeply cordate at the 

 base, dull dark green. Var. tesselata, Nichols. Lvs. 

 3-lobed with short and broad lobes, with a distinct 

 reticulate variegation. J.H. III. 28:209; 45:99. Var. 

 tortuSsa, Hibberd. Lvs. ovate or rhombic, entire or 

 obscurely 3-lobed, more or less curled and twisted, the 

 curling increasing during cold weather. Gn. 55, p. 336. 

 Var. tricolor, Hibberd (var. marginata rubra, Hort., 

 var. elegantissima, Hort., var. Cullisii, Hort.). Like 

 var. marginata, but edges of Ivs. becoming red in fall.

HEDGES. Living green fences are used for two dis- 

 tinct purposes defense and ornament. Ornamental 

 hedges may be rendered defensive by stretching tightly 

 two or three strands of barbed wire through the center 

 of the hedge. So far, no plant has yet been tested that 

 meets all the requirements of the farmer for a truly 

 impassable barrier, although the Osage orange (Madura 

 pomifera) possesses more recommendable features 

 than any other hardy tree. This tree, however, is not 

 hardy in the northernmost states. For regions south 

 of Washington, D. C., Kentucky, and Missouri, 

 Poncirus (or Citrus) trifoliata is of equal value. Both 

 have the serious drawback of being subject to the 

 attacks of the San Jose" scale, but no satisfactory sub- 

 stitute has yet been found. 



Next to these, perhaps, ranks the honey locust
