SHRUBBERY 



SICANA 



in a continuous border there should be places where 

 shrubs of larger size occupy the full width so as to 

 bring growth of considerable height into the lawn. The 

 arrangement should be varied so as to avoid all 

 monotony, but in securing this variation a mixture of 



miscellaneous shrulis of all

slightly interspersed at the nmrgin with shrubs of 

 another kind. Straight rows should be avoided. A 

 laborer or a novice when told this will arrange the 

 plants in a zigzag manner, thinking that be is placing 

 them irregularly, the result often being almost the 

 same as that of two rows. If the group is l^eii^g planted 

 along a straight line, as the boundary ot a lot, the dis- 

 tances of the successive plants from this line might be 

 somewhat as follows : two feet, four fret, five feet, 

 three feet, one foot, and the dist;nices apart, measured 

 parallel with a fixrd line, should vary also. 



The ideal condition of a grnup of shrubl)ery is to have 

 all the indi\''idual plants healthy, so that the foliage will 

 appear fresh and of good color. This foliage should 

 exten<l down to the surface of the adjacent lawn or walk , 

 and shade the ground umh'rnuLtth so completely that 

 nothing will grow there. Tlie leaves which fall with 

 the approach of wiidi-r should lie ;il]owed to remain ;is 

 a perpetual mulch. Tin- desired res\dt cannot 1 e 

 secured the first year the shrubs are jilanted urdess 

 they are of large size and moved but a short distance. 

 The aim in caring for a new plantation should be to 

 secure thrifty plants, and this care, like the preparation 

 of the soil, should be such as is given to a field of corn. 



Very little trimming should be done. If a bush is tall 

 and spindling it may Ue well to cut it off' next to the 

 ground and allow it to sprout again. If there is any 

 dead wood it should, ot course, be cut off. But when a 

 shrub is healthy and vigorous, let it grow in its own 

 graceful way. If it encroLiches upon the walk, cut 

 away the encroaching brjuudi nejir the root so that the 

 mark of the knife will not In- notirrd. Such trciitraent 

 will help to retain the winter beauty of the branches. 



The value of shrubbery is not appreciati-d as it sliould 

 be. Those who are interested in the subject will do 

 well to read what is found in the various books on 

 landscape gardening, Bulirtin No. 121 of Cornell Uni- 

 versity Agricultural Experiment Station, the various 

 articles on shrubs and shrubbery to be found in the ten 

 volumes of "Garden and Forest "and in other horticultu- 

 ral journals. ^_ (,_ gj,,^^.^,^^ 



SIBBALDIA {Robert Sil)bald, Scotch naturalist). 

 BosarefF. About 5 species of alpine plants, one id' which 

 has been snggested as suitable for rock gardens. The 



genus is reduced by Bentham and Hooker to a section 

 of Potentilla, but Britton and Brown keep it separate 

 chiefiy on the ground that the pistils are only 4-12 in 

 number instead of very numerous as in Potentilla. Sib- 

 baldias are densely tufted, hardy perennial herbs with 

 woody stems. The Ivs. have prominent stipules and 3 

 leaflets, each of which is characteristically ii-toothed at 

 the apex. The fls. are about ^ in. 

 across or less, and have 5 minute yel- 

 low petals much smaller than the re- 

 markable calyx, which has 5 broad 

 ^ lobes, alternating with 5 smaller and 



narrower lobes or bracts. 



procumbens, Linn., ranges from the 

 arctic regions to the summits of the 

 White Mts. and in the Rockies comes 

 as far south as Utah. It is also found 

 in arctic and aljiine Europe and Asia.

SIBTH6RPIA (John Sibthorp, pro- 

 fessor of botany at Oxford, author 

 of Flora GrEeca, published 1806-15). 

 ."ScrophulaHdceiP . A genus of about 

 (> species of hardy or tender peren- 

 nial, creeping herbs mostly from the 

 tropical regions, with alternate or 

 tufted roundish, long-petioled Ivs. and 

 yellow, orange, or red fls. solitary on 

 axillary or fascicled pedicels: calyx 4- 

 5-cleft; corolla snbrotate, with a very 

 ■^ ' short tube, 5-8-cleft; stamens usually 



-A billow of equal to the number of corolladobes; 



anthers sagittate: capsule membran- 

 ous, compressed, locxilicidally dehis- 

 cent, the valves splitting to the middle. 



Europaea, Linn. A hardy trailing perennial with very 

 slender stems : Ivs. orbicular, less than K in. across, 

 7-9-lobed: fls. small, on rather short pedicels, the 2 

 upper lobes of the corolla yellowish, the 3 lower pink.
