slightly interspersed at the margin 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 he is placing 

 them irregularly, the result often being almost the 

 same as that of two rows. If the group is being planted 

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

 tances of the successive plants from this line might be 

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

 three feet, one foot, and the distances apart, measured 

 parallel with a fixed line, should vary also. 



The ideal condition of a group of shrubbery is to have 

 all the individual plants healthy, so that the foliage will 

 appear fresh and of good color. This foliage should 

 extend down to the surface of the adjacent lawn or walk, 

 and shade the ground underneath so completely that 

 nothing will grow there. The leaves which fall with 

 the approach of winter should be allowed to remain as 

 a perpetual mulch. The desired result cannot be 

 secured the first year the shrubs are planted unless 

 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 be well to cut it off next to the 

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

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

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

 graceful way. If it encroaches upon the walk, cut 

 away the encroaching branch near the root so that the 

 mark of the knife will not be noticed. Such treatment 

 will help to retain the winter beauty of the branches. 



The value of shrubbery is not appreciated as it should 

 be. Those who are interested in the subject will do 

 well to read what is found in the various books on 

 landscape gardening. Bulletin 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. O. C. Simonds. 



SIBBALDIA (Robert Sibbald, Scotch naturalist). 

 'Bos&cea. About 5 species of alpine plants, one of which 

 has been suggested as suitable for rock gardens. The 



SICANA 



genus IS reduced bj Bentham and Hooker to a section 

 of Potentilla but Bntton and Brown keep it separate 

 chiefl-v on the giound that the pistils are only 4=-12 in 

 number insteid of veiv numerous as in Potentilla. Sib- 

 baldias are dcnseh tufted hardy perennial herbs with 

 woody stems The hs hive prominent stipules and 3 

 leaflets each of which is chaiaoteristically 3-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 cahx which has 5 broad 

 lobes alternating with 5 smaller and 

 nariower lobes or bracts.

SIBTHCEPIA (John Sibthorp, pro- 

 fessor of botany at Oxford, author 

 of Flora Grseca, published 1806-15). 

 Sci ophulai lAcew . A genus of about 

 6 species of hardy or tender peren- 

 nial creeping herbs mostly from the 

 tropical rCi^ions, 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 subrotate, with a very 

 short tube 5-b cleft; stamens usually 

 equal to the number of corolla-lobes; 

 anthers sagittate: capsule membran- 

 ous, compressed, loculicidally dehis- 

 splitting to the middle. 

 Europiea, 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. 

 Deep woods, Europe. -Offered in 1893 by John Saul, 

 Washington, D.C. Var. varieg4ta is cult, abroad.

 wide-spreading or reflexed calyx-lobes and the aiitliers
