ALPINE FLOWERS FOR GARDENS 



[PART II. 



and it therefore requires a dry well- 

 drained part of the rock-garden, and 

 should have a little protection in 

 winter during severe cold and wet. 

 J. perennis is taller, often above 

 1 foot high, with dense heads of bright 

 blue flowers, from June to August ; 

 it is a rock-garden plant, stronger 

 than the preceding, thriving in good 

 light loam, and a native of the 

 mountains of Central and South 

 Europe. These perennial kinds may 

 be propagated best from seed, as they 

 do not divide well. /. montana is a 

 neat, hardy annual, with small, pretty 

 bright blue flower-heads in summer. 

 Seed in autumn or spring. A native 

 plant. 



JASMINUM (Jasmine). Beautiful 

 shrubs, the hardy ones among the 

 best introduced to our country, and 

 of very wide and precious use. Where 

 any bold rock-gardening is carried out, 

 these should be used, and may be 

 very gracefully used. They are so 

 often the victims of crucifixion against 

 walls, that it will be pleasant to see 

 them showing their native grace of 

 habit. 



Jasminum humile (Mian Yellow 

 Jasmine). A handsome kind, hardy, with 

 evergreen foliage, which adds to its value. 

 It flowers freely, and its yellow bloom 

 amidst the deep green foliage is welcome 

 in summer and autumn. Being an Indian 

 plant, it should have a warm aspect and 

 good warm soil. (Syns., J. revolutum and 

 J. wallichianum.) 



J. nudiflorum (Winter Jasmine). A 

 lovely Chinese bush, which is happy 

 enough in our northern climate to flower 

 very often in the depth of winter, cluster- 

 ing round cottage walls and shelters, and 

 often more lovely when not too tightly 

 trained. In wet years it will be noticed 

 increasing as freely as twitch at the points 

 of the shoots. It should be planted in 

 different aspects, so as to prolong the 

 bloom. 



Jasminum officinale (White Jasmine). 

 The old white Jasmine of our gardens, one 

 of the most charming shrubs ever intro- 

 duced for warm banks ; it is best on rocky 

 or sandy soils. There are several varieties 

 of it, the best being J. affine, with flowers 

 larger than those of the ordinary kind. It 

 is almost evergreen, except in exposed 

 places. 



It is a native of Persia and the north- 

 western mountains of India, naturalised 

 here and there in Southern Europe. ^ 



JEFFERSONIA DIPHYLLA (Twin- 

 leaf]. A plant very little grown, and 

 usually regarded as a botanical 

 curiosity ; but when planted in sandy 

 peat associated with plants like the 

 Epimedium, Rhexia, and Spigelia mari- 

 landica, it becomes a pretty spring 

 flower, as well as interesting from its 

 curiously paired leaves. The flowers 

 are white, with yellow stamens, about 

 an inch across, and freely borne when 

 the plant is in vigorous health. 

 A good plant for peaty and somewhat 

 shady spots on the rock-garden, 

 planted in sandy peat. A native of 

 rich woods in North America. -Care- 

 ful division in winter. 



JUNIPERUS (Savin). Often grace- 

 ful bushes of the great Pine family, 

 clothing the alpine rocks where the tree 

 has no chance from poverty of the rocky 

 soil and exposure. Few evergreen rock 

 shrubs are more useful for a quiet 

 and graceful effect than the common 

 Savin and its forms, and ^ particularly 

 that known in Nurseries as the 

 Tamarix-leaved Savin (J. tamarisci- 

 folia), for carpeting stony ground, 

 planting on dry banks where little 

 else could grow. Some of the northern 

 dwarf forms of Juniper are grown 

 on rock-gardens under the name of 

 J. nana.
