REHMANNIA. 



Rehmannia. -The Rehmannias suggest in their flowers that a 

 baa married a Salpiglossis. Of this last they have the floppy, 

 limp texture, the veinings and suffusions of colour; and their shape is 

 intermediate between the long bell of the Foxglove, whose spire they 

 flaccidly emulate, and the wide bell of the^ Salpiglossis. They are a 

 lush, soft looking race, but may be grown as hardy plants in well- 

 sheltered, warm comers of loose, rich soil, well-drained , where they have 

 their value hi summer, when they help to fill the interval with their 

 loose and leafy spires of hanging, wide-mouthed Foxgloves. It may 

 be well to grow 18-inch R. elata (wrongly called R. angulata) and 

 R. sinensis (glutinosa), and the dwarfer hybrid, R. kewensis, of the 

 yet dwarfer Chinese novelty, R. llenryi. 



Reineckia carnea is a little Japanese Liliaceous plant, freely 

 stoloniferous and spreading and easy, with tufts of narrow grassy foliage 

 like that of Ophiopogon, with small violet flowers coming up at the 

 sides, on Btemless spikes, close to the ground, all the summer through. 



Reseda. — The wild Mignonettes have no real value. R. complicate, 

 is a 2-foot semi-shrub from Spain, for rather shady slopes, whilo 

 much dwarfer, and for warmer, sunnier slopes may be chosen 10-inch 

 7?. glauca, with bluish foliage and the usual little insignificant spikes 

 of flower, all through the summer ; whilo R. sesamoeides (like both 

 the others, a Spaniard), is quite dwarf, creeping and ramping. Seed 

 and division. 



Rhabdothamnus Solandri is a fine, greyish-leaved, straggling 

 shrublet from New Zealand, with little orange-red foxgloves striped 

 inside with scarlet. Its hardiness is rather more than doubtful, and it 

 seems often a sullen and reluctant grower even in good soil. 



Rhamnus alpinus is the rock-sheeting shrub, tight-pressed, 



with bright green foliage and subsequent black berrics ; that often 



; pleasure on the alpine cliffs, and can easily be made to do as 



much at home. R. pumilus is no longer so adherent to the pavement, 



and there are many other species, not germane to this garden. 



Rhaponticum must all be looked for, either as SerratuJa or as 

 Gentaurea. Rh. cynaroeides is a large Artichoke, and Rh. scariosum a 

 large Centaurea. 



Rhazya orientalis and Rh. stricta both want the sunniest of 

 places (mi the warmest of well-drained slopes. They are Dogbanes. 

 The latter is pretty hopeless — a yard -high bush like Daphne Laureola 

 with heads of whitish stars ; the former is more practicable — a 10-inch 

 plant of unbranched leafy shoots, enveloping a head of little blue 

 stars among the uppermost leaves in late summer. The first is 

 tropical, the second only Ln vantiri >.
