SHRUBBY A^D SUB-SHRUBBY FLOWERS. 137 



The Double Yellow Callage Rose, or Yellow Provence 

 — R. sulpliurea — approaches the Provence in name only, 

 and in similarity of form of the expanded blossom, being 

 essentially alien in descent to that and most other roses. 

 When well bloomed it is a horticultural gem, but is so 

 difficult to manage as to make it, in that case, a horti- 

 cultural triumph. As to situation, I have never seen it 

 blossom well, either in Britain or on the Continent^ 

 except when growing at the foot of a low wall, over the 

 top of which it could straggle as it pleased ; for it will 

 not submit to pruning. It is' one of the roses (among 

 which are included the pretty little climbing JBanJcsias, 

 with their white or nankin-coloured tufts of tiny violet- 

 scented flowers) which cannot bear even the smell of cold 

 steel. Tou might not unreasonably expect them to 

 refuse to flower if you come near them with a knife in 

 your pocket, even if you do not take it out and open it. 

 Tou may get rid of their dead and used-up wood as well 

 as you can, by breaking it off ; but the effluvium of iron 

 agrees not with their constitution. A south aspect does 

 not suit the Cabbage Yellow, while plenty of evidence 

 exists to prove that the best chances are had in the 

 above-stated position, or some near approach to it. Mr. 

 Paul tells us : — " At East Lodge, on Enfield Chase, there 

 was a plant on its own roots, growing at a distance of 

 about ten yards from a wall with a north-eastern aspect. 

 It here produced its beautiful yellow blossoms abundantly ? 

 covering the bush on all sides, during the flowering season, 

 for several successive years. This situation is high and 

 exposed : the soil is naturally a heavy loam, but was some- 

 what lightened and enriched by the frequent addition of 

 stable manure. At Ballater, in Scotland, both this and the 

 Austrian Rose flower beautifully. They grow there most 

 luxuriantly, in a very exposed situation, covering a wall of 

 great height and extent, laden with perfect flowers." Mr. 

 Rivers tells us : — " At Burleigh, the seat of the Marquis 

 of Exeter, the effect of situation on this rose is forcibly 

 shown. A very old plant is growing against the southern 

 wall of the mansion,in a confined situation, its root cramped 

 by a stone pavement : it is weakly, and never shows a
