SEDUM.—Next to the saxifrages the Sedums must surely 
be placed as the most serviceable of plants for the 
amateur’s rockery. So hardy, so accommodating in re- 
gard to situation and soil, some of them capable of growing 
almost without soil, requiring no particular skill in planting, 
and able to withstand scorching drought, and to safely 
come through a prolonged deluge, the Sedums are indeed 
a boon to many rockeries which either from faulty con- 
struction, poor soil, or unfavourable environment would

range of shades. Sedums may have white, golden yellow, 
pink, red, or purple flowers, and some are of prostrate, 
trailing, or pendant growth, some erect, bushy, and of 
almost shrubby appearance, whilst some make neat sym- 
metrical cushions over which short-stalked, flattened 
umbels of bright-hued flowers show to great advantage. 
So many and so beautiful are the species and varieties 
of this easily cultivated genus that it is impossible to 
name and describe them all, and it would be an injustice 
to the rest to single out a few for particular mention. 
The majority are among the cheapest of alpines to buy, 
are easy to increase by division, and as almost every 
plant catalogue contains names and descriptions of a large
