Sedum—continued. 
rarely pink or blue, cymose (see Fig. 463), in a few cases 
axillary and solitary; calyx four or five-lobed; petals 
four or five (rarely six or seven), free; stamens eight 
to ten (rarely twelve to fourteen); filaments filiform or 
subulate. Leaves very variable, opposite, alternate, and 
whorled, entire or serrate, rarely laciniate. Sedums are 
amongst the easiest of plants to grow; like Saxifrages 
and Sempervivums, they succeed in almost any position, 
on rockwork, old walls, or ruins, or in the mixed 
border. Some are specially adapted for use in carpet 
bedding, S. lydiwm being an example. S. acre, and 
its variety aureum, though common, are plants much 
favoured by almost everybody, and allowed to spread 
extensively. 5S. spectabile is a fine, herbaceous border 
plant, also equally well adapted for pot culture. All 
Sedums are readily propagated by seeds, by cuttings, 
or by division of the tufts in spring. They prefer an 
open, loamy soil, and to grow amongst stones, but, as 
before noted, they thrive in almost any position. 
By the assistance of the following key, adapted from 
Dr. Masters’ admirable monograph on the “ Hardy Stone- 
crops” (published in the - “ Gardeners’ Chronicle ” for 
1878), any of the hardy species may be readily identified.

; ~ IIL Annuals or Biennials. 
Stamens ten to twelve. 
Leaver ‘fat, tufted on the barren shoots: S. semper vivoides. 
more or less cylindrical : S. cerulewin, S. glandulosum. 
A selection of the best-known species is given below ; 
they are hardy, herba perennials, except where 
otherwise indicated. For most of the descriptions we 
are indebted to the monograph above quoted.
