SEDUM. Crassulaceae. Stonecrop. Sedums are a rich source of rock 
garden material, and some of them endure drought and dry corners 
where little else will thrive. This is not true of all of them, because 
a few are bog plants, several do best with shade, and the majority en¬ 
joy soft luxury, as opposed to sterile conditions. Like other succulents 
they have a general preference for good drainage, with dry surfaces 
to recline upon. 
All Sedums are offered at 30 cents each, a dozen of one variety for 
$2.50.

erect; fls. light yellow.
