174 PLANT PROPAGATION 
(from three to four years), offsets from old bulbs are 
the usual means of propagation. 
ScORZONERA.—See Salsafy. 
SCUTELLARIA (SKULLCAP).-—S. mociniana is a very 
pretty bright scarlet-flowering stove plant. Cuttings of 
rather firm shoots strike readily in spring. The hardy 
species aré-increased by seed and division. 
SEAKALE.—-A very general method of propagating this 
is by root-cuttings. When lifting large roots for forcing, 
cut off the side-roots, or thongs, from 4 inches to 6 inches 
long, cut the top straight across and the lower end 
slanting, tie in bundles, and bury in sand until April; 
then plant with the tops just below the surface in rows 
2 feet asunder and 18 inches from each other in the row. 
Seed is also used, and sown at the end of March or early 
in April in drills 1 foot apart, the seedlings being thinned 
to 6 inches apart. Lift the roots in the following 
February, cut off crowns and buds to check them from 
running to flower, and replant 18 inches apart in rows 
2 feet asunder. But if for forcing under pots where 
growing, the plants should be 2 feet apart and the rows 
24 feet asunder. | 
Sepum.—Most of the Sedums can be easily increased 
by seed, cuttings, or division in spring. S. spectabile 
and its handsome varieties are worth growing not only 
for their abundant heads of blossoms, but also for their 
attraction for the beautiful Peacock Butterfly, which is 
an added beauty when hovering with expanded wing's in 
the sunlight. 
SELAGINELLA.—The propagation of these is generally 
very easily accomplished by division, and especially by 
cuttings or small pieces of non-fruiting growth detached 
and planted in light sandy compost and kept moist and
