order (Crucifer*). Sow seeds outdoors in April or May where 
required to grow, and thin out the seedlings to 6in. apart. 
A warm border or bed and a well-drained rich soil is necessary 
to grow this plant well. 
Scutellaria (Skull-cap; Helmet Flower). — Hardy peren- 
nials, belonging to the Lavender order (Labiatas). They are 
rather weedy-growing plants, and few are to be recommended 
for culture except in very large gardens. The only ones 
worthy of a place are : S. alpina, a trailing, European species, 
with purple and yellow flowers borne in August ; S. japonica, 
a trailing Japanese species, with blue flowers borne in summer ; 
S. macrantha, a native of Siberia, bearing blue flowers in 
August, and growing ift. high ; and S. orientalis, a creeping 
species from Asia, bearing yellow and purple flowers in 
August. The foregoing species are suitable for growing on 
partially shady rockeries, in deep, sandy, well-drained loam. 
Plant in spring. Increased by division in spring. 
Sedum (Stonecrop). — Hardy perennials, belonging to 
the Houseleek order (Crassulaceae). Some of the species 
thrive on old walls, others as edgings to beds or borders, and 
others again in the mixed border. All are easily grown, 
interesting in the diversity of form of their foliage, and not 
at all wanting in the beauty of their flowers. The following 
are the dwarf species suitable for wall culture or growing 
as edgings to borders, and for carpet bedding : S. acre, 3m. ; 
flowers yellow, June; Britain. S. acre aureum, leaves golden-
