Sedum spectabile Sedum Sieboldi 
SEDUM. Stonecrop. A genus of plants which vary in habit 
from dwarf, creeping plants to those of larger growth. Some 
are evergreen, and others deciduous. The dwarf kinds do 
well as edgings to borders or in rock-gardens; others are 
suitable for grouping in the border. They are the easiest 
of all plants to grow. Ordinary soil and dry, sunny borders, 
or rock-garden, will suit all.

fully exposed positions and in stony and poor soils, turns to 
a lovely rich deep red. Flowers are pure white, tinged pink. 
*Lydium glaucum. (SL) A blue-leaved form of the preceding. 
*Middendorffianum. (SL) Low tufts of erect stems clothed 
with narrow, serrated, reddish brown leaves which form a 
pretty contrast to the rich yellow flowers. 3 to 4 in. 
*Pruinatum. (L) Pretty glaucous blue-green leaves. Yellow

*STATICE latifolia. Sea-Lavender. (L) Immense heads of 
purplish blue, minute flowers during July and August. 
These, if cut and dried before fully expanded, last in perfect 
condition for months. A sandy loam is essential to grow 
these plants well; they will not thrive on heavy soils. A 
sunny position is indispensable. A valuable plant for the 
border or rockery. 
STOKESIA cyanea. Stokes’ Aster. (L) A handsome perennial 
that resembles both a China aster and a cornflower. Beauti¬ 
ful light blue flowers, produced from July until frost, on 
1 D-foot stems. One of our best late summer-flowering 
perennials. Especially recommended for the front of a 
border, and may be used for cut-flowers. Grows well in a 
sunny, well-drained border, in sandy loam. 
SWEET WILLIAM. See Dianthus barbatus. 
THALICTRUM adiantifolium. Meadow-Rue. (L) A hardy 
perennial with elegant, finely divided foliage, which is most 
useful for cutting and mixing with cut-flowers. Many yellow 
flowers in June. The plants are of easy cultivation, thriving 
in any good, common, ordinary well-drained soil. May be 
grown in a sunny or partially shaded border. Effective as 
single specimens in shrubbery borders or wild gardens. 
THYMUS. Thyme. Covered completely during June and July 
with brilliant flowers, the Thymes make a beautiful display 
in the rockery, along sunny banks or dry rocky slopes, in the 
wall-garden, and between stepping-stones. The fragrant 
foliage makes an excellent carpet for the spring bulb beds. 
Plants will thrive in ordinary soil, in well-drained situations, 
in full sunlight. They soon spread and form neat patches of 
foliage covered with blooms. 
*Citriodorus. Lemon Thyme. (SL) Foliage has a strong lemon 
fragrance. Flowers rosy pink. 4 in.

wealth of blue flowers all summer, on blue-green stems about

nothing else will thrive. Suitable for naturalizing in the wild 
garden, woodland, or shrubbery borders.
