descriptions. 
Asclepias tuberosa.—Pleurisy-root or butterfly-weed is the 
common name for this plant which is often found growing 
wild in the vicinity of St. Louis. Its adaptability to local 
conditions need hardly therefore be questioned. Blooming 
from August to September and producing flat umbels of 
orange-colored flowers, it is a most satisfactory plant. It is 
best used at the edge of the perennial groups as it flowers 
when about 18 inches high. 
Baptisia—The Baptisia, or false indigo, may be had in 
two colors, blue or yellow. The flowers are shaped like the 
sweet-pea but are borne on erect racemes. They bloom in 
May or June in this locality, and although the flowering 
period is of short duration, they make a brilliant spot in 
the border when they do bloom. The equally attractive 
black pods which follow the flowers, and the grayish wax- 
like foliage make the plants desirable until frost. The- 
emg varieties are B. australis, blue, and B. tinctoria, yel- 
ow. When in bloom, the height of the plant is about 3 feet. 
Boltonia.—This is known also as the false chamomile or 
false starwort. It is an aster-like plant that would combine 
well with Aster tataricus as a background for the perennial 
border. Three species are worthy of mention, namely, B. 
latisquama, lavender, B. asteroides, white, and B. latisguama 
nana, pink. The two former are 6 feet high, while the latter 
is only 2 feet in height. 
Campanula.—tIncluded in this genus are the plants com- 
monly known as Canterbury bells, bell-flowers, cup-and- 
saucer plants, etc. The eee species grown loca ten 
C. Medvum (Canterbury bell), and its variety calycanthema 
(cup-and-saucer). A less common variety is C. pyramidilis, 
which is a much taller plant and may be had in blue or white. 
Like the aquilegias, campanulas seem to thrive better in par- 
tial shade. This is especially true in the case of C. Medium, 
wilting and decay taking pee when the plant is left in the 
hot sun after a rain. When grown in shady locations or 
under conditions of even temperature, however, a diseased 
plant is seldom seen. After transplanting, a whole season’s 
growth is required before flowering can take place, and when 
raised from seed two or more years is necessary. 
Cassia Medsgeri.i—This plant, commonly known as the 
senna, is found growing wild in Missouri. It attains a height 
of 5 to 6 feet and produces masses of oer pea-like flowers 
in August, which are followed by black seed pods in the fall.
