148 MISSOURI BOTANICAL GARDEN BULLETIN 
“ Lychnis.—This is a genus of many species but no garden 
possessing a damp spot should be lacking in L. chalcedonica. 
It has dense heads of red or scarlet flowers blooming from 
June on. A lower-growing species, L. Haageana, is about 
1 foot in height and is grown for its brilliant scarlet flowers. 
Matricaria.—The Matricaria or feverfew is closely related 
to the chrysanthemum. UM. capensis fl. pl. is an especially 
desirable variety because of its masses of double white 
flowers, and if it is cut back after the first flowering period, 
can be made to bloom continuously. 
Monarda.—This plant is called the horse-mint or berga- 
mot owing to its aromatic foliage. It is a desirable plant to 
grow, but seems to prefer moist situations. The rahe 
varieties are recommended: M. didyma rosea (rose) and M. 
os splendens (scarlet), both of which are 18 inches 
high and bloom from July to August; M. fistulosa alba 
(white), 2 feet in height; and M. Russeliana (pale blue), 
2 to 3 feet in height. 
Myosotis——This is a beautiful low-growing perennial 
commonly called the forget-me-not. It grows easily from 
seed but only does well where both soil and air are moist, 
and dries up under a hot sun. 
Oenothera or evening primrose.—This is a genus of plants 
which is most ornamental and desirable for the garden. Be- 
cause of the closing of the flowers during the day they are 
best seen in the late afternoon or early morning. O. mis- 
sourrensis, often found growing wild about St. Louis, is a 
low-growing plant 6 inches high with very large yellow 
flowers spotted with red. O. Youngii, 2 feet high, is an- 
other species very commonly grown for its large flowers. 
The plants seem to thrive exceptionally well under St. Louis 
conditions and should be used more. There are a number 
of commercial varieties. 
Paeonia.—Although St. Louis gardens are lacking in the 
charm that would come from the use of a larger variety of 
these well-known plants, it would be impossible in this short 
paper to call attention to the merits of the many species 
that may be grown in this locality. The main objection to 
paeonies, as garden plants, comes from their unsightly ap- 
pearance after the blooming period, which makes it neces- 
sary to plant annuals or perennials between them as fillers 
for the summer and fall. 
Papaver or poppy.—Attention is particularly called to the 
Oriental poppies which may be obtained in all shades of 
red and orange. The flowers are large and remind one when 
in bloom of giant tulips. Like the paeonies, they require
