130 MISSOURI BOTANICAL GARDEN BULLETIN 
of from 6 to 8 feet. It is particularly desirable for its rapid 
growth and excellent foliage. The flowers are fragrant and 
creamy white and are borne in great profusion in May and 
June. L. fragrantissima is another creamy white variety and 
very fragrant but is a much earlier bloomer, flowering in 
April and May. 
Spiraca.—Spiraeas, or meadow-sweet, as a class, are very 
desirable garden subjects. The different varieties are quite 
unlike both in habit and in kind of flowers. They bloom 
in May and June, but even after the flowering season is over 
are worth while for their graceful masses of foliage. S. 
opulifolia, S. opulifolia aurea, 8. prunifolia, S. Reevesii, 8. 
Reevesii fl. pl., and S. Van Houttei are all white-flowered 
spiraeas and run from 6 to 8 feet in height. S. Thunbergii 
is another white-flowered variety but is only 3 to 6 feet tall, 
reigh S. colossa alba is still smaller, being 2 to 3 feet in 
eight. 
Syringa or Lilac_—Many of the white varieties of lilac are 
very attractive in early spring, but after the blooming pet 
they become miideven and have a dusty appearance. Spray- 
ing with ammoniacal copper carbonate will help this to some 
extent but they have the further disadvantage of being ir- 
regular growers and of dropping their leaves very early in 
the fall. The white lilac, if used at all, should be planted 
in backgrounds and inconspicuous places. 
Amygdalus alba.—This is commonly spoken of as the 
flowering almond and is one of the finest of the early flower- 
ing shrubs or small trees. The flowers are very showy and 
are borne in great profusion. The plants are clean growers 
and healthy in appearance. 
Cephalanthus occidentalis or Button Bush.—This shrub 
grows from 3 to 6 feet high, and is valuable for its dark green 
foliage and its peculiar globular heads of white flowers which 
bloom in July. It does well in shady and moist places. 
Clethra alnifolia.—This is known as the sweet pepper-bush. 
It grows from 4 to 6 feet high and bears masses of fragrant, 
grayish white flowers in June or July. It is a rather slow- 
growing shrub but a very desirable addition to local gardens. 
Stephanandra flexuosa.—The Stephanandra is a graceful 
shrub with spreading, drooping branches and very pleasing 
foliage qiiiol: turns purplish in the fall. The flowers are 
pure white and are borne in panicled racemes. This plant 
is not as much grown in St. Louis as it should be. 
YELLOW-FLOWERED SHRUBS 
Because yellow ar more intense against a background 
of green, it-is usually advisable to use yellow-flowered shrubs
