While not conspicuous the flowers are much admired and 
their return is always looked forward to in the spring. 
Magnolias.—To one who has the patience to wait for their 
development, no tree will give better results in a floral way 
than the magnolia. Unfortunately most varieties bloom be- 
fore the leaves open and the early flowers fall victims to the 
late frosts. However, M. acwminata, the cucumber tree, M. 
glauca, the sweet bay, and M. tripetala, the umbrella tree, 
all bloom later but are not nearly as important for their 
flowers as the early varieties. The really desirable magnolias 
for bloom are first of all, the star magnolia or M. stellata, 
then M. Yulan, both of which are white, but the former is a 
dwarf and the latter a tree-like species; M. Soulangiana for 
its large pink blooms, and then M. Lennei and M. purpurea 
for the reds. Imported magnolias usually bloom well the 
first season or so, but then rest for several years; after which 
they again begin blooming and are well worth the long wait.
