BUCKEYE 
This genus (Aesoulus) includes trees of all sizes 
from semi-shrubs to forest giants. The immense compound 
leaves and the interesting branching make them very sat- 
isfactory garden subjects. They are easy to transplant, 
grow rather rapidly, have comparatively few pests, and 
are not too particular about the soil. However, they do 
have faults. Some individuals and some varieties shed 
their leaves in midsummer and remain bare for the rest of 
the season. All of them produce a fruit of considerable 
size, and the old hulls, plus the large leaves, may make 
lawn maintenance difficult. Every member of the genus 
produces enormous quantities of flowers on large panicles, 
and in the case of an old tree, the ground beneath may be 
covered as the flowers mature and fall. It is one of the 
few trees having a wide range of color. The native semi- 
shrub (Aes cuius Pavia) produces scarlet flowers, while 
the Ohio Buckeye (i. Octandra) has yellow flowers. Some 
of the hybrids developed as ornamentals have various 
shades of pink and yellow flowers. 
BUCKTHORN 
The plants belonging to this genus (Sumelia) are all 
very slow growing, but at the same time, they are all 
very long lived. When planted on good sites, the native 
species, the Wooly Buckthorn (£. Lanuginosa), grows into 
a small round-headed tree with contorted branches. The 
leaves are spatula shaped, and clothed with white hair 
underneath, thus giving the tree a whitish-green cast. 
The plant should be more widely used as a hedge in the 
Middle West. It is unusual in its ability to grow on dry 
situations, and a Buckthorn hedge will require no irriga- 
tion in a Missouri summer 
CATALPA 
This tree, so widely planted at one time, has com- 
pletely lost its popularity due to a number. of bad 
habits. As a lawn tree, the dropping of the immense 
leaves make it difficult to keep the garden tidy. The 
flowers are produced so profusely that when they fall, 
they cover the ground. In fall, the ripening of the fool 
long seed pods presents still another problem in mainten- 
ance. The tree, as a whole, is not subject to much stor 
breakage even, though the wood is very light-weight. Tne
