EUCALYPTUS 
Eucalvptus trees thrive so well in California 
and such large specimens can be seen that many 
believe them indigenous. This is incorrect, as 
thev are all from the Australian region. Each 
year sees a wider planting of Eucalyptus, and we 
doubt if it can be carried too far. In spite of 
the extremely rapid growth of most kinds, the 
wood is mainly hard and strong; in fact, many 
species surpass even Hickory in this respect. 
Some yield valuable oils, others are desirable for 
Their flowers. Those wishing more detailed in¬ 
formation regarding the commercial species are 
advised to procure Bulletin Xo. 196 of the Agri¬ 
cultural Experiment Station, University of Cali¬ 
fornia, Berkeley. Unless otherwise specified, the 
following form large trees. It will be noted, 
however, that some arc comparatively dwarf. 
E alpina 12 ft. Makes only a shrub. Leaves 
very short and oblique at base. Flowers white. 
Useful as a large shrub. 
E. amygdalina angustifolia (E. linearis). One of 
the most beautiful on account of its graceful habit, 
dense foliage and remarkably narrow, light green 
leaves. Flowers white. 
E angulosa (E. incrassata angulosa). 25 ft. Small 
tree with short, blunt leaves. Flowers white. 
Named from the ridges or angles on seed capsule. 
E. bicolor (E. largiflorens) . BLACK BOX. 25 ft. 
Shrub or small tree with drooping branches and 
persistent bark. Leaves of medium length. Wood 
hard, tough and durable in or out of ground. 
E calophylla. 20 ft. Growth and foliage about 
Mke E. ficifolia, but not wavy margined. Flowers 
usually white, occasionally pink, very large. Thrives 
well in coast district. Very hardy. 
E. citriodora (E. maculata citriodora). LEMON- 
SCENTED GUM. Tree of rapid, erect growth. 
When young, leaves are rough, hairy and without 
stalks; when tree is older, they are stalked, very 
smooth and curved. Foliage is strongly impreg¬ 
nated with lemon scent. Flowers creamy white. 
The trunk sheds its bark every year during its 
blooming period, leaving it milky white and abso¬ 
lutely smooth. Has the peculiarity of developing 
most of its branches toward the prevailing wind. 
Very sensitive to frost when young. 
E. coriacea (E. pauciflora). WHITE GUM. 
Rather tall tret* with spreading branches and slen- 
Eucalyptus globulus com pacta 
Bushy Blue Gum 
* 
Eucalyptus leucoxylon (Red-flowering) 
See page 28 
der twigs. Outer bark strips. Leaves long. Flow¬ 
ers white. One of the hardiest. 
E. corynocalyx. SUGAR GUM. An excellent 
species, attaining good size. Bark strips, lias two 
forms of leaves. Very resistant to drought and hot, 
dry winds. Timber strong and durable, especially 
in the ground, not likely to warp, and resistant to 
ants and insects. 
E. di versicolor (E. colossea). KARRI. Very 
large, tall tree with smooth, white bark. Leaves 
dark green and glossy. Does best toward the coast 
Has beautiful red, hard, durable wood, taking a 
high polish. 
E. ficifolia. SCARLET-FLOWERING GUM. Con¬ 
trary to the habits of most Eucalyptus, this species 
is dwarf and of slow growth. Leaves large, leath¬ 
ery, pointed, wavy-margined, dark green. Flowers 
very large and normally crimson or scarlet, but 
vary considerably, sometimes appearing pink or 
orange. Has the handsomest flowers of all. 
E. globulus. BLUE GUM. By far the most 
widely planted species in this country. Growth 
exceedingly rapid, probably more so than of any 
other known tree. Old leaves long and tapering. 
Flowers yellowish white. Has a white, hard, close- 
grained wood of great strength, now being used in 
preference to oak and hickory where their qualities 
are demanded. Not good for posts, etc., as it soon 
decays in the ground. Admirable for fuel, as it 
will renew itself continually from sprouts after 
being cut. Succeeds in a great variety of soils and 
conditions, but not well adapted to particularly 
drv ground. Endures about 10 degrees of frost. 
Foliage is used to obtain eucalyptus oil. Except 
where actual experiment has shown other species 
to be better, this is the safest one by far for gen¬ 
eral planting. 
E. globulus compacta. BUSHY BLUE GUM. A 
very distinct and valuable variety introduced by 
this Company. With no pruning whatever, it forms 
a symmetrical, rounded, compact tree. It does not 
form any main trunk and the branches are indefi¬ 
nitely divided, giving a solid mass of foliage from 
the ground to top. Lower foliage is like that on 
young growth of common Blue Gum, but consider¬ 
ably smaller and even more silvery. When five or 
six years old it commences to develop the longer, 
narrow leaves toward the top. It makes a fine 
single specimen and is also, beyond any doubt, the 
most efficient wind break that can be planted in 
California.
