358 List of Shrubs 
Three other species, C. glaucus Willd. (153), C. levigatus Willd. 
(154), and C. occidentalis Hook and Arn. (155), are scarcely as hardy and 
have few superior points, except perhaps difference in color intensity. 
Caragana, see Trees [List B]. 
Carpinus, see Trees [List C]. 
Chionanthus, see Trees [List C]. 
Comptonia, see Myrica. 
Celastrus. Bitier-sweet. This genus of some twenty-five species, 
native from Asia and Australia, furnishes several low shrubs of a trail- 
ing or climbing habit which makes them invaluable for effective cover- 
ing of rocks, trellis, or posts. Their bright varicolored fruit, hanging 
on through the winter, makes them even attractive at that monotone 
season. They are most adaptive, filling any soil and situation, sun or 
shade. Suckering freely, they can be readily propagated or renovated. 
C. scandens Linn. (155 bis) is our native species, common from 
Canada to New Mexico, climbing to twenty feet, the crimson seeds 
in the opening orange-yellow capsules continuing through the winter. 
C. orbiculatus Thunb. (articulatus) (155 tres), from Japan and China, 
does not differ much from the former, but appears more prolific in foli- 
age and fruit, which latter, however, is hidden under the foliage until 
the fall. 
Corylus. Hazelnut. C. Americana Walt. (156), the American species, 
has but little ornamental value, yet is picturesque and is useful for 
planting along watercourses and other wet or moist, but also in dry 
places. 
C. Avellana Linn. purpurea (157), a variety of the European species, 
four to six feet high, fit for dry as well as moist situations, excels by its 
large, round, dark purple, almost black foliage, preserving its color 
even better than the blood beech, changing to lighter hues in the fall. 
There is also a very ornamental variety, lacimtaia (1570), with deeply 
cut leaves. Neither of them are more than half hardy at Ottawa. 
Crape Myrtle, see Lagerstroemia. 
Currant, see Ribes. 
Daphne. Of the forty or more species and varieties, widely dis- 
tributed throughout the south temperate zone, at least three deserve 
notice as being among the finest low shrubs for use in borders, massing 
for color effect by foliage, flower, and fruit, and especially in rock work 
and for refined planting. They are adaptive and shade-enduring.
