This eBook from the Gutenberg Project consists of approximately 154 pages of information about Hardy Ornamental Flowering Trees and Shrubs.

C. MAS.—­Cornelian Cherry.  Austria, 1596.  One of our earliest flowering trees, the clusters of yellow blooms being produced in mild seasons by the middle of February.  It is not at all fastidious about soil, thriving well in that of very opposite description.  It deserves to be extensively cultivated, if only for the profusion of brightly-tinted flowers, which completely cover the shoots before the leaves have appeared.  C. Mas aurea-elegantissima, the tricolor-leaved Dogwood, is a strikingly ornamental shrub, with green leaves encircled with a golden band, the whole being suffused with a faint pinky tinge.  It is of more slender growth than the species, and a very desirable acquisition to any collection of hardy ornamental shrubs.  C. Mas argenteo-variegata is another pretty shrub, the leaves being margined with clear white.

C. NUTTALLII grows to fully 50 feet in height, and is one of the most beautiful of the Oregon and Californian forest trees.  The flower bracts are of large size, often 6 inches across, the individual bracts being broad and white, and fully 2-1/2 inches long.

C. OFFICINALIS is a Japanese species, that is, however, quite hardy in this country, and nearly resembles the better known C. Mas, but from which it may at once be known by the tufts of brownish hairs that are present in the axils of the principal leaf veins.

C. STOLONIFERA.—­Red Osier Dogwood.  North America, 1741.  This has rather inconspicuous flowers, that are succeeded by whitish fruit, and is of greatest value for the ruddy tint of the young shoots.  It grows fully 6 feet high, and increases rapidly by underground suckers.  The species is quite hardy.

C. TARTARICA (syn C. siberica).—­Siberia, 1824.  This has much brighter coloured bark, and is of neater and dwarfer habit, than the typical C. alba.  It is a very beautiful and valuable shrub, of which there is a variegated leaved form.

COROKIA.

COROKIA COTONEASTER.—­New Zealand, 1876.  A curious, dwarf-growing shrub, with small, bright yellow, starry flowers produced in June.  The hardiness of the shrub is rather doubtful.

CORONILLA.

CORONILLA EMERUS.—­Scorpion Senna.  France, 1596.  This shrub, a native of the middle and southern parts of Europe, forms an elegant loose bush about 5 feet high, with smooth, pinnate, sub-evergreen leaves, and Pea-shaped flowers, that are reddish in the bud state, but bright yellow when fully expanded.  It is an elegant plant, and on account of its bearing hard cutting back, is well suited for ornamental hedge formation; but however used the effect is good, the distinct foliage and showy flowers making it a general favourite with planters.  It will thrive in very poor soil, but prefers a light rich loam.

CORYLOPSIS.

CORYLOPSIS HIMALAYANA.—­E.  Himalayas, 1879.  This is a stronger growing species than C. pauciflora and C. spicata, with large leaves averaging 4 inches long, that are light green above and silky on the under sides.  The parallel veins of the leaves are very pronounced, while the leaf-stalks, as indeed the young twigs too, are covered with a hairy pubescence.
