The Late Red Honeysuckle, Z. p. serotinum , is simply a late 
variety with darker flowers, and very showy during its blooming. 
The Dutch Honeysuckle, Z. p. belgicum , differs from the 
first only in being more shrubby. 
The Yellow-flowered Honeysuckle, P. plava, is a native 
of our States, half hardy, with large ovate leaves nearly joined at 
the base, and bright yellow flowers in June and July. 
The Trumpet Honeysuckles. Z. sempervirens. — Indigenous, 
and sub-evergreen at the south. Flowers scarlet, and borne 
throughout the summer season after May. The H. s. superba and 
H. s. Browni are superior varieties. 
The Chinese or Japan Monthly Honeysuckles. Z. jcipon- 
ica. —Sub-evergreen, and not quite hardy; but of robust growth, 
densely clothed with leaves, constantly in bloom and deliciously 
fragrant, and of course universally popular. Protection is so easily 
given them that their slight unhardiness is a small objection to their 
use. The varieties are very numerous. Among them is the Gold- 
veined-leaved sort, L. j. folks aui'ea reticulata , the leaves of which 
are exquisitely veined with gold lines, each leaf as pretty as a 
blossom, making it one of the most interesting to plant in porches 
or verandas among the darker leaved sorts. A moderate grower. 
The Evergreen Ivy. Hedera. 
“ Creeping where no light is seen, 
A rare old plant is the ivy green.” 
“ The common evergreen ivy is a rooting climber; but when 
these roots are opposed by a hard substance which they cannot 
penetrate, they dilate and attach themselves to it, by close pres¬ 
sure on the rough particles of its surface.” Unless, however, 
the surface presents some crevices into which roots can penetrate 
a little, the plant cannot sustain itself on a wall by the mere 
adhesion of its root-mouths against it; in other words, it cannot 
sustain itself on a hard and smooth stone surface. In this respect 
it is neither stronger nor weaker than our Virginia creeper. The 
evergreen ivy can hardly be said to have become domesticated 
in this country. Our summers are too hot and dry, and our 
winters too cold for it; and it rarely clothes lofty walls with
