310 MANUAL OF GARDENING 
ginia creeper. Grapes are admirable, particularly some of the 
wild ones. Japan honeysuckle is much used; and it has the 
advantage of holding its foliage well into the winter, or even 
all winter southward. Actinidia, akebia, wistaria, roses, dutch- 
man’s pipe, and clematis are to be recommended; the large- 
flowered clematises, however, are more valuable for their bloom 
than for their foliage (C. paniculata, and the native species are 
better for covering porches). 
The annual vines are mostly used as flower-garden subjects, 
as the sweet pea, morning-glories, mina, moonflowers, cypress 
vine, nasturtiums, cobea, scarlet runner. Several species of 
convolvulus, closely allied to the common morning-glory, have 
now enriched our lists. For baskets and vases the maurandia 
and the different kinds of thunbergias are excellent. 
The moonflowers are very popular in the South, where the 
seasons are long enough to allow them to develop to perfection. 
In the North they must be started early (it is a good plan to 
soak or notch the seeds) and be given a warm exposure and good 
soil (see in Chap. VIII).
