[45] JARNOLDIAA continuation of theBULLETIN OF POPULAR INFORMATIONof the Arnold Arboretum, Harvard UniversityVOLUME 4 DF.CEMBER 8, 1944 NUMBERS 9-11 IAVAILABLE RAPID GROVfIN(~ VINES FOR THE UNITED STATESVINES play a very essential part in any garden, and rapid growing vines arefrequently desired for some particular purpose which no other plant materialwill fulfill. Sometimes they are needed only temporarily; other times they areneeded permanently. Rapid growing ines are not always the most ornamental,but, since their number is rather large, some of the best will be found amongthem. Nor are the most ornamental vines always the easiest to obtain. Rapidgrowing vines that are easily obtainable are very much of interest and are in de-mand throughout the country. Consequently, this number of Arnoldia deals withthose rapid growing vines, easily obtainable, that are recommended in differentareas of the C’nited States. They may not all be of prime ornamental value when<·ompared with some of the rarer ones, but their rapid habit of growth makesthem of considerable value for certain screening purposes.The information in this issue of Arnoldia is taken from a report prepared ashort time ago when there was a great deal of interest in the camouflaging ofvarious installations in this country, both public and private. Various horticul-turists’t mndely separated parts of the country contributed information on the* Edgar Anderson, Missouri Botanical Garden, St. Louis, MissouriW. H.

It must be understood that all of the vigorous and fast grow-ing vines do not appear in the following lists, merely because some are very dif-ficult to find in nurseries and are of more or less restricted occurrence in nature.AreasFor purposes of selecting the right vines for the right areas, the United Stateshas been divided into eleven general areas, and vines are listed and recommendedfor each area. Naturally, these areas will overlap considerably. It is readily un-derstood that there are many places within a certam area, where, because of al-titude, soil conditions, or some climatic factor, recommended vines may not thrive.For instance, Area No. 1-the Eastern United States-bounded by the AtlanticOcean, Canada, the Mississippi River, and a line across southern Mississippi,Alabama, and Georgia-covers a great territory with widely varying climatic con-ditions. Vines that would not grow in the vicinity of 11t. Washington in NewEngland would flourish in the comparatively mild climate of the James River mVirginia. With these points in mind, the recommended areas for growing thesevines should be taken with considerable reserve. The most vigorous and mosthardy vines only have been selected. All can be used for screenuxa purposes.Vines for growing within specific localities should be selected after first obtainingavailable information concerning plant growth and hardiness m the specific lo-cality under consideration.1. Eastern and Northeastern United States-In ",.eneral all that part of theUmted States east of the Mississippi River and between lower Georgia, Alabama,Mississippi and Canada.2. North Central United States-The entire area in Wiscowin, ()hut, Indiana,the Chicago area, and possibly west of the Mississippi into Iowa. (Areas 1, and3 overlap somewhat, but much of the recommended plant material is ~dentic·al.)3. Central United States-Inoludin~ a wide area around Missouri, Arkansas,Oklahoma. In general, this area has summers that are more hot and dry than inthe eastern United States.4. The Great Plains Area-Incluclin~; a wide area around Minnesota, Nebraska,North and South Dakota, Kansas, Montana, Wyoming. However, in northernMontana, Wyoming, and North Dakota, temperatures go extremely low in thewinter and some of these vines may not survive in the areas with extreme wintercold.5. Northwest Pacific Coast-Between San Francisco and Seattle. Many of thevines can be used considerably farther inland than the coastal area.6. San Francisco Area-This is intermediate between Areas :5 and 7. Many ofthe vines recommended for growing in both these areas will grow in the vicinityof San Francisco, some, however, needing special care.477. Southern California-This does not include the hot, arid areas.8. Semi-arid area of Southwest Texas9. Coastal Area of Southern and Southwestern United States-This includespart of Texas and a general area across all the Gulf states through Florida butdoes not include the subtropical areas of Texas and Florida.10. Extreme Southern Texas and Southern Florida-Subtropical areas only.There is a small area, south of Corpus Christi, which can be considered as sub-tropical, together wrth the southern part of Florida.11. Extreme southern part of Florida-Many of the vines listed in area 10 canbe grown throughout southern Florida but there is an area from Stuart southaround the coast to Ft. Myers, where truly tropical vines can be grown.VINES FOR EASTERN AND NORTHEASTERN UNITED STATES(Area 1 )Clinging to stone or wood by rootlets I,omcera japonica HallianaCampsis radicans Lonicera sempervirensHedera Helix Menispermum canadenseParthenocissus quinquefolia Polygonum AubertiParthenocissus tricuspidata Pueraria Thunher~ianaWisteria floribundaClimbing by tendrils or twisting leaf Wisteria sinensisstalks (These will cling to any mate- n Isterla SInenSISrial similar to chicken wire.)
