HARDY WOODY PLANTS 155 



varieties should be chosen having clinging disks. This species is especially at- 

 tractive for its fine autumn colors. 



Ampelopsis tricuspidata, Japanese Creeper. Coninionly called Boston Ivy. 

 This is a very satisfactory climber, especially on brick, stone, or stucco vi'alls. 

 It thrives better on eastern and northern walls, though it can often be grown 

 with satisfaction on '.vestern or even southern exposures. It is rather slow 

 getting started but requires no particular care after once established. 



Aralia spinosa, Devils-walkingstick. A big, coarse, rather showy plant, 

 perfectly hardy and fit for use where coarse textures or striking effects are 

 desirable. Produces abundance of small white flowers in large clusters and 

 especially attractive in fruit. 



Aristolochia sipho, Dutchmans-pipe. This favorite old climber has been 

 growing on the campus since the beginning and is entirely hardy and satis- 

 factory. It is rather too heavy for ordinarj' porch use, but can be used on 

 lattice screens and other places where support is available. It is hardy, clean, 

 and free from insect or disease attack. 



Aronia atropurpurea, Purple Chokeberry. A dwarf native shrub rather 

 interesting and attractive for jjlanting along woodland borders and in other 

 naturalistic compositions. 



Aronia melanocarpa, Black Chokeberry. Another native species similar to 

 the foregoing and equally satisfactory for general planting. 



Azalea nudiflora, Pinxterbloom. Sometimes also called Swamp Pink. A 

 beautiful native ericaceous plant suitable for the finer sorts of landscape 

 plantings. Good nursery-grown plants are always to be recommended above 

 native plants taken from the field. 



Azalea rosea, Downy Pinxterbloom. Another of the native azaleas, pre- 

 ferring a somewhat drier situation than either nudiflora or viscosa. Its pink 

 flowers with their very pleasant odor make it a valuable addition to this group 

 of shrubs. 



Azalea viscosa. Swamp Azalea. Somewhat similar to the foregoing and 

 entirely satisfactory for permanent planting; somewhat more adapted to 

 swampy, wet land. 



Baccharis halimifolia, Groundselbush. This rather insignificant native sea- 

 side shrub has been occasionally used on the grounds but has no special merit 

 for local conditions. 



Berberis thunbergi, Japanese Barberry. Extensively used on the college 

 campus for many years for hedges, foundation plantings, and for positions 

 requiring hardy shrubs to withstand rough use. The plant is so convenient 

 and so thoroughly adapted to a number of diverse uses that there is always 

 danger of vulgarizing it. Propagates readily from seed. Handles well under 

 the shears but looks better when left to its natural habit of growth. 



The variety with variegated leaves {Berberis thunbergi variegata, some- 

 times called Silver Beauty- Barberry) has also been grown on the grounds 

 but has nothing nmch to recommend it. 



Berberis vulgaris, European Barberry*. A hardy shrub widely disseminated 

 and to some extent naturalized throughout this region. Satisfactory for growth 

 in the shade, for large rough hedges, and for a variety of common practical 

 uses. Propagates readily from seed.
