HARDY WOODY PLANTS 161 



Cydonia jnpoiiira, Flowkring Quince. A sturdy, fine, Inardy, shrub with 

 beautiful flowers in various colors, mostly red or orange, but sometimes white. 

 These selected colors may be purchased from the nurserymen. This makes an 

 attractive specimen on the grounds, is excellent in foundation plantings, and 

 on good well-drained soil makes a fine hedge. A few years ago it was threat- 

 ened witli extinction from attacks of San Jose scale, but with the subsidence 

 of this pest it is coming back into favor. 



Ci/tisus sroptirius, Scotch 15i(oo:\r. An interesting plant with slender, up- 

 right, very dark green stems and fine foliage and with bright yellow flowers 

 in early spring. Not fully hardy here, being badly killed back in severe win- 

 ters. Along the seacoast it is quite extensively used and seems to be more at 

 home there. 



Deiifzia (/racilis, Slender Deutzia. One of the best-known species in this 

 fine genus. A splendid, small, hardy, clean, thrifty shrub with good foliage 

 and especially beautiful flowers, excelled only by the following species. 



Deutzia leinoiitei, Le.^ioixe Deutzia. Much like the foregoing. Said to be 

 a hybrid but more floriferous than tlie usual species, tiie flowers being very 

 abundant, clear waxy white. Tiiis should be included in every list of orna- 

 mental shrubs, no matter how small. 



Deutzia scabra, Fuzzy Deutzia. A tall-growing (ten to twelve feet) rather 

 coarse, upright shrub, with flowers white or pinkish. Not quite so hardy as 

 the other deutzias and not so attractive to the ordinary eye. It is not com- 

 mon in cultivation. The variety Deutzia scabra plena, Pride of Rochester 

 is the best form of this species and is available from most nurseries. 



Diervilla tripda, Dwarf Busii-iioneysuckle. A small native j)lant not at 

 all consj)icuous but rather pretty in its proj)er place on the sliady borders of 

 woods. 



Dionpi/rvs vir(iliiiaiia. Co,-\i?iox Peiisi.mmo.n. This sjjecies has been planted 

 several times on tiie college campus but does not seem to l)e ])ermanent. It is 

 of no special ornamental value and being doubtfully hardy at this station 

 should not be recommended. 



Dirca palustris, Leatherwood. A fine and interesting native species. A 

 hardy, slow-growing shrul), ratlier attractive in blossom and of good foliage. 

 This .should l)e included in any collection of hardy native shrubs and would 

 be valuable for general planting except for its slow growtli and ra'her dif- 

 ficult propagation. It ])refers a moist soil and will not tolerate extreme 

 drought. 



FAaea(jnn>i atujustifolia, Ri'ssiax-olive. A tall-growing, oj)en, and irregular 

 shrub, imich resembling a gray-foliaged willow. Thougli perfectly hardy it 

 lias not proved of particular value here. It aj^pears to prefer a moist soil 

 location. 



Elaea(jiius- JoiKjipea, Cherry" Ei.aeaoxus. A good hardy shrub from Russia, 

 attractive in habit of growth and foliage, also in fruit, the fruits being edible 

 though not of high quality. This is a good reliable shrub and worth using. 



Elaeaf/nus umbellata, Autumx Elaeagnus. Somewhat similar to the fore- 

 going and having the same good qualities. The foliage more silvery- white. The 

 small, bright red fruits, much resembling red currants, are produj£»ed in 

 bunches and in great quantity and their long pcr.si.stence makes the plant a 

 striking feature in autunm.
