VIBURNUMS AND OTHER SHRUBS AND TREES AT THE 
ARNOLD ARBORETUM IN EARLY JUNE. 
\ ilturnums have Ixm'ii largely jtlanted in llie Arbor¬ 
etum and the abundant and eonspienons How (‘rs now 
open on st'vei’al of the speeit's show th(‘ value of tbe.se 
])Iants lor the deeoi'ation of jtarks and gardens. Vibur¬ 
nums are found in all the tempt'rate parts of the nortbern 
bemispliere, the largest number of species growing in 
eastern Asia and in the easbUTi United States. The (‘ast¬ 
ern American species, all things considered, are more val¬ 
uable garden jtlants than those from other jtarts of the 
w orld, although there are a few Old World species which 
must Jte counted among the h(‘st of all hardy shrubs. 
Among these Old World sp(‘cies which cannot he spared 
front our collections are the European Wayfaring-tree, 
Vihurmnn Ldntdua, the Jajtanese and (ihinese U. tomen- 
losum, and the .Japanese V. (Ulalaium. The first of these 
plants is a large shrub or small tre(‘ with blue-green 
foliage, large conv(^x clirsters of flow(‘i's which ar(‘ fol¬ 
lowed by fruits, which when fully grown are at first 
bright red and then Itecome black, fruits of the twa) colors 
being found together in the same cluster. This is a very 
hardy and vigorous ])lant and flowers here early in May. 
Viburnum tomenlosum is a large flat-topped shrub w ith 
w ide-spirading horizontal branches, and in .laitan some¬ 
times h(‘comes tn^elike in habit. It is one of the species 
in which the clusters of small perfect flowers are sur- 
lOLinded by a ring of abortive flow ers w ith much (‘iilarg- 
ed pun; white corollas. The flower clusters of Vibur¬ 
num fomentosum an' arrang(‘d along the up[)er side of 
the branches and are ()ioduc(‘d in gn'at |)rofusion. mak¬ 
ing it one of the most laxuitiful of all the shrubs now' 
flow ering in tin' Arboretum. The fruit is small, at first 
bright red and finally nearly hlaek; the leav(‘s turn 
orange and red in the autumn. A varic'ty of this j)lant 
with very narrow leaves (var. lanrcolulum) diseov(‘red 
by Professor Sargent in .laj)an is flowering in tin' ivcent- 
!y aiT’anged Vihinnum (Iroup on tin' right-hand side of 
the Jfuss('y Hill Road near its junction with tin' Valh'y 
Hoad. The Japain'se Snowball, know n usually in gar- 
d('ns as Viburnum pUruluni, is a form of Viburnum lo- 
mentosinn (yav, dilulafum) . This must not he confound¬ 
ed, how('vei', with tin' Inn' Viburnum dilulufum, which 
w ill not he in flowa'r probably for a cou|)le of w('eks. This 
is a large shrub w ith nunn'rous clusl('rs of creamy w hil(' 
flowers hut is most int('i'('sting in tin' antuiim wln'ii it is 
covered with small, bright red, lustrous fruits which r('- 
main in good condition for a long tinn'. 
Of tin' thiee spc'cies cnltivalf'd in the Arhoia'Imn of 
the Opulus (Ironp of Vihnrniims, with ])almat('ly lohed 
and veined leaves and showy sti'i ih' flowa'rs snrromnling 
the flower cluslei-s, two art' from tin' Old Woi'ld and art^ 
j)erha])S handsomer garden plajds than the American rep- 
lesentative of this gronj). Tin' thit'c sjx'cies are E. ojiul- 
us, fi’oni ceidral and nortln'rn Europe. J'. Surf/enlii, from 
northeastern Asia, and J'. (unericunum, from north¬ 
eastern America. Tin? first is the largest |)lanl of 
the three, wuth thicker dark('r grt't'n leaves late p('rsisl('nt 
in the autumn, and daik red fruit. The old-fashioin'd 
Snowltall of gardens is a form of this sjtt'cies w ith all the 
flowers stei'ile; there Is a very dwarf form which rara'ly 
flowers, and there is a form w ith yellow fruit. 'Hn' flow¬ 
ers of Vibiniium Sunjimlii art' mort' showy than I host' of 
tin' other species, hnl tin' fruit is small and incon¬ 
spicuous. The habit of V. umrrirunum, tin' so-callt'd 
Iligh-l)ush Uranherry, is less comitact than that of tin' 
other spt'cit's. The flowers, howevt'r, are heaulifnl. and 
the fruit, w hich Is transinct'nt and very In.strous. rt'inains 
on the branches through Hit' winter; in the antnnm Hit' 
leavt's turn bright orangt'-rt'tl Ix'fort' falling. Tin' thret' 
species art' all very hardy. Vilmrnum amerirunum and 
V. Surf/enlii have been gt'nerally planted in the Arhor- 
t'tnm, and very largt' plants of J'. opufus can ht' st't'ii on 
the Parkway and in somt' of tin' otht'r Boston |)arks. 
Among the other Amt'rican spt'cit's Viburnum ulni- 
folium, the Ilohhle-hnsh. and I', prunifolium havt' al- 
rt'ady llowert'tl. Tin' s|)t'cit‘s which is now so 
conspicuous in many jtarls of tin' .Vhort'Inm is tin' .Nan¬ 
ny-berry, U. lenluf/o. This common Nt'w England I'oatl- 
sidt' plant is a largt' shrub or small Irt't' w ith lai'gt'. thick, 
lust rous It'avt's. largt'. ronntit'd clnslt'is of t'rt'amy w hilt' 
flowers which are followed by drooping hlue-hlack fruits.
