tempts to transplant them. The seedlings, too, make only one growth 
in the season and so increase slowly. It is therefore doubtful if the 
spread of this plant will be as rapid in American gardens as was hoped 
a few years ago when it was first brought to this country. 
Rhododendron (Azalea) yedcense var. poukhanense, which is the 
first Azalea in the Arboretum to open its flower-buds, has been in full 
bloom for several days on Azalea Path where there is a large mass of 
these plants. This is a very hardy shrub widely distributed in Korea 
from the neighborhood of Seoul southward, and grows generally in open 
Pine-woods and on grass-covered slopes where it forms dense mats 
rarely more than three feet high, although in more sheltered shaded 
positions it is occasionally as much as six feet tall. Here in the Arbor- 
etum in full exposure to the sun it forms dense mat-like bushes from 
two to two and a half feet tall and three feet or more in diameter. 
This Azalea is perfectly hardy in the Arboretum where it first flowered 
in 1914. The flowers are clustered, with a rose or rosy purple corolla, 
and are more fragrant than those of any other Azalea in the Arbore- 
tum collection. On Azalea Path these Korean Azaleas are growing 
close to plants of Fothergiila major and F. monticola which are now 
also in bloom, and the snow white flowers of the Fothergillas contrast- 
ing delightfully with the rose-colored flowers of the Azaleas suggest a 
good color scheme for the spring garden. 
Early-flowering Viburnums. The first Viburnum to bloom in the Ar- 
boretum this year is Viburnum alnifolium, the Hobblebush or Moose- 
wood of cold, wet northern woods. It is a large shrub spreading by 
shoots from the roots, with broad flat clusters of small flowers sur- 
rounded by a ring of large pure white neutral flowers, dark green leaves 
with prominent veins, which turn orange and scarlet in the autumn, 
and fruit in drooping clusters, bright red at first when fully grown and 
dark blue or nearly black at maturity. This is one of the handsomest 
of the American Viburnums but it has proved a difficult plant to estab- 
lish here, although in other Massachusetts gardens it has grown better 
than it has in the Arboretum, where, however, it at last appears to 
have become accustomed to its surroundings. Another Viburnum is in 
flower in the group of these plants near the upper end of the Bussey 
Hill Road and on Hickory Path near Centre Street. This is the Korean 
Viburnum Carlesii and one of the hardiest and n;ost beautiful shrubs 
which the gardens of America have obtained from eastern Asia. Its 
greatest value is found in the white waxy flowers which are arranged 
in small, very compact, nearly globose clusters and open from rose- 
colored buds. As the flowers do not all open at once the buds among 
the white flowers add to the beauty and interest of the flower-clusters 
in early spring. The flowers of no other Viburnum and of few other 
hardy plants are as fragrant as those of Viburnum Carlesii. It is a 
plant which should be in every northern garden. Unfortunately seeds 
are produced rarely in this country. It has suffered, too, from the fact 
that Japanese nurserymen have for several years sent to this country 
as this species a Japanese plant called Viburnum bitchuense which is 
in every way inferior as a garden plant. This Viburnum is also in 
flower near V. Carlesii in the Viburnum group.
