are smaller plants from the southern coast region and require especial

Every one in New England interested in gardens knows the brilliant 
autumn colors of the Japanese Berberis Thunbergii which has been 
much planted here in recent years and is now an extremely popular 
garden shrub. Some other Asiatic Barberries, although still little 
known here, are equally beautiful at this season of the year. The 
dwarf form of Berberis Thunbergii (var. microphylla ), of dwarfer habit 
and smaller leaves, which originated in the Arboretum several years 
ago, is an attractive little plant, and a Japanese variety of the species 
(var. Maximowiczii) is a larger plant than the type, with arching stems, 
larger leaves and larger flowers and fruits. In the autumn the color of 
the leaves is as beautiful as those of Berberis Thunbergii. But probably 
the handsomest of all the Barberries which are hardy in this climate is 
the Japanese Berberis Regeliana. This is a large shrub with the habit of 
the common Barberry, but the leaves are larger and more lustrous, the 
fragrant flowers are larger and of rather a paler shade of yellow, and 
the fruit is more brilliant; in the autumn the leaves turn orange and 
scarlet. This Barberry was among the first of the Japanese shrubs 
brought into American gardens as it was cultivated at the Parsons’ Nur- 
sery on Long Island fully fifty years ago and was then known and dis- 
tributed as Berberis Hakodate. It appears, however, to be still very 
rare in the United States and Europe. There is a large clump of this 
species among the Barberries on Hickory Path near Centre Street. 
Another Japanese Barberry, Berberis Sieboldii , is well worth a place 
in every collection for the beauty of its deep dull red autumn foliage. 
This is a smaller shrub with erect stems forming a round-topped head, 
large flowers in few-flowered clusters, and large shining fruits. 
There is now a large number of new Chinese species of Barberry in the 
Arboretum but the value of many of these as garden plants here is not 
known. Two Chinese species, Berberis diaphana and B. dictyophylla 
which were discovered a few years ago by French Missionaries who sent 
them to France whence they reached the Arboretum, are now known to 
be plants of exceptional value. Berberis diaphana is a low round shrub 
with solitary pale yellow flowers which are followed by large red fruits. 
The habit of this plant is unusual among Barberries and make it valu- 
able in small shrubberies. Its greatest beauty, however, is in the au- 
tumn color of the leaves which is not surpassed in brilliancy by that 
of any other Barberry. Berberis dictyophylla is a tall shrub with slen- 
der erect stems which form an open irregular head, small spiny leaves 
which are light green on the upper surface and silvery white below, 
large pale yellow flowers solitary or in pairs and red fruit. This shrub 
is attractive throughout the season and is particularly beautiful in the 
late autumn when the upper side of the leaves turns scarlet and the 
lower side retains its silver color, a condition which is found in a few 
other plants and is always attractive. These Barberries are established 
in the Shrub Collection and can be found in the supplementary Barberry 
collection on Hickory Path. 
The Arboretum will be grateful for any publicity 
given these Bulletins.
