BULLETIN NO. 24. 
Next to the Lilacs the most conspicuous shrubs now in the Arboretum 
will be found in the group of Bush Honeysuckles. Among these are 
some of the hardiest and generally most successful shrubs for northern 
gardens. They not only produce countless beautiful and fragrant flowers 
but their fruits, which usually ripen in summer, are equally beautiful and 
abundant. The best known of these plants, the Tartarian Honeysuckle 
( Lonicera tatarica), a native of the region from southern Russia to the 
Altai and Ural Mountains, is an old inhabitant of gardens where formerly 
it was more often seen than it is at present. This is a vigorous plant, 
growing ten feet high or more and equally broad, and there are varieties 
with white, pale yellow, pink and rose-colored flowers, and with yellow 
and red fruits. Interesting and valuable hybrids of this plant have ap- 
peared in European gardens. One of the handsomest of these, L. notha, 
with pale pink flowers, is believed to be the result of a cross with 
L. Ruprechtiana from northeastern Asia. There are two large speci- 
mens of this plant on the right-hand side of the Bussey Hill Road oppo- 
site the Lilac Group. There is here also a large plant of L. bella, with 
pale yellow flowers, the result of a cross between L. tatarica and L. Mor- 
rowii. L. xylosteoides, with white flowers, a hybrid between the Tarta- 
rian Honeysuckle and L. Xylosteum, and L. muendeniensis with pale 
yellow flowers, a hybrid of the Tartarian Honeysuckle with L. Morrowii 
from northeastern Asia, are also handsome and desirable plants. 
Other interesting plants now in flower are L. muscaviensis, with pale 
yellow flowers, a hybrid between two species of northeastern Asia, 
L. Morrowii and L. Ruprechtiana, L. Segreziensis , with white flowers, a 
hybrid between L. quinquelocularis and L. Xylosteum, L. multiflora with 
white flowers, a hybrid between L. micrantha and L. Morrowii. The 
translucent fruit of this plant is perhaps the most beautiful of all the 
Honeysuckle fruits produced in the Arboretum. Lonicera Korolkowii 
is a vigorous plant from Turkestan with pale bluish foliage and small 
rose-colored flowers; equally beautiful are the var. floribunda of this 
species and a hybrid of the species with L. tatarica which appeared in 
the Arboretum and is known as L. amoena Arnoldiana. These three 
plants are of exceptional value from the beauty of their delicate flowers 
and foliage. 
Attention is also called to three Honeysuckles from northeastern Asia, 
L. Ruprechtiana with narrow leaves and large yellow flowers, L. 
Maackii with pure white flowers, and L. Morrowii with white and yellow 
flowers. The flowers of L. Maackii are large and make a handsome con- 
trast with the dark green leaves. The form of this species from west- 
ern China, var. podocarpa, is in every way a less desirable garden plant. 
L. Morrowii is a large, round-headed shrub with pale, gray-green foliage 
and wide-spreading branches, the lowest clinging close to the ground. 
This plant is well suited for the formation of dense thickets or to border 
drives and walks where abundant space can be given to it, as can be seen 
at several points in the Boston Park System. A hybrid between 
L. Morrowii and L. tatarica is often sold in American nurseries as 
L. Morrowii itself, but it is a very inferior plant to either of its parents.
