The shepherdia argentea is an ornamental shrub of value for 
planting in situations where it is safe to employ a silvery leaved 
small tree. 
SPIRAEA.—We feel disposed to modify our former unfavorable 
reports on the spiraeas. No shrub on our grounds has attracted 
more attention this spring than Van Houtii’s spiraea. The plant 
was for days a mass of white bloom. This spiraea was grown 
without irrigation. Most of the other species need an artificial 
supply of water here. 
PHILADELPHUS.—There is much confusion in the nomenclature of 
the different species of Philadelphus as supplied by the average 
nurserymen. This confusion is added to by careless people who 
apply the name syringa to the Philadelphus, instead of to the THES; 
where it properly belongs. 
The common mock orange, Philadelphus coronarius, was the first 
to bloom with us. It does not seem to be quite so hardy as some of 
the other kinds. Philadelphus grandiflorus is very satisfactory 
with us. A closely related variety or, possibly, species is one brought 
by Prof. Budd from Russia and numbered by him 144 Veronesh. 
At the present writing it is the most striking shrub on our grounds 
—a grand mass of beautiful white bloom. A species brought from 
an Eastern nursery some years ago under the name of Philadelphus 
cordatus, and which is probably Philadelphus Gordonianus, is 
about two weeks later than the other species. It suffered some dur- 
ing last winter but is going to bloom freely. By planting these 
different species one can be well supplied with the flowers of the 
mock orange for at least four weeks. 
* PHYSOCARPUS.—Physocarpus opulifolia, or nine bark, formerly 
included with the spiraeas, is very satisfactory with us. During the 
flowering season the bush is covered with umbel-like clusters of 
white flowers, and when the flowers have passed away the reddish 
fruit pods make it fully as beautiful. 
CARAGANA.—The different species and varieties of the pea shrub 
are very satisfactory with us. They are somewhat slow about get- 
ting established,but this year nearly all the species bloomed. Their 
yellow, drooping flowers in early spring are very attractive. 
AMELANCHIER.—The Juneberries are early bloomers and this year 
they were unusually attractive. They were unaffected by thespring 
frosts and are bearing a heavy crop of fruit. Lovett’s Success Is 
doing the best with us. 
Morus.—The Russian mulberry passed through last winter with- 
out very serious injury, but the frosts of May struck it, and it is not 
producing its usual amount of fruit. 
SYRINGA.—The common lilac. Syringa vulgaris is one of the 
hardiest shrubs ever planted in western Minnesota. There ought to 
be hedges of it on every farm. Small root sprouts of this lilac set 
out on the open prairie a year ago,along with box elder, survived the 
drought and the winter, where even the box elder was completely 
root-killed. The white variety is fully as hardy. The Persian lilac 
(Syringa Persica) comes into bloom at an earlier age than the com- 
mon lilac. It is perfectly hardy and desirable. Syringa Josikaea is 
doing well here, but has not yet bloomed. A variety of the common
