Kahi.y-flowehing Dieuvillas ok Weigelas. The ear¬ 
liest of these pants to tlower in the Arhoretuin, and per¬ 
haps the handsomest of all the species, varieties and hy- 
l)i‘ids of Diervilla known in gardens, is the Korean form 
of 1). florida discovered and introduced hy Mr. Jack to 
which the varietal name vemisld has hc(Mi given. It is 
already a shrub here live feet tall and three or four feet 
through, and every spring is comphdely covered with 
d(‘nse clusters of rosy-pink dowers from an inch and a 
half to two inches in length. It is |)erlectly hardy, 
w hich cannot he said of all the garden Weigelas; it grows 
i-apidly, and no shrubs can hear larg('r crops of dowers.
