Rosa VVichuraiana was named after the German botanist Wichura, 
who accompanied the German expedition to China and Japan in 
1859-61. He died in 1866. The Rose came to England about 1890 
by way of the United States, where it had already become popular 
and was largely grown, notably in the PTanklin Park, Boston, where 
it was employed with great success in covering banks and rocky slopes. 
It had been sent from Berlin by Louis Spath in 1888 to the Arnold 
Arboretum as Rosa bracteata, Imt proved to be Rosa IVic/uiraiana 
of Crepin, who first called attention to its distinctive characters in 
1886. At that date it was already in cultivation at Munich and 
Brussels. 1 1 had previously been confounded with Rosa L^tciae F ranch. 
& Rochebr., and still earlier with Rosa sempevvirens L. Although in 
a dried state it is difficult to distinmiish Rosa WicJiitraiana from some
