Although late importations of plants have greatly enriched our stoves and 
greenhouses, they have contained few things capable of existing in the open garden 
except during summer. Hence, a novelty with the line characters of our subject, 
will be the more highly appreciated. It is a novelty interesting to all parties, 
whether possessed of a greenhouse or not ; since it will brave our severest winters, 
and demands little attention or skill in its culture. 
It was first discovered by the lamented and indefatigable Douglas, in his 
explorations of the north-west coast of America, about the Columbia and the 
Straits of Fuca; but was not introduced to this country by him. Within the last 
five years a few plants were reared in the Glasgow Botanic Garden, from seeds 
sent to the Curator, Mr. Stewart Murray, by Dr. Tolmie, who gathered them at 
Fort Vancouver. Blossoms were produced by these plants, for the first time, 
about two years ago. 
Not the least interesting quality of the species is the long period during which 
it continues to produce flowers. Our drawing was made at Messrs. Low and Co.'s 
nursery, Clapton, from a specimen which flowered last July ; and we have since 
received specimens from Mr. Murray, who, in a letter addressed to us some time 
since, states that " one of its recommendations is, that after the flowers of all other 
shrubs have passed, it is found in perfection. Last year it was fine even when the 
frost came on in October." 
It makes a handsome bush, much like the S. tomentosa, ultimately reaching a 
height of four or five feet ; but it blooms at a much smaller size, and by layering
