124 Subtropical Gardening. 



remain on for a long time in spring and early summer. 

 It generally grows from 12 ins. to 16 ins. high, forming 

 thick, almost pyramidal, tufts of pale green, glaucescent, 

 deeply-divided leaves, and bearing handsome drooping 

 clusters of large, rose-coloured flowers, often flowering 

 twice in the year. Although not absolutely necessary, it 

 will be all the better to plant it in light soil. Multiplied 

 by division of the tufts in spring. It should be associated 

 with dwarf subjects like Thalidrum minus, or be used on 

 the margins of mixed beds of fine-leaved hardy plants. 



*Dimorphanthus mandschurieus. — A magnificent 

 hardy shrub of erect habit, with very large, much-divided, 

 spiny leaves, which very much resemble those of the 

 Angelica-tree of North America, and in this country at- 

 taining a height of 6 ft. to 10 ft., which it will probably 

 much exceed when well established in favourable positions. 

 It is certainly the most remarkable fine-foliage shrub 

 that has been introduced into our gardens for years, and 

 is therefore of the highest importance for the subtropical 

 garden. As to its treatment, it seems to thrive with the 

 greatest vigour in a well-drained deep loam, and would 

 grow well in ordinary garden soil. As to position, isola- 

 tion in some sheltered but sunny spot will show it to 

 great advantage ; but it may also be grouped with like 

 subjects, always allowing space for the spread of its great 

 leaves. 



*Dipsacus sylvestris. — A rather singular-looking 

 hardy native plant, 5 ft. to 6 ft. high, with a prickly, leafy, 

 branching stem, and longish opposite leaves joined 

 together at their bases. The flowers are of a pretty 

 purplish rose-colour, and are borne in conical heads 3 ins.
