TALL AND MEDIUM-SIZED PLANTS 



The species here enumerated will for the most part be- 

 come established in the wild garden and hold their own 

 against moderately strong-growing herbage provided 

 their roots are enabled to obtain a firm hold of the 

 ground without being overcrowded by native vegetation. 

 Many of them are indeed of such rampant growth that 

 even the most robust interlopers are obliged to relinquish 

 the contest defeated and in the case of less vigorous 

 subjects, which it is wished to naturalise, periodical 

 attention to their needs will generally render them 

 capable of attaining a healthful maturity. 



Acanthus. — Noble foliage plants. A. latifolius is the 

 finest species, clumps, under favourable circumstances, 

 attaining a diameter of over six feet and bearing lofty 

 flower-spikes seven feet or more in height. Its great 

 arching leaves, deeply cut and glossy are most handsome 

 and characteristic. Other less ornamental species are A. 

 spinosissimus, A. hispanicus and A. mollis. 



Achillea. — Some of the stronger-growing of this family, 

 ranging in height from two feet to four feet, are well 

 adapted to the wild garden. Amongst these may be 

 named A. Eupatorium, A. millefolium roseum and A. ptarmica 

 with its double form known as The Pearl. 



Aconitum. — Many of these may be grown, one of the 

 best being the old Monkshood, A. Napellus, which holds 

 its own amongst the coarsest vegetation and produces its 

 tall blue flower-heads freely. Other species that can be 

 employed are the yellow-flowered A. lycoctonum. A. 

 autumnale, A. chinense and A.japonicum.
