THE YARROWS. 



2or 



out Europe and Asia from Spain to Java, 

 and commonest from the Balkan region 

 and north-east Africa, through Asia Mi- 

 nor to Persia. Only those kinds of some 

 value from the garden point of view are 

 given here: — 



Greek Mountain Yarrow (A. agerati- 

 folid). — A silvery-leaved plant from the sub- 

 alpine districts of northern Greece, with large 

 white flowers like Daisies, carried singly upon 

 stems of 6 or 8 inches, early in summer. The 

 leaves are narrow, tongue-shaped, crimped, and 

 covered with white down. This is a very neat 

 and distinct plant, thriving in light soil. Syn. 

 A.ageratoides ; also known as Anthemis Aizoon. 



Silvery Yarrow [A. argentea). — A neat 

 and attractive kind, effective from its pretty sil- 

 very foliage growing in compact tufts of a few 

 inches, with numerous heads of pure white 

 flowers in June and July. Asia Minor. Division. 

 This plant is now often classed in the allied 

 group of Tanacetum. 



Alpine Yarrow [A. alpina). — An old 

 European plant, first described bv Linnaeusbut 

 almost unknown in cultivation, though excel- 

 lent in the rock-garden for its good habit and 

 loose heads of silvery-white flowers. 



Asplenium-leaved Yarrow [A. aspleni- 

 folid). — One of the few American kinds, grow- 

 ing 1 8 inches high, with deeplv-cut leaves and 

 dense heads of small flowers of white or rose 

 colour, from June until the autumn. 



Black-cupped Yarrow (A. atratd). — A 

 pretty alpine kind from the mountains of Aus- 

 tria, forming a low tuft of deep green aromatic 

 leaves, with white flowers in August. 



White Alpine Yarrow [A. Clavennce). — 

 Adwarf plant of striking appearance with leaves 

 deeply jagged and covered with a short, silky 

 down of silvery white ; clear white flowers in 

 summer. It thrives in a light, free soil, often 

 dyingout in heavy ground, and isa prettyplant 

 for the rock-garden or borders, effective when 

 massed with such dark-leaved plants as Trifo- 

 lium rubrum or Ajuga purpurea. Alps of Austria. 

 Division and seed. 



Saw-leaved Yarrow [A. decolorans) . — A 

 distinct Swiss plant of about 15 inches, with 

 white hairy leaves regularly toothed, andflower- 

 heads of good clear white. The double-flowered 



form of this species comes very near A. Ptar- 

 mica plena,but differs from it in its more deeply 

 serratedleavesand more rigid habit, and though 

 useful for cutting is yet hardly so free in flower 

 or so good as the Double Sneezewort. Syn. A. 

 serrata plena. 



The Noble Yarrow (A. jilipenaulind) 

 A handsome, vigorous perennial, well known 

 in gardens. It is of good habit, about 4 feet 

 high, with large flat heads of yellow flowers, 

 often 5 inches across, coming from July to Sep- 

 tember and retaining their beauty for a long 

 time. Excellent for groups in shrubbery or 

 border, and useful for cutting. Though often 

 described as a taller form of this plant, A.Eupa- 

 torium is no longer considered as distinct. 



Large-leaved Yarrow [A. grandifoltd). 

 — A bold plant of robust growth for the wild 

 garden, where, in rich soil, it grows 5 or 6 feet, 

 bearing fine foliage and large heads of creamy 

 white or pale yellow flowers. Asia Minor. 



Fragrant Yarrow [A. Herba-rota) . — A 

 pretty little plant growing in sunny spots upon 

 the hills of western Europe, with a pleasant 

 herb-like fragrance when touched ; low tufts 

 of undivided leaves, and loose white clusters 

 upon slender stems of about 6 inches. 



Huter's Yarrow {A. Huteri). — A plant 

 6 inches high, with greyish-green foliage and 

 pure white flowers in May and June. It likes 

 a sunny part of the rock-garden and grows well 

 in common soil. Freed from the life-struggle 

 in the alpine turf, this, like so many spreading 

 plants in our gardens, is best replanted every 

 second year. Switzerland. 



The Rosy Yarrow {A. Millefolium). — 

 Though somewhat unruly, this fine perennial 

 is worth a place for its colour in the garden dur- 

 ing July and August, growing about 2 feet high 

 and thriving in any soil upon the margins of 

 shrubberies. The best kinds are the light and 

 dark rose-coloured forms of the native plant, 

 which varies much in colour even in a wild 

 state. 



Musk Yarrow {A. moschata). — A low- 

 growing alpine plant, the leaves of which are 

 woolly and deeply cut, stems sub-shrubby, 

 flower-heads white, 4 to 6 inches high, and 

 flowering from June to August. Europe. 



Dwarf Italian Yarrow [A. nana). — A 

 very low-growing species not often met with, 

 yet a very pretty kind for the rock-garden,
