ROCK GARDEN PLANTS 
ARTHUR LEE NURSERIES 
ACHILLEA. Yarrow; Milfoil. 
These are showy perennials for rock gardens and perennial borders, some of which are useful for 
cut flowers. Some have silvery and others finely cut foliage which adds much to the appearance 
of the plant. 
Culture: The Achilleas are good subjects for dry soils and sunny places. A too rich soil 
should be avoided. As nearly all grow very freely, it is advisable to lift, divide and replant 
every two years. When plants have finished blooming they should be cut down. 
Millefolium roseum. fS.L.)

front of shrubs or in border, li ft. June to Sept.

flower variety, li ft. June to Sept.

ACONITUM. Monkshood. 
These bloom during the late summer and fall and can be 
relied upon to furnish the desirable blue in the gar¬ 
den when the Delphiniums have past their best. Lovely 
plants of stately growth particularly suited for shady 
or half shady borders, woodland gardens and by the^ 
waterside. 
Culture: Aconitums will grow well in any good soil, 
providing that it is fairly moist. They do best when 
they are growing in a shady or semi-shady location. 
May also be naturalized in the wild or woodland garden 
or on the margins of water. It is not advisable td 
disturb the plants frequently as they display their 
beauty to best advantage when they have become well 
established and formed large clumps.
