flowers.

*Stachys lanata. IT oolly Betony. 1 ft. July. A very useful plant for edging 
because of its dense, attractive, silvery white foliage which is particularly 
effective in showing off the small, delicately tinted, purple flowers.

ing plant, with very large, lavender-blue flowers resembling the Centaureas.

exceptionally satisfactory. 35c each; $3.50 per doz.; $22.00 per 100.

main attractive throughout the whole season. The showy part of the flowers 
is usually the long, threadlike stamens which are very delicately colored, 
giving a most airy, foamlike quality to the bloom. Beautiful either as speci¬ 
mens or masses, but they look best in masses at the edge of shrubs or at the 
center or rear of the borders, depending upon the height of the varieties 
chosen. 
Thalictrum aquilegifolium. Columbine Meadowrue. 3 ft. May to July. 
A very graceful border plant with heads of feathery cream-colored flowers.

plant with bright yellow, pea-shaped blossoms like yellow Lupines and 
bright green, clover-like foliage. The merit of this splendid native has 
never been fully appreciated. Fine for wild garden or half-shady places in 
the shrubbery, but it is even better introduced among the lighter shades of 
Delphiniums, making an interesting and striking contrast with them.

Tradescantia virginiana. Virginia Spiderwort. 2 ft. July, August. An old 
garden plant, with grasslike foliage and violet-blue flowers.
