THALICTRUM—Meadow-Rue 
Hardy perennials, with elegant, finely divided. Colum¬ 
bine or Maidenhair-like foliage, which is most useful 
for cutting for mixing with cut flowers. Are borne in 
feathery clusters or panicles, and they add considerably 
to the beauty of the plants. They are of easy cultiva¬ 
tion in sun or shade. 
Culture. They will thrive in any good, ordinary, well 
drained soil. May be grown in sunny or partially shaded 
borders. Tall species like aquilegifolium are most ef¬ 
fective when grown as single specimens in the front 
of shrubbery borders, or in the wild garden. The other 
species may be grown in colonies in the garden or bor¬ 
der. Plant in autumn or spring, 8 to 12 inches apart. 
Dipterocarpum should be carefully protected if planted 
in the fall.

their drooping, tubular flowers in dense spikes on long,

are much prized for cutting in late summer and early 
autumn. 
Culture. Any good, ordinary, well drained soil and a 
sunny position will suit Tritomas. Plant in spring only, 
12 inches apart. A liberal mulching of decayed manure 
should be spread around the base of the plants in early
