ASTILBE 



wlit'n fiiiiugation is necessary. Aphis, spider or thrips 

 never trouble Astilbe. As a border plant, Astilbe is one 

 of the hardiest of our hardy herbaceous plants ; but the 

 feathery plume obtained in the greenhouse is much 

 shorter, more compact, and lacks the pure whiteness of 

 the outdoor-grown specimens. William Scott.

 country, but hardy in the 

 open. There are various

 cle more compact ; var. 

 muItiJlbra, Hort. ; var. va- 

 rieg4ta, Hort., with varie- 



geted Ivs.; var. purpdrea, Hort., with purple-shaded 

 foliage. Astilbe Japonica is often confused with Arun- 

 cus astilboides ; Figs. 169 and 170 will aid in distin- 

 guishing them.

A genus of over 1,000 spe- 

 cies of hardy herbs or 

 subshrubs. Lvs. mostly 

 odd-pinnate: fls. in spikes 

 or racemes, yellow, purple 

 or white. They prefer a 

 light, porous soil and no 

 shade. The dwarfcr kinds 

 may be placed in the front 

 of the border or in the 

 rockery. Prop, chiefly by 

 seeds, which germinate 

 slowly, or slowly by careful 

 division in early' .spring. 

 Many kinds are likely to 

 die if divided or trans- 

 planted. Many kinds are 

 cultivated in the Old 

 World, but the four de- 

 scribed below are the only 

 kinds commonly sold in 

 America. Of the many na- 

 tive kinds, mostly known 

 as rattle-weeds, the following are ad- 

 vertised at present: A. Canadenni.i = 

 A. Carolinianus, A. cari/occrrpits, A. 

 Drummondii, A. fleruosus, A. Lax- 

 A. Parrifi, A. racemoitus, A. 

 'i, A. Shortianus. The Loco- 

 weed of the prairies, which is said to 

 poison cattle, is A. mollissimus. For 

 these and many others the student is 

 referred to Britton and Brown's Illus- 

 trated Flora, and Coulter's Manual of 

 Rocky Mountain Botany.
