E. purpureum {Trumpet Weed). — A 

 N. American species 3-9 ft. high or more. 

 Leaves 3-6 in a whorl, somewhat ovate 

 or lance-shaped, pointed, roughish, un- 

 equally toothed, downy beneath. Flow- 

 ers in autumn, purplish, in corymbs. 

 Grown in rich soil and in bold masses, 

 this species has a very bold effect in the

LIATRIS (Snakekoot). — This genus 

 contains about 16 species of perennial 

 herbs, all natives of N. America. Leaves 

 alternate or scattered, narrow, entire, 1-5- 

 nerved. P'lower-heads purplish or white, 

 spicate, racemose, or panicled. Bracts 

 of the involucre small, imbricated, in 

 many rows. Beceptacles naked. Pappus 

 feathery. 



Culture and Propagation. — When 

 grown in masses these plants are very 

 effective in the flower border with their 

 long dense spikes of flowers. It may be 

 remarked that the flower-heads of these 

 plants usually open from the top of the 

 spikes downwards, and not from the 

 bottom upwards as found in most other 

 plants. They thrive in ordinary garden 

 soil, and may be readily increased by 

 division of the roots in spring ; or by seeds 

 sown as soon as ripe in the aixtumn in 

 cold frames, afterwards pricking out the 

 seedhngs and growing on until about the 

 end of May, when they may be planted 

 out. 



L. elegans. — An elegant plant 2-4 ft. 

 high, with smooth, spotted leaves ; lower 

 ones spoon-shaped, 3-5-nerved ; upper 

 ones strap-shaped, short, sometimes 

 spiny-tipped. Flowers in summer and 

 autumn, purplish, in spikes a foot or more 

 long. 



Culture dc. as above. Easily increased 

 by division in spring. 



L. graminifolia. — A tuberous-rooted 

 species with pointed, remotely dotted 

 leaves, fringed at the base. Flowers in 

 autumn, purple, loosely spicate, in the 

 axUs of the upper leaves or bracts.

 upright spikes of rather large heads of 

 flowers, with the bracts of the involucre 



narrower and thinner than in the type. 

 The variety pilosa has very narrow 

 involucre bracts. 



Culture dc. as above.

 summer and autumn, pale purple, in 

 dense cyhndrioal spikes 1-1^ ft. long. 



Culture dc. as above. This is best 

 treated as a biennial. It grows well on 

 dry soUs, and the seeds may be sown in 

 cold frames in autumn, and the seedlings 

 transferred to the open ground in mild 

 showery weather about the end of April 

 or May.

 with very long and narrow leaves, and

 ft. high, with lance-shaped acute leaves, 

 ciliated at the base. Flowers in Sep- 

 tember, purple, in spikes 6-15 in. long.

 high. Lower leaves long, i in. wide, 3-5- 

 nerved ; upper ones strap-shaped, stif&sh. 

 Flowers in summer and autumn, bright
