MOouNTAIN FLEECE, see Polygonum. 
MounTAIN FEATHER FLEECE (Stenanthium robustum). 5-8 ft. A 
very beautiful hardy perennial with long lily leaves and panicles of 
feathery, drooping white flowers often 2-3 ft. long. As the flowers 
ripen they turn to shades of pink and purple. Requires a deep, rich, 
moist soil; propagate by seeds or offsets. 
Putox. Perennial (Phlox paniculata, var. F. G. Von Lassburg). 
4 ft. Though there are many white varieties, this is said to be the best 
white Phlox under cultivation, bearing great heads of pure white 
flowers. It requires a deep, rich soil, sun and much water during the 
flowering season, also a top-dressing of manure during summer. If the 
tops are pinched off when plants are about a foot high, they will make 
a lower more bushy growth, and the flowers will be more numerous, 
though smaller. They will also be a little later in blooming. By pinch- 
ing off only a portion of the plants, or the outside stalks, it will retard 
the bloom of certain ones and thus prolong the season of bloom. Propa- 
gated by seed or division of the root in spring or autumn. The latter 
method is the surest way to perpetuate any given strain. It can also be 
increased by cutting a strong root in pieces and treating it as you would 
seeds; also cuttings taken from roots of old plants grow easily, and 
cuttings from shoots that will not bloom that season are used. Seed, 
if sown early in heat, then hardened and planted out in May, will bloom 
the first season; by this latter method new varieties are secured, as they 
cross easily. White Phlox is particularly beautiful planted with Golden 
Glow, Helianthus or Stokesia Cartesia. Also many shades of pink, red, 
lilac and blue; see other lists. 
Potyconum. Mountain Fleece (P. amplexicaule). 2-3 ft. Has a 
strong, woody rootstock, flowers creamy-white in one or two racemes 
from 2-6 in. long. Give partial shade and any good soil; inclined to 
spring up over the garden. Propagate by division; needs a little protec- 
tion in severe winters. Blooms very late in August or early September. 
Also a deep red variety. 
SNAKEROOT. White (Eupatoriwm ageratoides). 3 ft. A native plant 
in some portions of the North and Middle West, but very desirable 
under cultivation. It is of erect, leafy growth with thin green leaves 
and large heads of finely-divided white flowers. Give a rich moist soil; 
propagated by division of root.
