52 BULBS AND TUBEROUS-ROOTED PLANTS. 
purple or white. For general cultivation they are worth- 
less, the beauty of the flowers not being worth the care 
and attention it costs to produce them. 
CAMASSIA. 
A small genus of hardy bulbs common in some of 
the Western States, and closely allied to Scilla, or Squill. 
They are entirely hardy, and can be rapidly increased by 
division, or from seed. 
C. esculenta.—The more common species some- 
what resembles the common blue hyacinth, but is much 
larger. The leaves are about a foot long, very narrow, 
and grooved through the center. ‘The flower-stalks 
grow from one to two feet high, and bear large, showy 
purple flowers. The roots of this species were largely 
employed as food by the Indians, the various tribes visit-

for the species is Quamash. It is well worth cultivating. 
The only Eastern species is C. /rasert, or Wild Hyacinth, 
which is not cultivated. 
CANNA., 
Indian Shot. 
Although the Canna is not a bulb, it is always asso- 
ciated with bulbs. It would seem out of place anywhere 
else, and a list of bulbs would appear incomplete without 
it, as would any collection of ornamental plants. But 
few plants are better known than the Cannas, and few 
less appreciated. Because of the free-growing habit, 
thriving under almost any circumstances, they are gen- 
erally grown without care and in a manner that does not, 
in any degree, develop their beauty or usefulness. To 
have Cannas in perfection, the soil must be worked deep 
and made very rich. They are gross feeders, and enjoy 
moisture in proportion. Although a swamp plant, it
