give many heads before the second year. A quicker and 

 bettermethod of propagation is to use the suckers, which 

 are freely produced about the crown. The suckers repro- 

 duce the variety. The Artichoke is little known in Amer- 

 ica, but is worthy greater attention. The habit of propa- 

 gating by seed is, perhaps, one reason why the Artichoke 

 has not "obtained greater prominence in this country. 

 The great woolly, pinnatifid Ivs. and strong habit make 

 the plant an attractive ornamental subject. See Cardoon.

 ARTICHOKE, JERUSALEM (Helidnthus tuberdstts, 

 Linn.). Compos it<e. While the Globe Artichoke is sel- 

 dom seen in American gardens or on American tables, 

 and surely not appreciated by our people, the Jerusalem 

 Artichoke is so common as to be despised as a weed. 

 The Jerusalem Artichoke is the tuber of a perennial sun- 

 flower-like plant. ( Fig. 14.'). ) It thrives on almost any 

 drained land, without much attention as to manuring, 



and without coddliiis;. Tin- tul.rrs may 1 ut to single 



eyes and planted lik..- .•..mni.ni pi.tato.-^. The cultivation 

 is about the same as that ii^uailv i,'ivfu in (M»rn or pota- 

 toes. Anytime in the fall alter frost has killed the tops, 

 or the latter have matured, the crop can be gathered. 

 Pull up the whole plant by the roots, or dig the tubers 

 with a potato hook or prong hoe. Or, swine may be turned 

 into the field and allowed to root up and feed on the 

 tubers. All kinds of farm animals seem to be fond of 

 them. They may be ground and fed, mixed with grouml 

 grains, to poultry 

 with good results. 

 As a succulent food 

 for cattle, sheep, 

 swine, and perhaps 

 other farm stock, this 

 tuber seems to de- 

 serve more general 

 attention on the part 

 of the American 

 farmer than it has 

 ' ~ "*" usually received. It 



is far ahead of the potato in productiveness, and much 

 more cheaply grown. Raw or boiled and served with 

 vinegar, the tuber also makes a very good winter or 

 spring salad, and for this purpose it may find a limited 

 sale in our markets. The chief demand for it will be 

 for seed purposes. The easiest way of keeping the crop 

 over winter is by leaving the tubers io the ground

where they grew, as they are not hurt by frost when 

 covered with soil. Tubers already gathered can be 

 pitted like beets or turnips, but will need even less cover- 

 ing of soil. The Mammoth White French is said by some 

 propagators to be an improved strain of the ordinary or 

 Jerusalem Artichoke. The plant often becomes a weed ; 

 but hogs will root it out. The plant is native to upper 

 Canada and middle parts of the U. S. It was cult, by the 

 Indians. See Helianthus. t. Gbeiner.

Arum (ancient name). Aroideee. Tuber-bearing low- 

 herbs, of few species, in Eu. and W. Asia. Lvs. simple, 

 the petiole sheathed at the base : spathe convolute, va- 

 riously colored, mostly including the short spadix : pis- 

 tillate fls. at the base. Grown usually as oddities, mostly 

 under the general name of Callas. Some of the species 

 are hardy ; others, as A. Pakestinum, are tender, and 

 require glasshouse treatment. The tender kinds are 

 managed in essentially the same way as the fancy -leaved 

 Caladiunis. Plant the tubers sufiSciently deep that roots 

 may fnriii frnni mar the top. Give rich soil, and water 

 freelv wli.ii ^.-niwim,' or in bloom. The hardv species 

 shouid 1.1' well mulflied in late fall. They thrive best in 

 partially shaded places and in rich soil. Prop, by nat- 

 ural offsets ; also by seeds or berries, which some spe- 

 cies produce freely. Some of the species are acrid- 

 poisonous. Monogr. by Engler in DeCandoUe's Mono-
