THE XURSERY-LIST 225 



Akebia. Lardizabalacece. 



Propagated by seeds, layers of young or ripe wood, cuttings 

 of green or hard wood under glass in summer. Roots are sometimes 

 divided. 



Albizzia. Leguminosas. 



Propagation as for acacia, which see. The species usually seed 

 freely. 



Alchemilla (Lady's Mantle). Rosaceoe. 



Propagated by seed, and by division of the clumps. 



Aleurites. Euphorbiacece. 



Propagated by mature cuttings in sand, under glass. Leaves 

 should not be removed. May also be grown readily from seeds. 



Allamanda. Apocynaceae. 



Propagation is sometimes by layers. Cuttings of the shoots root 

 well at any time of the year, but spring is usually preferred, as the 

 plants then attain good size before winter. Either old or new 

 wood may be used. Old wood is cut to two or three joints, being 

 taken in spring or late winter from the annual pruning of the plant. 

 Young wood is cut with a heel. Cuttings should be struck in 

 sandy soil in a propagating-box, at a temperature of about 70. 

 Sometimes the cuttings are started in pots. 



Allium (Onion, and onion-like plants grown for ornament). 



Liliacece. 



Easily increased by seeds sown thinly in light soil in early spring. 

 Also propagated by offsets and by bulbels, planting them in autumn 

 or spring 1 to 4 inches deep. See Onion, Leek, Chives, Garlic. 



Alloplectus. Gesneriacece. 



Propagation as for gesneriads, page 318. 



Almonds (Pr units communis, P. japonica, P. glandulosa, P. triloba, 



and others). Rosaceas. 



The details of propagating the fruit-bearing (nut-bearing) 

 almonds (Prunus communis or P. Amygdalus) do not differ materi- 

 ally from those followed in propagating the peach and apricot. 

 Almond seedlings make the best stocks when the soil conditions 

 are favorable, both sweet and bitter almonds being used. When 

 the soil moisture conditions vary widely or where the soil lacks 

 depth or is otherwise at fault, peach seedlings are perhaps prefer-
