THE NURSERY-LIST 349 



Ligustrum (Privet. Prim). Oleaceoe. 



Propagated by seeds sown in fall or stratified ; and by division. 

 Seeds may not germinate the first year. The named varieties 

 are usually grown under glass from cuttings of green or ripe 

 wood, and are sometimes grafted on L. vulgare or L. ovalifolium. 



Liliaceae. Liliads. 



Nearly all liliaceous plants seed freely. Some produce small 

 bulblets on the flower-stems. Others are propagated by dividing 

 the bulbs. The strong growing lilies with thick scaly bulbs may 

 be increased by stripping off the scales and planting them as cut- 

 tings. The seeds of hardy kinds may be sown out-of-doors in 

 April or May. The seeds of tender sorts may be sown as soon as 

 ripe in a greenhouse with a temperature of 60 to 70. Many of 

 the liliaceous plants are propagated by offsets, but the larger number 

 may be increased by seeds. 



Lilium (Lily). Liliacece. 



The usual propagation of the true lilies is by offsets from the 

 bulbs, but seeds may be employed for the production of new varie- 

 ties. With a few species, blooming bulbs may be had the second 

 season after seeds are sown, but usually three to five or even six 

 years are required. Seeds commonly germinate within a month or 

 two if sown in autumn when fresh, but dried seeds may lie dormant 

 much longer. Seeds of some species do not germinate till the first 

 or second spring. Lily seeds are usually sown about inch 

 deep under moss in boxes of sand and kept under glass till they 

 germinate ; then out-of-doors protected from direct sun. 



Usually lilies are increased by bulbels, which should be planted a 

 few inches apart in prepared beds. The offsets or bulbels are 

 taken about the time seeds would ripen, as the roots are most 

 dormant then ; in two or three years blooming bulbs should be 

 secured if the offsets are taken good care of in well-prepared beds. 

 Sometimes small bulblets form in the axils of the leaves, and these 

 are used in the same way as bulbels. Bulb-scales are often em- 

 ployed for the multiplication of scarce kinds, giving blooming 

 bulbs in two or three years. Those that produce large and loose 

 bulbs, as L. candidum, may be increased by simple division. 

 These operations are described on pages 57 and 58. 



Lily-of-the-Valley : Convallaria.
