raised in about half the time it takes to mature 
the plumosus species. The seeds should be sown 
early in February and the young plants kept 
growing continuously in a temperature of 60° 
or 65°. They will be ready for planting in July. 
The soil can be prepared as for plumosus, and 
also the stringing arrangements which should be 
attended to early. It is best to replant smilax 
every year although plants can be kept over for 
two or even three seasons. 
Smilax is troubled seriously by one pest, the 
red spider, but daily syringing will check it, while 
the water will be enjoyed for its own sake by the 
plants. If syringing is begun before the insect 
appears you are liable not to see it at all. 
The long fronds of Asparagus Sprengeri are 
much valued for working in with flowers in 
interior, winter decorations. This species is 
also largely used as a pot plant, furnishing very 
attractive specimens. For cutting, the plants 
should be grown in solid beds, with conditions 
similar to those required by 4. plumosus. Since 
the vine is more of a trailer than a climber the 
stringing can be dispensed with. 
When growing 4. Sprenger in pots for house 
decoration, take care not to get the latter too large. 
The plant is a rank rooter and seems to demand
