TO THE FLOWER GARDEN, 271 



The tubers must, be potted in sand, loam, with a third of leaf- 

 mould, and placed in the greenhouse in the full light. This 

 is best done about February ; but they sometimes commence 

 growth in autumn, and, if so, must not be checked. As tliey 

 send up their thread-like shoots provision must be made for 

 their support by placing a trellis, over which the stems are 

 to be from time to time carefully trained. The plants will 

 require air and a moderate supply of water ; and after they 

 have fairly begun to grow, and before they are trellised, they 

 should be placed in the pot they are to fill, which, if the tuber 

 is a strong one, should be not less than ten or twelve inches 

 across. T.pentaphyHum is hardy if planted deep in light rich 

 soil in a sheltered place, such as near a wall ; and T. speciosum 

 may be similarly treated, and is very beautiful. These two 

 are now referred to Chymocarpus. There is another group 

 containing several ornamental species — tender perennial 

 plants, without tuberous roots, mostly blooming in winter, 

 and requiring to be often renewed from cuttings. Of this 

 T. Lohbianum is an example. It must be kept in mind that 

 they all require plenty of air, moderate but careful watering, 

 plenty of drainage, and watchfulness, as the shoots grow, to 

 place them as they should grow upon the trellis, otherwise 

 shoots will twine round each other, instead of distributing 

 themselves properly on the wirework ; and when they once 

 get matted it is verv difficult to untwine and release them.

TULIPA. Tulip. [Liliacese.j Hardy and very showy 

 bulbs. The variegated Tulips of the gardens are the progeny 

 of T. Gesneriana : these flowers are grown in collections, and 

 have a noble effect. The bulbs are planted in October or 

 November, shoot above ground in February, and bloom iu 

 May. They grow in nothing so well as in plain good sandy 

 loam, taken from a pasture with the turf rotted in it ; and it 

 is the custom to dig out the bed from two to three feet deep, 

 that this soil may be placed therein. They are planted six 

 inches apart, the bed being four feet wide, and containing 

 seven flowers across. The tallest flowers, which are known 

 well to the fanciers, are planted in the centre row ; those a 

 little shorter in the rows next to the middle ; and the shortest
