HARDY BULBS AND TUBERS.

In the third group we have lilies that require special soil, 
shade and moisture. Thus, beds of peat and leaf-mould, or 
leaf-mould only, are essential, and these should be in partial 
shade. The beds should be made between peat-loving shrubs 
in the bog garden or on the margins of a pond or lake 
where the Lily roots can get plenty of moisture in summer. 
The species that require to be grown thus are : Burbanki, 
canadense, carniolicum, pardalinum, Parryi, philadelphicum, 
Roezli, rubescens, and superbum. 
Generally speaking, all lilies are the better for having their 
bulbs and roots shaded from hot sunshine, and hence it is 
always an advantage to plant the bulbs in shrubberies or 
borders where foliage can shield the soil from the sun. 
Lilies, moreover, also show to the best effect when grouped 
or massed together, not grown singly dotted about the borders. 
It is wise, too, to plant each species and its varieties by 
itself, then the effect is more pleasing. Lilies look well 
grouped among hardy ferns or peeping here and there out of 
shrubs. 
As to planting and the time to plant. The planting may be 
done in October and November or in March. The earlier 
period is the best where home-grown bulbs can be obtained. 
The bulbs should be planted 3m. deep, each bulb being 
placed on a layer of silver sand and also surrounded by it 
before covering in with soil. In the case of imported bulbs 
examine them carefully and remove all dead scales, then 
place the bulbs in cocoanut-fibre refuse in shallow boxes for 
a few weeks to enable them to regain their normal plumpness 
before replanting. Just before planting also see that plenty 
of flowers of sulphur is freely blown into the scales of the 
imported bulbs. 
The subsequent culture of lilies is confined to giving the 
beds an annual top-dressing of decayed manure in early 
spring. This precaution is especially necessary in the case 
of stem-rooting kinds like auratum, Alexandras, Batemannias, 
Browmii, croceum, Dalhansoni, elegans, Hansoni, Henryi, 
Krameri, longiflorum, speciosum, and tigrmum, as the roots 
are greatly benefited by the manure. In dry weather, more- 
over, plenty of water is required, as lilies love moisture. An 
occasional dose of weak liquid manure will be helpful to bulbs 
that are flowering freely. So long as lilies are doing well 
do not interfere with them. When kinds like candidum fail 
to flower, lift the bulbs at the end of July and replant in a 
fresh site, then the bulbs may flower in a year or so. 
Propagation is effected by offsets removed in autumn ; by 
scales of the bulbs planted in boxes of sandy soil in a cold
