BEDDING PLANTS.

and viscosissimci, are extremely beautiful, their dense corymbs ot 
bright yellow flowers being produced so profusely, and in such long 
succession. C. petiolaris also forms a fine object treated in the same 
manner ; it, however, requires a little additional care in supporting 
its slender panicle of blossoms, these are lemon-coloured and 
produced in the greatest abundance. The first mentioned vaiic- 
ties are of the shrubby class, the latter is herbaceous, the flowei- 
stem only rising from the ground, attaining nearly two feet in 
stature, and loaded with its pretty globular flowers; at present 
it is, we believe, rather scarce. C. jiorihunda is another desirable 
species, with straw-coloured flowers, not equal, however, either 
in colour or habit of blooming to integrifolia, which it resembles 
in growth. The varieties of C. corymbosa are also very pretty 
when treated as bedding plants, and as they embrace a wider 
range of colour, assist in making a pleasing diversity; seedling 
plants of the herbaceous varieties are to be preferred, because 
they are usually more robust. A light soil in a warm position 
is essential to the welfare of all the Calceolarias when planted 
out, and thus must not suffer from want of water. They are pro¬ 
pagated either by seeds or slips, struck ana preserved in the 
usual way. 
Campanula. There are a few species which deserve to be 
adopted for massing in large beds, such as the double Canterbury 
bells (C. medium) ; C. nobilis, when sufficiently common, will also 
make a fine object for this purpose ; the old C. pyramidalis has 
a beautiful appearance planted in quantity at the back of more 
low growing subjects of some opposite colour; and 6 . carpatica 
is an extremely useful plant, being that desirable colour, a bright 
blue, and at the same time of dwarf habit; the same may be 
said of garganica and stricta. The three first mentioned attain 
a height of from two to four feet ; they are half-hardy biennials, 
propagated by seeds or slips from the root-stock ; the remainder 
are low growing perennials, rather more tender, and therefore 
only safe in the greenhouse through the winter ; they are readily 
increased in spring by cuttings struck in a gentle heat. The 
pretty little C.pumilum and P. album are well deserving a place, 
as also is our indigenous C. rotundifolium. 
Castilleja coccinea and lithospermoides are both showy plants, 
on account of the bright scarlet of their bracts ; they should be
