BEDDING PLANTS.

and viscosissima, are extremely beautiful, their dense corymbs of 
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 varie¬ 
ties are of the shrubby class, the latter is herbaceous, the flower- 
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. jloribunda 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. corymhosa 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 and 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 C. 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 strict a. 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 coccmea and lithospermoides are both showy plants, 
on account of the bright scarlet of their bracts; they should be
