When growth commences in spring, which will generally be early in March, give each plant its final shift into eight-or ten-inch pots.  This must be done before the buds push up, or there will be more foliage than flowers.

The following is the compost we advise:  one bushel good yellow loam, half-bushel leaf-soil, one gallon silver sand, a pound of Sutton’s A 1 Garden Manure, and a pint of soot, well mixed at least ten days before use.  Any sourness in the soil will be fatal to flowering.  The compost must be carefully ‘firmed’ into the pots, but no severe pressure should be employed, or the roots will not run freely.

Neglect as to temperature or humidity will have to be paid for in long joints, green fly, red spider, or in some other way.  But there are no plants of high quality that grow more thriftily if protected from cold winds and kept perfectly clean.  A light airy greenhouse is their proper place, and they must have ample headroom.

After the pots are filled with roots, not before, manure water may be administered until the flower-heads begin to show colour, when pure soft water only should be used.  About a fortnight in advance of the full display the branches must be tied to supports.  If skilfully managed the supports will not be visible.

It may be that a few large specimens are required.  If so, shift the most promising plants into 6-size pots.  These large Calceolarias will need regular supplies of liquid manure until the bloom is well up, and if the pots are efficiently drained and the plants in a thriving condition, a rather strong beverage will suit them.  For all ordinary purposes, however, plants may be allowed to flower in eight-or ten-inch pots, and for these one shift after the winter is sufficient.

==New Types of Calceolaria.==—­There are now available a number of hybrid half-hardy perennial varieties, of which =C. profusa= (=Clibrani=) is the most popular, that bear the same relation to the Large-flowered Calceolaria as the Star Cineraria does to the Florist’s Cineraria.  In point of size the blooms produced by these new types are smaller than those of the Large-flowered section, but the tall graceful sprays are extremely beautiful and of the greatest decorative value.  Except that seed should be sown earlier (February and March are the proper months), the plants should receive precisely the same treatment as that already described for Herbaceous Calceolaria.

Notwithstanding the ease with which cuttings of the Shrubby Calceolaria can be carried through a severe winter, there is a growing disposition to obtain the required number of plants from seed sown in February; and seedlings have the advantage of great variety of colour.  A frame or greenhouse, and the most ordinary treatment, will suffice to insure a large stock of attractive healthy plants for the embellishment of beds and borders.
