The Elegans varieties are of special value when treated as pot plants for conservatory decoration in May and June.  From seed sown in August or early in September the plants can be slowly grown into magnificent specimens four feet high and almost as much in diameter.  Our own practice is to sow thinly in clean well-drained 48-size pots.  These are placed in a temperature of from 50 deg. to 55 deg., and when the seedlings are large enough to handle they are pricked off into shallow boxes about three inches apart, the base of the boxes being freely perforated to insure ample drainage.  The most suitable soil is composed of equal parts of sound loam and leaf-mould, with the addition of a gallon of coarse sand to each bushel of the mixed soil.  After the plants are well established, ventilate freely to secure robust growth.  When three inches high pinch out the points, and a little later transfer separately to small pots, keeping them close for a few days and as near the glass as possible.  As the roots develop, transfer again to larger pots, and then the second and final stopping of the shoots must be done.  Should very large plants be wanted they can be flowered in 16-size pots, using a compost slightly heavier than that advised at a younger stage of growth.  The night temperature during winter should be about 45º, giving air freely by day whenever possible to do so with safety.  As the branches need support, sticks of a suitable length must be provided, and the stems tied out in good time to prevent them from breaking off.

==Clerodendron fallax==

==Stove shrub==

A very handsome erect shrub, which is extensively grown in tropical gardens.  In this country it attains a height of about two feet, and is easily raised from seed in a warm greenhouse or conservatory, where it proves to be a really beautiful and striking plant.

Sow in pots or pans in March or April and transfer to single pots while small.  From the commencement a very rich soil is necessary to insure robust growth and intense colour in the panicles of brilliant scarlet flowers.  The plants bloom in August or September of the same year.  When the leaves fall, if the intention be to store through winter, remove to a temperature of 55 deg.; but raising plants annually is more satisfactory and entails less trouble than storing.

Like many other tropical plants, Clerodendron fallax is subject to attack by mealy bug, and this pest may be dealt with by hand picking or by washing the leaves with insecticide two evenings in succession.  Aphis are also troublesome and should be cleared by fumigation.
