HELIOTROPIUM.

In summer they should be placed in any open part 
of the Garden, and the pots plunged in the ground to 
prevent the sun from scorching their roots, and repot¬ 
ted whenever their roots become much matted round 
the sides of the pot. The soil most suitable for them 
is good black peat, and sandy loam. They are apt to 
be troubled with the scaly insect, which should be 
brushed or rubbed off with a flat stick, and the plants 
washed with soapy water, and then syringed with 
clean water. Young plants may be grown to a good 
size by planting them out of their pots in the spring, 
in a bed of sandy loam and peat, and as their roots 
are very fibrous, they can be taken up with good balls 
and potted before frost, and placed in the Green¬ 
house. 
They are propagated by taking off young cuttings 
and planting them in pots filled with sand and covered 
with a glass, which should be placed on the front shelf 
of the Greenhouse, and shaded from the sun. Keep 
the sand a little moist, and when the plants are rooted, 
they may be potted in small pots, and treated as old 
plants. 
HELIOTROPIUM, (peruvianum and corymbosum.) 
The Heliotrope is a fine plant, much admired for 
its fragrance, and being a native of Peru, it requires 
a strong heat to flower freely, which makes it a desi¬ 
rable plant for warm rooms, and if sufficient attention 
is given to it, it will flower nearly all the year round,
