Half hardy small blue labiate flowers, give a very unusual and pretty effect. 
Creepers The large Heliotrope, too, which covers so generously sometimes 
the whole wall of a conservatory, makes beautiful standards, 
and scents the whole garden. Plants, such as these, are excellent 
for filling spaces left in the borders by early summer flowers, 
and blend with the many yellow Rudbeckias and Heleniums, 
orange Montbretia, and mauve and white Asters, which belong 
to the same season. A most attractive border may be made 
with a dozen plants, standing four or five feet high near the 
edge of the path, with a groundwork of mauve and white single 
Asters, Ageratum, and the variegated sweet Alyssum ; or, if more 
colour is wanted, gold and orange Nemesia will be found to 
blend wonderfully with these mauve and white flowers.
