THE FLORIST’S JOURNAL, 
while the elegant form of Hottonia palustris , “ the naiad of the 
stream,” enlivens many a month with its rosy flowers peeping 
from among the sedge, and the dead leaves of grasses by which 
it is environed Menyanthes trifoliata again decks the margin 
of our English ditches with its interesting and lovely flowers, 
while the Richardia cethiopica , or Calla (Ethiopica , from the 
remarkable purity of its wax-like flowers, fixed on their long 
elastic stems, wave in graceful motion by the summer’s evening 
zephyr reflected in the mirrored surface of the water. 
The situation best adapted for hardy aquatics is found to be 
in accordance with the height attained by them ; and accord¬ 
ing to this feature, so must the depth of water be regulated in 
which they are to be immerged: thus the Richardici (Ethiopica , 
Nymphcea alba , and Nuphar lutea , require a depth of from one 
to two feet, while the Caltha palustris , Hydrocharis morsus- 
rance, Sagittaria sagittifolia , Acorus Calamus , Butomus umbel - 
latus , Zannichellia palustris , &c., should be planted from 6 to 
12 inches from the surface of the water; Hottonia palustris , 
Menyanthes trifoliata , and Aponogeton distachyon, should be 
potted, and the pot fixed so as to be half immersed in the 
water. After the blooming season of the Aponogeton is over, 
and the leaves look yellow, they may be taken up and dried, 
and again excited in the following March. Stratiotes aloides, 
which is one of the most curious indigenous aquatics, should 
also be kept with half the pot under water. 
As some arrangement is requisite for plants of this descrip¬ 
tion, it is desirable that ledges should be made in ponds or 
tanks where these plants are to be grown for them to be placed 
upon, according to their height, and also for the blending of 
their colours: the low growing varieties, being generally the 
more tender, should, for this reason, as well as to preserve a 
more systematic appearance, be placed at the margin, while 
those of larger growth and greater altitude should be planted 
towards the centre. The situation for Nymphcea alba and 
Nuphar lutea should be either in ponds or fast currents; the 
two, planted together at the edge of a waterfall, will blend 
their noble flowers in rich luxuriance amidst the surging foam 
of the surrounding water. Most of the other species prefer a 
shady situation, and are to be found in Nature’s untrodden 
wilds,
