The best situation for most plants while in flower, is where they are
shaded from the sun, and fully exposed to the air. _Primroses_, both
European and Chinese, flower best, and the colours are finest when the
plants are in the front of the house, and entirely shaded from the sun.
The Chinese _Azàleas_ and _Rhododéndrons_ require, while in flower, a
similar situation. Have all the shoots tied naturally to neat rods, and
keep them clear from others by elevating them on empty pots, or any
other substitute. See that there are no insect upon them; for they make
a miserable contrast with flowers. The _Cálla æthiopica_ should stand in
water when in flower, and even before flowering they will be much
strengthened by it.
