Or. Iridacece. A genus of very handsome plants
w h e n in flower. Sweet recommends them to be
e r o w n in a mixture of sandy loam and decayed
leaves, or peat soil. When they have done flowering,
they require no water till they begin to grow
a f r e s h . In October, they should be fresh potted,
and set in a cool f rame, as they only require to be
p r o t e c t e d from frost till their pots are wel l filled
w i t h roots; then they may be set on the shelves of
t h e ffreenhouse, and watered regularly, and they
wil l flower well. The species of this genus, and
some other bulbous-rooted genera, succe^ed best in
a pit, covered with lights in very cold or wet
w e a t h e r . Most of the species wi l l g row well in a
s o u t h border, in the open air, planted trom live to
s i x inches deep, in a light sandy soil, near a wall,
and to be covered wi t h dry l i t ter in severe weat
h e r : they will then flower much stronger than it
g r o w n in pots, and they maybe increased byoiisets
f r om the bulbs, or by seeds.
