_Tigrídia_, a genus of Mexican bulbs belonging to _Monadelphia
Triándria_, and produce the most beautiful flowers of the natural order
of _Irideæ_. _T. pavònia_ is of the brightest scarlet, tinged and
spotted with pure yellow. _T. conchiiflòra_, colour rich yellow, tinged
and spotted with bright crimson. The colours are very rich, and purely
contrasted. The corolla is about four inches in diameter, composed of
six petals; the outer are reflexed, the flower of the largest, though
splendid in beauty, exists only one day; but to compensate for that, a
plant will produce flowers for several weeks; and where a bed of them
can be collected, they will bloom in profusion from July to September.
They like a light rich free soil. Lift the bulbs in October, and
preserve them as directed in that month for _Tuberoses_. Be sure that
they be kept dry, and secure from frost. A bed of these should be in
every garden. A writer says, "it is the most beautiful flower that is
cultivated." Plant them about the end of this or first of next month; if
in beds keep them one foot apart each way.
