rcumstance; as such, it is very generally cultivated;
the flowers exhibit a pretty, innocent appearance, and strongly diffuse
an agreeable honey-like smell. They continue to blow through most of the
summer months.

It is a very proper plant for a wall or piece of rock-work; care must be
taken, however, not to sow too much of the seed in one pot, as it
spreads wide, but it may easily be reduced at any period of its growth,
as it does not creep at the root.

The specific description in the _Hortus Kewensis_ above referred to,
admirably characterizes the plant, but surely at the expence of its
generic character.

Grows wild among the corn in the South of Europe, is an annual, and,
like the _Sweet Alyssum_, generally cultivated in our gardens, and most
deservedly so indeed, for when a large assemblage of its blossoms are
expanded by the rays of the sun, their brilliancy is such as almost to
dazzle the eyes of the beholder.

Those annuals which bear our winter's frosts without injury, are
advantageously sown in the autumn; for by that means they flower more
early, and their seeds ripen with more certainty; the present plant is
one of those: it usually sows itself, and is therefore raised without
any trouble.

It begins to flower in May and June, and continues to enliven the garden
till August or September.
