Grows spontaneously in dry situations, in the southernmost parts of
Europe, where it is shrubby; and in similar situations it is so in some
degree with us; but on our flower-borders, where it is usually sown, it
grows so luxuriantly, that the stalks becoming juicy and tender, are
generally destroyed by our frosts; hence it is an annual from
peculiarity of circumstance; 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.
