s, viz. about the end
of May and beginning of June, and continuing in blossom three weeks or a
month.

It is readily propagated by parting its roots in the autumn, may be kept
in pots, or planted in the open border, prefers a moist stiffish soil;
if carefully watered in dry weather, will grow among rock-work, for
which, from its size, it is well adapted.

The drawing here exhibited gives but a faint idea of the elegant and
lively appearance which this plant assumes when it grows in a tuft, and
a number of its branches are in blossom at the same time.

It is a hardy annual, of small stature, a native of Spain, and flowers
during most of the summer.

Was introduced into this country, according to Mr. AITON, in 1772, by
Mons. RICHARD, and deserves to be much more generally cultivated.

Some regard it as a biennial, but as seeds of it sown in the spring
flower the ensuing summer, and as the plant dies when it has ripened its
seeds, there appears more propriety in considering it as an annual.

It is to be sown in the same manner as other hardy annuals; will flower
earlier if the seeds have been raised in autumn.

The upper part of the stalk, as well as the leaves of the calyx, are
beset with viscous hairs, in which respect it does not perfectly accord
with LINNAEUS's description. _Vid. Sp. Pl. ed. 3. p. 854._
