Though not so beautiful as many of the genus, this species is a common
inhabitant of the flower-garden, in which it continues to blossom,
during most of the summer.

It is a native of Italy, and delights in a dry soil and situation; it
will even flourish on walls, and hence will serve very well to decorate
the more elevated parts of rock-work.

When once introduced it comes up spontaneously from seeds.
