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.

The Tangier Pea, a native of Morocco, cannot boast the agreeable scent,
or variety of colours of the sweet Pea; nor does it continue so long in
flower; nevertheless there is a richness in the colour of its blossoms,
which entitles it to a place in the gardens of the curious, in which it
is usually sown in the spring, with other hardy annuals.

It flowers in June and July.

The best mode of propagating it, is to, sow the seeds on the borders in
patches, where the plants are to remain; thinning them when they come
up, so as to leave only two or three together.

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 ci
