One of the most ornamental hardy shrubs we possess; at once pleasing to
the eye, and grateful to the smell; for, as MILLER observes,
the whole plant in warm weather exudes a sweet glutinous substance,
which has a very strong balsamic scent, so as to perfume the
circumambient air to a great distance.

Its blossoms, which appear in June and July in great profusion, exhibit
a remarkable instance of quickly-fading beauty, opening and expanding to
the morning sun, and before night strewing the ground with their elegant
remains: as each succeeding day produces new blossoms, this deciduous
disposition of the petals, common to the genus, is the less to be
regretted.

Is a native of Spain and Portugal, prefers a dry soil and warm sheltered
situation, and in very severe seasons requires some kind of covering.

Cultivated 1656, by Mr. JOHN TRADESCANT, jun. _Ait. Hort. Kew._

Is readily increased from cuttings; but MILLER remarks, that
the best plants are raised from seeds.

Varies with waved leaves, and in having petals without a spot at the
base.

Is not the plant from whence the Ladanum of the shops is produced,
though affording in warmer countries than ours a similar gum, hence its
name of _ladanifera_ is not strictly proper.
