P. UNDULATUM, from Australia (1789), is also hardy against a wall, but
cannot be depended upon generally. It is a neat shrub, with wavy leaves,
that are rendered conspicuous by the dark midribs. They grow well in any
good garden soil.
PLAGIANTHUS.
PLAGIANTHUS LYALLI, a native of New Zealand (1871), and a member of the
Mallow family, is a free-flowering and beautiful shrub, but one that
cannot be recommended for general planting in this country. At Kew it
does well and flowers freely on an east wall. The flowers are
snow-white, with golden-yellow anthers, and produced on the ends of the
last season's branchlets during June and July. The flower-stalks, being
fully 2 inches long, give to the flowers a very graceful appearance. In
this country the leaves are frequently retained till spring.
P. LAMPENI.--Van Dieman's Land, 1833. This is about equally hardy with
the former, and produces a great abundance of sweetly-scented flowers.
P. PULCHELLUS (_syn Sida pulchella_).--Australia and Tasmania. Another
half-hardy species, which bears, even in a young state, an abundance of
rather small, whitish flowers.
POLYGALA.
POLYGALA CHAMAEBUXUS.--Bastard Box. A neat little shrubby plant, with
small ovate, coriaceous leaves, and fragrant yellow and cream flowers.
P. chamaebuxus purpureus differs in bearing rich reddish-purple flowers,
and is one of the most showy and beautiful of rock plants.
