very pretty. But the double forms--even the common variety,
_flore-pleno_--are to be preferred, being especially useful in semi-wild
spots. The type is wild in England, and frequently to be seen in hedges
and thickets.

R. CAROLINA.--For certain positions this is a useful Rose. It has erect
stems and forms dense thickets, spreading rapidly by means of the
numerous underground rhizomes it sends out in all directions. The
flowers are purplish-rose. A later-flowering variety known as
_nuttalliana_ is a stronger grower and has larger flowers. This will
flower up to September. _R. lucida_ and _R. nitida_ are, like _R.
carolina_, natives of North America, and are of similar habit, but they
are dwarfer and the leaves are more glossy. All these are apt to become
crowded with old stems, and, besides an occasional thinning out, are
much improved by dividing up every three or four years.

R. FERRUGINEA (R. RUBRIFOLIA).--This species, which comes from the
Pyrenees and Alps, is remarkable for the reddish-purple colour of its
leaves and young shoots. Groups of half-a-dozen or more plants give a
striking colour effect. The flowers are similar to the Dog Rose, but
red.

R. LAEVIGATA (R. SINICA).--Except in the south and south-west or in
similarly favoured localities, this is not really hardy, but where it
thrives it is a singularly beautiful Rose, perhaps unsurpassed among
single Roses in the size of its pure white flowers. It is known as the
Cherokee Rose, and is naturalised in some of the Southern United States.
A lovely hybrid between it and _R. indica_ has been raised and named
Anemone. Its flowers are soft rose.

R. LUTEA (Austrian Briar)--Of all the Wild Yellow Roses this is the most
beautiful. The yellow-flowered species do not, as a rule, thrive so well
as the others in gardens--one has only to mention such species as
_berberifolia_, _sulphurea_, _xanthina_ (or _Ecae_) to recall that. But
_R. lutea_, in strong loam with plenty of lime added, generally thrives
well. The copper-coloured varieties are more difficult to deal with in
suburban districts. The flowers of the typical _R. lutea_ are of the
brightest rich yellow. When in good health it produces each year long
arching shoots, wreathed from end to end with blossom. This species
comes from the Orient.

R. MICROPHYLLA--This interesting species is closely allied to _R.
rugosa_, and is a native of China. It has a sturdy bushy habit, few
spines, and the curious habit of pe
