they
carry this woolly substance with them, which being thus extended,
assumes the appearance of a cobweb, whence the name of the plant.

Like most of the Houseleeks it is best kept in a pot, or it will grow
well and appear to great advantage on a wall or piece of rock-work; the
more it is exposed to the sun, the more colour will enliven its stalks
and foliage, and the more brilliant will be its flowers; the latter make
their appearance in July.

It is propagated by offsets which it sends forth in abundance.

It is no uncommon practice to treat this beautiful species of Houseleek,
as a native of a warm climate; under such an idea we have seen it nursed
up in stoves, while the plant spontaneously braves the cold of the
Switzerland Alps.

If there be any one genus of plants more universally admired than the
others, it is that of the Rose--where is the Poet that has not
celebrated it? where the Painter that has not made it an object of his
imitative art?

In the opinion of MILLER, the Moss Rose, or Moss Province, as
it is frequently called, is a perfectly distinct species;
LINNAEUS considers it as a variety only of the _centifolia_: as
it is found in our Nurseries in a double state only, and as we are
ignorant of what country it is the produce, the decision of this matter
must be left to future observation and inquiry.

Though it may not increase so fast by suckers, nor be increased so
readily by layers, as the _centifolia_, there is no difficulty in
propagating it either way; the latter mode is usually adopted.
