Sempervivum
arachnoideum var. tomentosum
Cobweb Buttons
One of the most distinctive types of
Sempervivum. Aptly named, 'Cobweb' is covered with fine,
white threads which crisscross between the leaves' tips
like a cobweb. Each rosette of pointy, blue-green leaves
grows about 1 inch wide. Their color may vary from
season to season. Unusual rose-red flowers are produced
on leafy stalks in midsummer.
Sempervivum is comprised
of one large rosette called the "hen" which sprouts many
smaller rosettes around it called "chicks". As the plants
age, the "hen" may die out and be replaced by the "chicks".
Plants can be divided easily at any time by pulling up some
of the "chicks" and replanting them elsewhere.
This plant is particularly
effective when planted in the cracks and crevices of stone
walls or walkways. It is also very attractive in containers

More Information
Sempervivum is the perfect plant for hot, dry,
sunny locations with very well-drained soil. Though they can
adapt to a variety of soil types, they perform best in gritty
soil. If a groundcover effect is desired, space plants close
together because they grow slowly.
Actually forms cobwebs that extend from leaf tips
over the top of the crown. Cobwebs may disappear in winter,
although abundant in the summer.
