Sempervivum 'Oddity' is a strange low-growing succulent with green,
tubular leaves tipped in burgundy.
Oddity is an evergreen rosette succulent with a mat forming growth
habit with densely clustered leaves. Differently to the leaves of most
sempervivums (That are broad and pointed) the ones of 'oddity' are
folded lengthwise and backwards so that they look like green cigarette
papers. Also very reminiscent of
Crassula ovata cv. 'Gollum' (syn. Crassula ovata cv.
'Hobbit'). 'Oddity' is relatively rapid growing cultivar that forms
little clumps that continues to spread. This cultivar occasionally has a
tendency to mutate with completely flat leaves.
Rosettes: Each rosette can be quite large and may have up to 50-60
pointed, with bristly margins, lime green tipped with crimson and
characteristically curl up to form tight rolls .
Star-shaped, held in flat cymes on the terminal ends of hairy, upright
Blooming season: Around June through August. The rosettes can
take several yeas to bloom and once they bloomed
dies after setting seeds,
but are replaced by new rosettes on lateral runners.
Sempervivum tectorum cv. ODDITY
Garden origin (It
was developed by American succulent enthusiast Sandy McPherson and it
was introduced to gardeners in 1977, and won the 1978 Bronze Rosette
Award for best new variety.
Common Names include: Cobweb Houseleek, Hens & Chicks.
It has occasionally been called "Trumpeter" as though each pipe was a
Curiosity: In Europe, the plants are sometimes used in roofing, with
the plants grown in between roofing tiles; they are believed to ward off
succulents are are from Europe and are very cold hardy and easy to grow.
Frost Tolerance: Hardy at least to -12°C (or
less). It makes a
wonderful ground cover. Good in rock, alpine or desert scape gardens
they are also used in concrete planters on either side of the front
entry. Great in window boxes or niches. Grows and spreads in poor soil
with little water & could rot if watered too
often. It enjoy full sun
, though in warmer climates it needs
protection from too much sun because it is not very heat tolerant.
However it is quite
adaptable and the little clumps can spread slowly also with a bit more
dampness and shade, so it not suffer in that location after all.
During the growing season, the plants are watered and
allowed to dry slightly before watering again. Although they can take a
great deal of drought, they seem to do better with regular (but
moderated) watering. During the winter months, plants are watered very
little. Outdoors it does not prefer rich loamy soil; gritty dirt with
pea gravel suits it. Excess moisture can damage the plant in winter and
it will benefit from being brought into the shelter of the greenhouse or
Propagation: Is very easily
propagated by division of larger clumps or by offsets, just
break off a piece and transplant.
