Graptopetalum is a small genus of 12 species from Mexico
and southwestern USA. They are similar looking to
Echeveria, although they are generally considered closer
to Sedum.
They are attractive rosette plants with thick subtly
colored leaves, occasionally speckled. Graptopetalum
leaves range in colour from waxy green to lovely pink and
grey-green. These plants are fairly delicate. They are
tricky primarily in their sensitivity to over-watering,
even what seems like insignificant over-watering can be
fatal. They are also sensitive to being handled, as skin
oil can damage leaves, in particular those with a
pearlescent colouration.
These plants produce five-petal flowers which range in
colour from white to hot pink and can be speckled, and
which grow on long inflorescences. They are long lasting
and produced in profusion in summer and fall. They are
followed by tiny seed pods.
Hardiness zone 9-11, (-5°C/25°F, 4°C/40°F). They will
take a light frost but are sensitive to excess heat.
Extended time in temperatures below freezing will kill
the plant, and temperatures which may go below 40°F
during extended period should be avoided. In winter, the
plants will require less water, as reduced temperature
and humidity will induce dormancy.
As with most Crassulaceae, Graptopetalum can tolerate
poor soil conditions, so long as it is well draining. Use
a commercial cactus and succulent soil mixture or 2 parts
common houseplant soil mixed with one part sand. Although
bright light is a requirement, heat is not. When grown in
a hot environment, these plants should not be placed in
full sun, or the plant will scorch and die. Allow the
soil to completely dry out before watering, and be
careful to avoid getting water on the leaves, this is of
utmost importance.
