Class Magnoliopsida (Dicotyledons)
Similar to jovibarba
, the taxonomy
is still widely disputed.
is an Asian
genus of monocarpic
, similar in appearance to jovibarba
, but it looks most similar to aeonium
. One of the major visible differences between aeonium
is that each leaf is tipped with a spine
. It is a fast-growing succulent
, with grey or green leaves forming small, globular rosettes
. The small bell
-shaped flowers are usually white or pink and grow densely packed on a conical inflorescense
(which are really quite amazing to see, up to 12 inches tall). Natively, the plant lives in Korea
, and Northern Japan
Some species show amazing symmetry
of the rosette
. Orostachys spinosa
is of note, as the leaf pattern follows a Fibonacci sequence
" (due to the conical flower stalk).
As with most similar genera
, this plant can survive in fairly poor soil, so long as it is well draining. This genera
is very cold-hardy and can survive temperatures to -30°(fahrenheit
). Allow soil to dry to the touch between waterings, and avoid getting water on the rosettes
requires some bright light
. This plant doesn't tolerate high humidity
grows actively in spring and summer.
self-propagates through offshoots, and given time one plant will form a dense mat of many. Propagation
is primarily through offset separation.
To separate an offset
, remove soil from the base of the offset to find the stolon
which attaches the pup to the mother plant
). It is best to use an offset which has already established some roots of its own. Cut the stolon
close to the pup (to discourage roots growing from the stolon
). Place the offset into a small pot with well-draining, sandy soil. Do not water until new growth is noted.
PRUNING AND GENERAL CARE:
In general, this is a good plant to forget about. Leave it in a bright sunny
location and water very sparingly. Water in the morning so as to prevent water from remaining on the leaves during the night. Remove any dead leaves from rosettes, as dead leaves invite rot
). When a rosette
has flowered, it will die
In the event of an unhealthy plant, the first thing to examine is your watering habits. The most common problem is root rot due to overwatering. If the soil
is too wet
, don't hope it will safely dry out so long as you don't water it for a while. Replace the soil immediately.
One of the most common pests to houseplants
is the mealybug, and your orostachys
may fall prey to this pest. However, due to the tightly packed leaves, more often than not the mealybugs
will attack the roots
. This makes them far less visible than mealybugs
which attack leaf-stem junctions. The symptoms of a root mealybug infestation is slowed or stopped growth (though in winter
this is a normal sign of dormancy
). If this occurs without apparent cause, remove the plant from the pot and examine the roots. A white cottony substance on the roots and in the soil is a sure sign of mealybug infestation. Remove all soil
and wash the roots gently. Remove any roots which appear damaged with a sharp sterile knife
. Let them dry very throroughly before replanting.
