The Trichocereus bridgesii mostruosa inermis( clone A short type )
is often known by the name "Penis Plant", it is much slower growing than
the standard form of the species.
Description: This is the clone A (The short
jointed one), one of the two Montrose form o
T.bridgesii It is a clustering monstrous cactus with prostrate
growth habit that branches at the base and can slowly grow up to 25 (-40)
Stem: Composed by short upright sections that branches avidly up
to 10-15 (-20) cm tall by 5 cm in diameter, light glaucous green, with
only a few areoles and spines in the basal portion. The upper part of
the stem is cylindrical, smooth without areoles and resemble a penis.
The lower part is spiny and shows a tendency to form ribs.
Spines: Honey-coloured to brown, located on the few basal nodes
in groups of up to 4. They can grow up to 4–7 cm long.
Flowers: Not known.
NOTE 1: There exist several mutant varieties of this
T.bridgesii that are highly prized by cactus impassioned. These
include a cristate variety, a variegated variety and two variants of monstrose growth (Clones A
clones B), Of the monstrose varieties, one (Clone B) is often known by the
name Penis Plant.
Two more recently developed clones are now available, the fist of which
exhibits both monstrose and cristate growth whilst the second shows both
monstrose and variegated growth.
NOTE 2: The chemical composition of the 'Penis Plant' is supposedly the same as
that of the typical
A particularity of this plant is that the buds emerge
through the plant's skin above an areole, rather than arising from
areoles or axils between areoles as in other cacti.
Scientific name: Echinopsis bridgesii forma mostruosa
inermis (Clone A short joined type)
Garden origin (Nursery
Conservation status: Listed in
CITES appendix 2.
Common Name: Some
people call this plant the "Penis plant" or "San Pedro penis",
it is also sometimes described as "The Pornographic Cactus’ or
the "The More Sensual of Cacti".
The German name for this cultivar "Frauenglück" is more poetic
than its English equivalent; it translates as "Women's Pleasure".
Synonyms: Echinopsis lageniformis forma mostruosa inermis
Cultivation: It is very easy to grow and cold hardy as low as -12°C
(or less). Need a fertile, well drained soil mix. Water the plants well
and allow them to dry before watering again. This cultivar seems to do
better with a little more water than most cacti. In fact, its
cultivation requirements are really more like 'normal' plants than most
other cacti. During the growing season fertilize them monthly with a
Sun Exposure: Outside
full sun, but during hot summers, the cactus are subject to sun
burning, so grow them in light shade, inside needs bright light, and
some direct sun.. During winter month, put them in a cool luminous place
and encourage them to enter winter dormancy by withholding water and
fertiliser over the winter as they will etiolate, or become thin, due to
lower levels of light. They are susceptible to fungal diseases if
overwatered, but are not nearly as sensitive as many other cacti,
especially in warm weather. They tend characteristically towards black
rotted spots unless watering is moderate and only in hot weather, if
kept damp through cold periods, they will invariably suffer.
Propagation: It can easily be multiplied from cutting. Single
sections are taken off, dried and rooted.
