Scientific name: Echinopsis bridgesii forma mostruosa
(From Clone B long 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 variegata.
NOTE: 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
monstrous growth (Clones A
clones B), Of the monstrous 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 monstrous and cristate growth whilst the second shows both
monstrous and variegated growth.
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 balanced fertilizer
Sun Exposure: This cactus need strong light exposures but it is subject to sun
burning during the hottest month of summer especially if the
temperatures are high and ventilation insufficient, 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.
can easily be multiplied from cutting. Single sections are taken off,
dried and rooted.
The chemical composition of the 'Penis Plant' is
supposedly the same as that of the typical
