This is a very popular cultivar with only 3 ribs covered with
white flecks.
|
Description: It is a
strikingly pretty, old
cultivar with
only three ribs with light or dense
white flecks
that cover the
stem. Nude
plants (see)
are also known and very appreciated. This cultivar tends to be unstable,
and some of the three ribbed specimens develop additional ribs as they
age. Old and big plants which maintain the typical three ribbed shape
are very very prized.
Flowers: arise from the areole at the tip of the stem on
mature plant (at least 4-5 years old) they are large, funnel-shaped,
yellow, 5-7 cm wide. Blooming
intermittently throughout the warm months from spring to autumn.

Cultivation:
Although regarded as a choice and difficult plant in cultivation it is
relatively easy to grow.
It is frequently seen as a grafted plant, but grows very
well on its own roots, too. Use mineral well-permeable
substratum
with little organic matter (peat, humus). Water
sparingly from
March till October and keep perfectly dry in
winter
at temperatures from 5 to 15 degrees centigrade.
(but it is
hardy to -7°C for short periods) In
the rest period no high atmospheric humidity!!
Sun Exposure:
Light shade to full sun. This cultivar tends to be slower growing.
