Variegation: A variegated plant has sectors, patches or stripes
with two or more different colours, even distinct shades of green.
Plants with variegated stems or leaves are often
In most species the
stems or leaves are normally green, and variegated epidermis is an
mutation, termed a
chimera. A chimeral variegation is due to losing the ability to
chlorophyll in some of the plantís
tissue, so that this tissue is no longer green. Tissues lacking
chlorophyll are usually white or pale yellow coloured (due to
pigments) or red (due to
anthocyanin pigments) contrasting with the normal green tissue.
There are several forms of variegation, depending on the tissues that
have been affected. The variegation in some forms is unstable. The
extent and nature of the variegation can vary, and sometimes the plant
will return to the green form. In others it is stable and does not
change under normal conditions. Because the variegation is due to the
presence of two kinds of plant tissue, propagating the plant must be by
vegetative method of
propagation that preserves both types of tissue in relation to each
echinofossulocacti are regarded as choice and difficult in cultivation,
relatively easy to care for, and flower. But be aware that
they cannot tolerate prolonged exposure to direct sunlight
(especially during the hottest summer days), so grow them in half-shade
or under filtered sun. They are sometime seen as grafted plants, but
many grow well on their own roots, too.
On the contrary,
albinos can survive only if grafted on a strong green base.
Use mineral well-permeable substratum with little organic matter (peat, humus). Water
March till October, and keep perfectly dry in
at temperatures from 5 to 15 degrees centigrade.
(In general these plants are more tender and cannot endure
freezing temperatures). In
the rest period no high atmospheric humidity!!
Propagation: Almost usually by seed. Plants are often
grafted onto column-shaped cacti.
