Great examples, and great group discussion. Looks like in those cases, lack
of pigment is not selected against and those plants have found their
niches. I think all of these examples might still be the exceptions and not
the rule.
I know with animals, lack of pigment is definitely a weakness and
abomination in nature. But in captivity, animals with less pigment are
regarded as little treasures.
Personally, I've had a tough time keeping variegated sansevierias like S.
guineensis and S. trifasciata pulsar alive. I was growing them in a dimly
lit area indoors, under a daylight lamp. The soil had lots of perlite and
wood chimp and I wasn't keeping the soil too moist. They would live for
several months and then rot.
Do you think keeping them outdoors under shade would solve this problem? On
one hand, I think variegation would get sunburn outdoors, but on the other
hand, I think the sun would help the few existing chloroplasts to make food
for the entire plant for growth. So why should I do? Would partial sun be
best? Thanks

While the 1st four sentences are of-course absolutely correct, I
have to point out that the last statement is sorrowfully incorrect:
"Nature considers variegation an abomination, a weakness, and it
tries to weed out weakness".<br>
<br>
It needs to be pointed-out that there are many species of Passiflora
which are are ALWAYS variegated IN THEIR WILD NATIVE HABITATS, as
well as many MANY aroids (such as Aglaeonema, Dieffenbachia,
Monstera, Rhapidophora, Caladium. Scindapsus, Zantedeschia)....the
list goes on and on, ...entire populations of native variegated
Gusmania's here in the Fakahatchee of the Everglades, as-well-as
Calatheas, the related Marantas, and endless supply of wild gingers,
Trilliums, Hepatica's, and do i even need to mention Begonia's,=
also
many orchids, Sarracenia's etc?,=C2=A0 NEED I GO ON?=C2=A0 In many =
cases, this
is, in evolutionary terms, perhaps a method of confusing would-be
predators who might not recognize a distinctly variegated plant as
what would be it's normal host.....<br>
<br>
i consider this a wonderful and ingenious method of evolutionary
trends.<br>
<br>
I believe that quite to the contrary, variegated species are
especially blessed with an extra touch of supremacy and beauty
apparently reserved for a distinct but vast array of natural, wild,
plant-life, (as-well-as cultivars) that nature=C2=A0 DOES NOT ABHOR!<br=

If a variegated sansevieria leaf is severed to make leaf
cuttings for propagation purposes, it can only produce two
types of plants: either all green or all albino depending
on WHERE the new plantlet originates on the leaf-cut
surface. The young albino plant cannot survive if it is
detached from the cutting, while the green plantlet will
be fine. Nature considers variegation an abomination, a
weakness, and it tries to weed out weakness.</div>
