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".
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?, NEED I GO ON? 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.....
i consider this a wonderful and ingenious method of evolutionary trends.
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 DOES NOT ABHOR!

<div dir="ltr">Hello guys,<br>
<div>I was just thinking if reproduction by seed ensures
genetic diversity and variation in plants, and if
cuttings produce an exact clone of the parent plant,
then why do variegated and  striated Sansevierias
