Mark, you're talking above your pay grade here, aren't you? We're talking a=
bout sansevierias, not begonias, trilliums and aroids. What is your referen=
ce that variegated mutations might be an evolutionary trend that allows the=
plant to lose the ability to produce chlorophyll to throw a predator into =
confusion, or the anthropomorphic view that the variegated plant cares abou=
t the beauty humans might see if it loses the ability to produce chlorophyl=
l? Indeed, we often see the mericinal variegated sansevieria revert back to=
an all green leaf - its natural condition - as if it was saying, "Oops, th=
is was a mistake!". I agree that variegated plants are beautiful, I prefer =
them. But it might well be that cultivation by admiring humans is the prima=
ry reason that variegated sansevierias continue to be found in so many coll=
ections. Your turn.
Ben, you are absolutely correct that variegated sansevierias are open to su=
nburn....the more variegation the more susceptible. They are also more sens=
itive to cold, and bruising which leave ugly brown spots. Yet, highly varie=
gated plants need the suns light even more because the available chlorophyl=
l is feeding the entire plant/leaf. Its a bit of a balancing act. By all me=
ans get your sansevierias outside if you can. I have good luck with open sh=
ade for my variegated plants. Fresh air is also beneficial. Please post a p=
icture of trifasciata 'Pulsar'; I don't know this variety.

While the 1st four sentences are of-course absolutely correct, I have to po=
int 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 M=
ANY aroids (such as Aglaeonema, Dieffenbachia, Monstera, Rhapidophora, Cala=
dium. Scindapsus, Zantedeschia)....the list goes on and on, ...entire popul=
ations of native variegated Gusmania's here in the Fakahatchee of the Everg=
lades, as-well-as Calatheas, the related Marantas, and endless supply of wi=
ld 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 bl=
essed with an extra touch of supremacy and beauty apparently reserved for a=
distinct but vast array of natural, wild, plant-life, (as-well-as cultivar=
s) that nature DOES NOT ABHOR!

Subject: [Sansevierias] Sansevieria propagation Question
Hello guys,
I was just thinking if reproduction by seed ensures genetic diversity and v=
ariation in plants, and if cuttings produce an exact clone of the parent pl=
ant, then why do variegated and striated Sansevierias reproduce non-varieg=
ated and non-striated plants when propagated by a leaf cutting?
