"Salicornia,
The Sonoran Desert Succulent That
Could""

Jon will
open the
eyes of
succulent
lovers and
introduce a
plant that
manages to
withstand
almost
anything.
You must
attend to
get the real
picture.
Nearly
one
third
of
the
arable
land
on
earth
has
a
significant
salinity
problem.
Not
only
does
this
reduce
crop
yields
for
a
hungry
planet,
but
the
situation
is
most
critical
in
the
poorest
countries
which
often
experience
poor
harvests.
The
consequences
of
this
are
not
only
hunger
but
also
include
profound
social
and
political
consequences
as
hungry
people
migrate
to
other
regions.
From
1980
to
1992,
Jon
worked
on
the
Halophyte
Project
at
the
Environmental
Research
Laboratory
of
the
University
of
Arizona.
There
are
approximately
400,000
species
of
plants
in
the
world
of
which
about
10,000
are
believed
to
have
some
degree
of
salt
tolerance.
The
objective
of
this
research
was
to
investigate
as
many
as
possible
of
the
estimated
10,000
species
of
halophytes
which
occur
mostly
in
coastal
habitats
worldwide
to
determine
if
any
of
the
species
possessed
the
features
required
to
be a
successful
crop
plant
that
could
be
irrigated
with
low
quality
brackish
water
or
seawater.
After
reviewing
several
hundred
species
of
halophytes,
the
Lab
settled
on a
widespread
western
hemisphere
halophyte,
Salicornia
bigelovii.
This
species
occurs
intermittently
along
the
coastlines
of
the
United
States
and
Mexico
as
isolated
ecotypes.
These
ecotypes
have
features
which
make
them
attractive
candidates
for
a
halophytic
crop
as
well
as
numerous
features
which
are
barriers
to
becoming
a
crop
plant.
This
research
focused
on
condensing
the
required
characteristics
of a
crop
plant
into
a
bred
selection
while
simultaneously
breeding
out
the
characteristics
which
would
prevent
the
type
from
being
successful
as a
seawater
irrigated
crop.
The
research
also
included
developing
the
farming
techniques
for
a
species
which
had
never
before
been
farmed.
As
is
often
the
case
in
research,
Jon
started
out
with
some
ideas
that
appeared
to
make
sense
at
the
beginning
but
during
the
course
of
the
work
got
an
education
from
the
plants
which
he
claims
are
a
lot
smarter
than
he
will
ever
be.
The
research
also
included
traveling
extensively
throughout
Mexico
Jon
was born and
raised in
Stratford,
Connecticut.
He received
a B.A. from
Gettysburg
College in
1971 and in
1975 started
Landscape
Cacti, a
desert
nursery
devoted to
growing
cacti and
agaves from
seed fro
landscape
use. In 1986
he received
a Ph.D. from
the
University
of Arizona
and worked
as a
research
Scientist
for the
University
from 1986 to
1992 while
living along
the coast of
Sonora,
Mexico. Jon
collected
halophytes
and was
farming them
in Kino Bay
at Puerto Penasco,
Sonora.
Since 1992
to the
present Jon
has operated
Landscape
Cacti where
he grows
landscape
cacti and
agaves.
Be sure to
join us for
Jon's
experience
in growing
landscape
cacti and
his talk on
the
Salicornia.
