Columnar Cacti
Buck Hemenway
For the purpose of our Mini-Show, these
will be all cacti that tend to grow as upright stems,
whether they are solitary (one stem) or multiple
stems ramifying from the base of the plant or
single or multiple stems branching higher up.
Any plant genus that ends in the word cereus (aka
“ceriod”), such as Oreocereus, Pachycereus,
Trichocereus etc, is part of this group. We will
include all of the upright growing Echinopsis (for
the most part the old Trichocereus), Cleistocactus.
Basically any cactus that tends to grow relatively
tall and relatively skinny.
The plant that we are most familiar with is
the Saguaro (Carnegia gigantea) which is the largest
growing of the columnars in the United States.
The Cardon (Pachycereus pringlei) grows
prolifically in Northwestern Mexico and on the
Baja Peninsula. Both of these plants are very easy
to grow in our Inland climate as long as they are
planted in very well draining soil. They both grow
in the Sonoran desert and as such need some
added summer water here, but can be left alone
the rest of the year. They and most of the very
large “ceriods” can do well with one good
watering per month from July through October
when they are good sized.
The group tends to be pest free. Just a little
inspection once or twice a year will show any
evidence of scale or mealy bug.
They tend to have very large, and shallow
root systems. We always water the areas in which
they grow with overhead sprinkling so they can
gain as much root growth as possible.
Transplanting of nearly all columnar cacti
should be done in the heat of the year (from May
through September). We do not water the large
ones at all during the first summer/winter after
planting. They have plenty of reserve energy to
begin new root growth before our rainy season.
Many of them grow at extreme altitudes in
the Andes and their connected mountain ranges.
Our weather tends to be a little too hot, but most
adapt well after a season or two.
The blooms are huge and trumpet shaped
on many. The fruits on all are edible and normally
delicious. Wait until they begin to turn red or
purple in the case of Myrtillocactus.
The most satisfying plants in our landscape
are the large columnar cacti.

Haworthia,Gasteria
By: Buck Hemenway
As we have learned from our study of
Aloe, the genera Haworthia and Gasteria are
closely related and included in the same large
family Xanthorrhoeacae.
These genera grow exclusively in Africa
and mainly in South Africa. They grow in the
Karoos of South Africa as well as some of the areas
with greater rainfall in the south and east of the
country.
There is a lot of discussion about the
relationship of species in Haworthia. We should
exoect a reorganization of the genus in the next 10
years or so.
The Gasteria genus is due a reorganization.
Ernst van Jaarsveld is working on a book that
should be published soon.
Haworthia plants tend to be smallish
rosettes up to about 12” in diameter for the largest.
Gasteria are generally larger plants than
Haworthia many of which do not form rosettes,
but the leaves stay in ranks which is known as
“distichous” growth botanically.
Most of the plants in this group are
opportunistic growers. This means that under
mild conditions they will grow any time of the
year. We find blooms on them year around based
on individual species. They do not like very cold
or very hot weather. Withholding water in the
coldest and hottest times of the year will help the
growth of these beautiful plants.
Flowers on Haworthias are not useful in
describing species. They resemble each other
closely. We use the growth habit of the plants for
classicification almost exclusively.
Flowers on Gasterias are more varied and
quite showy. The shape of the flowers is how the
genus got its name. They all look like little
stomachs.
Both genera are very suceptible to our
common pests, particulrarly mealy bugs.
Common in Gasterias is a black spot fungus. This
is a pest that can infect an entire collection in short
time if not controlled. One should use a broad
based fungicide to kill the fungus. The black spots
will not disapear, but the fugus will not spread
further.
