a family that is almost completely succulent? ‘others’.
Fig. 1
Tylecodon buchholzianus
Some other succulents continued 19
Tylecodon buchholzianus
Let us start with a typical plant that grows in winter.
The picture shown on the previous page is a little
atypical. In typical habitats, Tylecodon species first
produce the flowers and then the leaves. If the
plants are well fed however, and the growing
conditions are good, they do not necessarily shed
their leaves.
The shedding of the leaves during the rest period is
exactly the characteristic that was used in the
separation of this genus from Cotyledon, in which
all species were previously included. Therefore, the
generic name is only an anagram of Cotyledon:
Tylecodon.
In habitat, with the pronounced dry seasons, the
species shed their leaves and then stand ‘naked’
for a long time. Many small species can then hardly
be found above ground. Our species here is a
mediator between the tiny and the larger, (up to 2m
high trees), which are united in this genus today.
The plant shown is no more than 20cm and will
only grow slightly taller (Fig. 1).
Contrary to the widespread opinion in the literature
that this species blooms poorly, my plants are in full
bloom in the autumn. It is not uncommon for me to
have 50 or more flowers on the stems. The
numerous flowers in every condition can be clearly Fig. 2
seen in the picture. After the abundant flowering,
the leaves come – which, as described above, can Anacampseros lanceolata

Anacampseros lanigera SB1179
it is not bad if you do not give the species any
water during the summer, then the leaves will be Fig. 3
shed safely. I water a little bit all year round –
simply because I do not feel like treating it very
differently from the other plants. Let us put it this
way: I try to give less water in summer! Watering is
intensified when new life, that is, buds, appear on
the plant. Then I water regularly but very sparingly
in cold periods. My plants stand in a very bright
position in winter, right behind the glass, at a
minimum of 10°C. So, the species grows safely,
albeit slowly.
Anacampseros
The meaning of the generic name is not entirely
certain. The most likely – and most beautiful –
explanation is that it derives from the Greek words
‘anakamptein’ for ‘bring back’ and ‘eros’ for ‘love’,
as ‘bringing back the love’. Plinius used it to
designate a plant that was said to have an
aphrodisiac effect in antiquity, but which is now
counted as Hylotelephium.
According to the latest research, the genus no
longer belongs to the Portulacaceae family, but to
the newly described Anacampserotaceae family.
Depending on the opinion, one to four generic
names are used today to subdivide the almost 60
taxa. Plants from South America, southern and
eastern Africa and Australia are then included.

I would like to share with you a picture which first came to

my attention in the mid 1970s, not long after I had been
introduced to cacti and other succulents.
Carl Spitzweg
by Tony Clifford
‘The Cactus Friend’ (Der Kaktusfreund), painted around 1856 and depicted on a
postcard. Spitzweg often painted alternative versions of his pictures, and there is at
least one other version of this one.
Carl Spitzweg continued 34
The artist is Carl Spitzweg (1808-1885), a

German painter who liked painting
eccentrics, collectors and many who would
today be called obsessives.
These include, for instance, the wonderful
‘Bookworm’ (1850), ‘Hypochondriac’
(c1865) and ‘Mineral Collector in the
Grotto’ (c1880).
But I want to talk about ‘The Cactus
Friend’ (Der Kaktusfreund), painted around
1856 and currently located in the Museum
Georg Schafer in Scheinfurt, Bavaria, which
has a comprehensive collection of 160
paintings and 110 drawings by Spitzweg.
I have a Swiss postcard (see previous

page), posted in 1930, which reproduces
‘The Cactus Friend’. The sender has
written underneath the picture “Daddy
when he retired”, which probably sums it
up very well.
An elderly gent is standing in his yard,

surrounded by pots of cacti. He is looking
studiously at what is certainly a flowering
Mammillaria. Other plants shown include
Opuntia, Agave, Aloe and Echinopsis. A
watering can is evidence that the gent is
looking after his collection.
Spitzweg trained in pharmacy at the

University of Vienna, and was a pharmacist
and newspaper illustrator before becoming
a painter in 1833. It is amazing to discover
that he had no formal art training and is
generally well thought of: “He was
provincial in his choice of subjects;
tenderly, humorously, but with firm control
of light, shadow, composition, and detail,
he portrayed small town misfits, street
musicians, postmen, night watchmen, and
lovers bidding farewell”. He is widely
recognised as the most representative of
the Biedermeier (early Victorian) artists in
Germany.
Spitzweg produced another charming oil

on canvas, called ‘The Cactus Lover’ (Der
Kaktusliebhauber) (c1860) in which a gent
surrounded by bundles of papers is staring
at what is certainly a tall, lopsided
Mammillaria. There are other small cacti on
the windowsill.
Perhaps this is the same gent before

retiring? There is no sign of a greenhouse

I thought this time I would choose just one

series of Mammillaria to recall some of my
successes and failures in growing these
plants. The series Ancistracanthae in the
section Hydrochylus (= watery sap)
consists of about 24 species, some of
which I am sure will be very familiar to you
while others are less common, so I will just
describe and illustrate some of my
favourites. I consider quite a few of the
species in this series to be tricky to grow
and/or short-lived so, if you like a
challenge, they would be a good place
to start.

The succulents of Portmeirion pottery continued 48
Introduction
My interest in the Botanic Garden range of
Portmeirion pottery was initially stimulated
in 2002 by my New Zealand friends
Frances and Ted Verrity. They were avid
collectors of the design and they started
my own modest collection through a gift of
a small Portmeirion plate which features an
Aloe. I have since added a medium sized
plate featuring Cactus grandiflorus. Ted
documented the story of their Portmeirion
collecting activities and their two plates
with succulent motifs in the ‘New Zealand
Cactus & Succulent Journal’ (Verrity, 2003).
Last year I was thrilled to inherit a large
Portmeirion bowl embellished with many
plant motifs including the Aloe featured on
the small plate. This article tells the story
of this pottery, focussing especially on the
history of the two succulents that form
part of the much wider range of Botanic
Garden motifs.
Portmeirion Botanic Garden Pottery
In 1925 the architect Sir Clough Williams-
Ellis began the creation of the romantic
Italianate Portmeirion village in North
Wales. His daughter, Susan Williams-Ellis,
inherited his love of design and began a
career in pottery in the 1950s with her
designs intended primarily for the
Portmeirion village shop. The business Fig. 2
grew and in 1960/1 she and her husband,
Euan Cooper-Willis, bought two factories succulents feature in the range and these Aloe vera from
in Stoke-on-Trent where pottery with are the focus here. Jenkins & McKay (2000) Green (1824)

However, it was not until 1972 that the is at Fig. 1. This is highly stylised and the

hand-coloured illustration. However, it

seems likely that Green similarly copied
this image from an earlier source, since
most if not all of the plant images in
Green’s herbal have been copied from
earlier works, usually uncredited. A most
likely source is from an 18th century book
by John Hill, who was a prolific but
notorious author on many subjects, not
just botany and horticulture. Many of his
botanical books and herbals feature
succulents. I have three of these books
but this particular aloe engraving is not
amongst them. It is possible that Aloe
barbadensis is included in one of the rare
Hill books which I have yet to track down
and examine.
Fig. 3 shows the backing to the aloe plate,
which appears to be a standard-sized
‘bread and butter’ plate (Jenkins & McKay,
2000). The aloe motif was introduced in
1972 and retired in 1976.

which features seven Botanic Garden
motifs with Passiflora caerulea as the
centre piece, the aloe being amongst six Fig. 3
motifs on the bowl’s outer surface.

The final general note on the Botanic
Garden motifs is that most but not all of
the plant images I have examined are
accompanied by insects, usually but not
exclusively, butterflies and moths. I know
nothing about the origins of these insect
images and Jenkins & McKay (2000) have Portmeirion Botanic Garden bowl featuring

catalogue all the pottery items in the introduced in 1973 and retired in 1985.
Jenkins & McKay (2000) give the origin of

this cactus motif as Green (1824) but this is
only part of the story. No doubt the
Portmeirion designers would have had
access to a copy of Green’s herbal and
would have freely copied images from this.
However, as mentioned above, Green
himself copied most if not all of his images
from earlier 18th century books.
It transpires, therefore, that the Portmeirion
cactus motif originates from a very famous
18th century book authored by Philip Miller,
who was superintendent at the Chelsea
Physic Garden from 1722 till 1770 (Le
Rougetel, 1990). Miller’s botanical and
horticultural publications began in 1724
with the small-scale and small-sized ‘The
gardeners and florists dictionary, or a
complete system of horticulture’.
This was principally a compilation of
extracts from the writings of others, Fig. 6

relatively modest scale. Incidentally
