Bizarre Plants Only a Mother Could Love
Reprinted from American Nurseryman Magazine 1997

Have you ever seen a plant so bizarre that you thought no one would ever buy it? Many
nurserymen have become so convinced that customers want nothing but taxus, thuja, and ilex,
that they miss out on some of the most fun plants that the Plant Kingdom has to offer. When we
hear from a poll that 68% of the gardening public wants to spend less time in their garden, we
assume that we should grow more boring plants and make them easier to maintain. Sorry, but I
beg to differ.
I feel we need to encourage people to have more fun in their gardens! Let's get real...how
many people want to spend time in their gardens if all they have to do is the hedge clipper shuffle
and the sprayer sprint. As nurserymen, we have done our best to promote and produce the most
boring plants that money could buy. No wonder folks don't want to spend more time in their
gardens...starring at a Japanese holly for an hour is not my idea of a leisure activity.
People are constantly surprised at the rise in popularity of perennials, but not those us who
are perennial nuts. Let's face it, perennials as a group are fun! With perennials, there is always
something changing, highlighted by anticipation. I'm certainly not going to tell you that all
perennials are fun, but let's look at a few really bizarre plants that are sure to make your
customers take notice.
There is probably no group of plants that evokes more emotion and curiosity as the
amorphophallus or voodoo lilies. This primarily Asian genus loosely translated indicates that the
flower resembles a sexual part of the human anatomy...you guess which one. You are likely to
remember the "stink" that was raised last summer when A. titanium flowered at Kew Gardens in
England. Every news magazine, newspaper, and news television show featured the grand event.
No plant has ever received such press...except maybe Cannabis sativae.
Amorphophallus konjac (syn. A. rivieri), hardy from zone 7b-10 is the most common
species in the trade, and is beginning to pop up even in "reputable" catalogs. The giant hand
shaped leaf to 3' across is held atop a mottled fleshy stem that arises from a giant tuber (5-10 lbs).
When the bulb gets large, it flowers a couple of months before the leaf emerges with a bizarre 6'
tall stalk of purple fleshy vinyl sitting atop a 3' wide vinyl cup. While the odor is the stuff great
stories are made of, the smell of rotting flesh is quite evident for at least one day during the bloom
cycle. Since the bulb will bloom without being potted, many of our customers play practical
jokes on their family by hiding a bulb in the house during the winter time and watching with
delight as family member try to locate a "dead animal".
A. bulbifer, zone 7b-10 is another wonderful species, but without the odor. The 2' tall
shell pink flower has a similar habit to A. konjac. A. titanium (hardiness unknown) is the most
spectacular of the genus with it's potentially 15' tall inflorescence. A. titanium is still quite rare in
the trade, although tissue culture breakthroughs are promising.
A first cousin to amorphophallus is the wonderful aroid Sauromatum venosum (syn. S.
guttatum). This voodoo lily, hardy to zone 5b-10 is equally as bizarre with the same blotched
green and black stem, topped with a giant hand like green leaf. In very early spring, the flowers
emerge 1" wide x 3' tall. Each flower is beautifully patterned yellow and purple. This easy to
grow aroid has an equally as disgusting smell as amorphophallus, but again, only for a day.
When talking about bizarre, I could include nearly every plant in the aroid family, but the
one that couldn't be omitted is Arisarum proboscideum (mouse plant). This bizarre aroid (zone
6-9) emerges with a flower in late winter (early spring in the north) that resembles an upside down
small purple mouse with a white posterior diving into the ground, while its 6" tail waves in the air.
After the bloom fades, the arum like green leaves make a small mat to 6" tall. The foliage dies
down like spring bulb foliage, only to re-emerge the following late winter.
Dasylirions (sotol) are another group of underappreciated strangers. These natives to the
heat and sun of the southwest US and into Mexico should certainly be welcomed where yuccas
are used. I like to refer to dasylirions as "gussied up" yuccas. The most common species D.
wheeleri (zone 7-10) is a yucca like grower with powder blue slightly twisted leaves, eventually
making a 6' wide x 4' tall clump. D. longissimum although less hardy (zone 8-10) is one of the
most spectacular species with rigid long arching stems of pencil thin leaves, radiating from the
slowly developing palm like trunk..
There are a number of other dasylirion species, many of which are a botanist's nightmare
to identify. Dasylirion leiophyllum (zone 8-10 at least) is powdery blue like D. wheeleri, while D.
texanum (zone 7b-10) has green foliage.
While we are discussing natives, one of my favorite groups are the amsonias or blue stars.
For strange, you can't get much better than the vertically challenged Amsonia ciliata v. filifera.
This native to the sandhills regions of central Georgia has very narrow leaves...much finer than A.
hubrechtii and a ground cover like growth habit. With a maximum height of 6" and a spread of 2-
3', this ground cover blue star is perfect for a sunny mound. In spring, the clumps are topped with
the typical clusters of light blue flowers. Since it is fairly new to cultivation, hardiness is unknown
north of zone 7.
Another bizarre native plant selection that amazes all of our visitors is a little erigeron
found by Dick Weaver, founder of WeDu Nurseries. While walking along the railroad tracks near
his home in Marion, NC, Dick spied a crinkled mound of green that he assumed had been a victim
of railroad herbicide. After moving a piece to his nursery, Dick realized that this corrugated gem
was indeed a worthwhile selection of the native Erigeron pulchellus. Realizing that it most closely
resembled a green "cow chip", Dick opted for the name Erigeron 'Meadow Muffin'. This slow
spreader makes 5" wide green muffins to 1" tall. In spring, the clumps are topped with single
stalks of 1" pink daisies to 6-10" tall. If your customers like bizarre and cute in one plant...this is
it!
For a native plant that likes it wet, you can't loose with the white top sedge, (Dichromena
colorata). Looking like a typical sedge until mid summer, the clusters of foliage at the top of the
15" stems suddenly burst forth with spectacularly curious white bracts. This native from coastal
Virginia into Florida is perfect for the bog garden, and can even be used as an aquatic annual in
the frigid north (zone 7-10 at least).
In the new bizarre but incredible, I couldn't omit the Stokesia 'Omega Skyrocket' from
the Atlanta Botanical Garden. Curator Ron Determann was searching for pitcher plants in
Georgia, and came upon a stand (recently bulldozed) that also included this unusual stokes aster
with 3' tall bloom spikes topped with unusually large blue purple flowers. Determann saved seed
of this unusual strain and began distributing the seed and plants thru Saul's Nursery of Georgia.
I guess an article on bizarre plants would be complete without mention of our wonderful
native carnivorous plants. Obviously the most popular carnivorous plant is our native Venus fly
traps, Dionaea muscipula. These strange looking plants...probably left by visitors from outer
space, make a flat rosette of stems that end in an fly trap like appendage. Each appendage opens
to reveal sensitive trigger hairs, which when touched in sequence causes the trap to close on the
unsuspecting prey. These full sun boggy soil lovers will flower when happy with 18" stalks of tiny
white flowers, but trust me...these are grown primarily for the traps.
My favorite of the carnivorous group are the pitcher plants (Sarracenia). Each leaf on a
pitcher plant ends with an opening that quickly fills with water like a drinking pitcher. As insects
get a little too close, they fall in the water and drown. Unlike the venus fly trap, the flowers on
pitcher plants are as bizarre as the pitchers themselves. Most species flower in early spring with
dramatic flowers resembling a smashed pumpkin dangling underneath a miniature umbrella. The
flowers are usually green, yellow, pink, or red.
The most common species of pitcher plants available in the trade are S. leucophylla (zone
6-9) (green pitchers with white tops and red veins), S. purpurea (zone 4-9) (green and red
pitchers that lay flat), S. psittacina (zone 7-9) (green and red pitchers that lay flat with a pitcher
resembling a cobra head), S. elata and S. flava (zone 6-9) (both green pitchers with chartreuse to
yellow tops), and S. minor (zone 6-9) (green pitchers with a white window in the back of the
hooded pitcher). As with Venus Fly Traps, pitcher plants prefer bright sun and boggy soils that
are very nutrient poor.
One of the most stunning members of our weird but wonderful contingent is the coral
bean, Erythrina x bidwilii. This bi-specific hybrid between our native E. herbacea and E. crista-
galli probably occurred during some unprotected sex a few years back. The hybrid has proved to
be the most cold hardy coral bean in our trials (zone 7-10). E. x bidwilii doesn't emerge for us
until late May, when it nearly jumps out of the ground. At the end of every 8' twisting stalk of
trifoliate foliage is a 18" spike of gaudy red lipstick shaped flowers. For us E. x bidwillii flowers
non stop from June thru December when given plenty of baking sun.
For the truly bizarre nurserymen, you must try ephedras. I had my first encounter with
these US and Asian endemics at the Atlanta Botanical Garden several years ago. The foliage of
blue pencil lead size jointed branches most resembles a plate of blue spaghetti...or for you plant
nerds, sort of like a equisetum that has been plugged into an electrical socket (horsetail). There is
a variety of species (40), but the most popular is E. sinica, from which the drug ephedrine (called
Ma Huang) is derived. I wondered why we got so many new customers once we started offering
ephedra. Some species only get 2" tall (E. minima), while others get 5' tall (E. equisetina).
Despite the advantage/drawback of its herbal uses, ephedra makes the perfect groundcover for a
dry sunny site, and is guaranteed to get your customers asking...what the?
Most of the really cool contorted plants are woody plants...the perennial world really got
cheated. Our chief representative, however is the group of juncus (rushes). Despite your political
leanings, corkscrew rush is too cute to ignore. These wonderful evergreens are great additions to
any bog garden.
There are actually three different corkscrew rushes. The most common is Juncus effusus
'Spiralis'. This bizarre rush has glossy green stems that coil outward like a twisted unicorn horn
to 12" long. From the base of each clump, you could have as many as 30-50 spirals heading in all
different directions. This is one of those truly fun plants enjoyed by both kids and adults.
I picked up a dwarf form in England under the name J. effusus 'Curley Wurley', which is
about half the size of the normal corkscrew rush. This dwarf to 6" has even tighter corkscrews
than the normal and seems to retain a fair amount of bounce thru the growing season. The foliage
is the same very thin glossy green of J. effusus 'Spiralis'.
The really bizarre member of the corkscrew rushes is Juncus inflexus 'Afro'. This giant
corkscrew rush reaches nearly 2' in height with wonderful soft blue grey foliage. The foliage is
nearly 5 times as thick as that of the other corkscrew rushes. This is a marvelous plant that I hope
reaches the market one day soon.
If you're bored by the "bread and butter" plants that you have been growing and want to
find a new niche, consider at least adding a little fun to your line up by seeking out some of the
weird and wonderful members of the plant family for your customers.
