In the springtime it smells of rotting flesh and as such
exhibits what I’ve termed carrion
mimicry. The potent putrefying smell
draws hundreds of flies to the plant and those become the preliminary
pollinators. Known commonly as Junco (Hoon-Kowh) this mass of green thorns
goes through several pulse blooms throughout the summer. Subsequent blooms are not as strong smelling
as the first which more-than-likely is a selective mechanism designed to
diversify the pollinators. Summer blooms
of Koeberlinia spinosa have a sweeter
smell than the horrific stink of the first couple of blooms in late spring and
moths and bees become the main pollinators in later blooming periods. The flowers are small and white. The plant has no leaves to speak of other
than small residual nubs that are, in effect, leaves. However, the ultra-green stems (including the
long thorns) are the site of photosynthesis within the plant.
The smell of early blooms is almost exactly the same as
putricene or Tetramethylenediamine, NH2(CH2)4NH2. That’s the smell of a rotting animal. It’s not uncommon to wander into the
brushlands looking for a dead cow or deer only to find out you’ve been tracking
the scent of flowering Junco.
Junco has been used to make traps for rodents and small
game. When dried it is highly
combustible and therefore makes excellent kindling. The wood (if you can get past the thorns) is
sometimes used for knife handles and small figurines. People have planted junco around corrals and
even their jacales (small mud and
stick huts) in order to keep large predators at bay. I imagine they take extra care to plant K. spinosa downwind.
Junco is one of my favorite Brushland plants because 30 years
ago I spent a considerable amount of time studying its ecological role in the
region. I’ve used the thorns to make
rodent traps but not much more. I simply
enjoy looking at Koeberlina spinosa
and have sort of an affinity for the plant.
After all, it’s the Brushlands Green Madness.
