<abstract>
<para>I became enchanted with Jewelweed (also known as “touch-me-not”)
before I was in the first grade. Then we moved away from New England
and I didn’t see it again for the better part of two decades. By the
time I encountered it again, it was a hazy childhood memory.</para>

<para xml:id="p2">I became enchanted with Jewelweed (also known as “touch-me-not”
for reasons that will become clear momentarily) before I was in the
first grade. Then we moved away from New England and I didn’t see it
again for the better part of two decades. By the time I encountered it
again, it was a hazy childhood memory.</para>

<para xml:id="p3">Jewelweed, a member of the <emphasis>Impatiens</emphasis>
family, is a small, bushy plant that likes wet soil. The nearby patch
grows right along a little creek. When in bloom, it displays a
profusion of small orange flowers.</para>

<para xml:id="p4">A little googling this morning reveals
that they’re much liked by hummingbirds, so I’ll be scattering some
seeds this fall in an attempt to bring Jewelweed into the garden. I
fear the flower beds won’t be moist enough, but I’ll try. Scattering
the seeds is going to be really easy.</para>

<para xml:id="p5">The quality of Jewelweed that seemed magical to me at age 5 or so,
and still tickles me quite a bit, is its mechanism of seed distribution.
Ripe Jewelweed seed pods are exceptionally fragile. The slightest touch
causes them to “explode,” scattering seeds over a space of several feet at
least.</para>

<para xml:id="p6">If you trap one of the seed pods in your fingertips (no easy feat if
the pod is really ripe, which the one below was not) and release it slowly,
you can watch the pod unzip itself and collapse into a little ball.</para>

<gal:image rdf:resource="images/20040826-195517"/>

<para xml:id="p7">Put the slightest pressure on the pod</para>

<gal:image rdf:resource="images/20040826-195536"/>

<para xml:id="p8">and it unzips down one or more “seams.”</para>

<gal:image rdf:resource="images/20040826-195557"/>

<para xml:id="p9">Then the pod begins to curl</para>

<gal:image rdf:resource="images/20040826-195609"/>

<para xml:id="p10">and twist</para>

<gal:image rdf:resource="images/20040826-195619"/>

<para xml:id="p11">and flings the seeds a considerable distance.</para>

<gal:image rdf:resource="images/20040826-195640"/>

<para xml:id="p12">Unrestrained, the whole process takes a small fraction of a second.
The little black seed is from a riper pod that exploded before I could even
get my fingers around it.</para>

<para xml:id="p13">I can’t quite imagine what biological process produces the tension
in the seed pod, but it sure works.</para>
