Collecting fully-ripe seeds is difficult. The county mows road
shoulders at irregular intervals, making the plants hard to find
at all and scattering what seeds might be present.

I've tried grabbing a few whole plants at random times, hoping to
find a few mature pods, but it seems that if visible flowers are
present essentially no pods are filled out. Once bloom ceases the
plants are surprisingly hard to find among the other weeds.

Is there any technique to help unripe pods mature enough to yield
viable seeds, either left attached to the plant stem or taken
off? Might putting the cut stems, with pods, in water like cut
flowers allow any useful development?

Thanks for reading,

If you pick them before they are ready, seeds will not mature. You
might try digging up a plant and potting it to keep it alive until its
seeds mature naturally.

Granted, if I pick just the pod too early there's no hope. I was wondering
if taking a substantial cutting and keeping it hydrated to some extent
might promote at least partial maturation.

Plantnapping isn't exactly a crime, but it's more work and getting late
in the season...

That might work with a perennial or woody plant. It almost never works
with annuals. The only annual I ever saw as an exception was a
marigold. One summer, I grew some tall merigolds and made a bouquet of
them for my wife. After a week, I went to change the water in the vase
and discovered the stems had put out roots into the water. The bouquet
lasted several weeks.

Well, that proves it's possible. I'll grab a bunch and try to keep
it moist on the way home, then stick the stems in water. I don't
really expect roots, a little more development of the pods would be
helpful. If not, it was cheap entertainment...

I've collected a few bunches of vetch with both pods and flowers.
Some pods have been detached, to dry separately. Some whole bunches
are drying intact, so see if it makes a difference. Another bunch
or two have been placed with stems in water, to see if keeping them
a little hydrated helps any.

One thing I haven't seen are any obviously ripe pods, even from the
bottom of apparently-old plants. All pods are bright green, much
like snow peas. Pods at the bottom of the plants have obvious seeds,
but none are filled to the extent seen with snow peas, which fill
the pod to near-bursting when close to ripe.

What does a ripe common vetch pod look like? Links to photos would
be ideal, photos found so far are mostly of flowers and leaves.

That is a most impressive site.

The only ripe pod image I could
find was
https://www.gbif.org/occurrence/3044680742
which is from New Zealand. If that's what mine need to look like
I'm nowhere close to having ripe pods.

Everything I have looks like a miniature snow pea with visible seeds.
This picture is close:
