  In this contribution an entirely different way compared to conventional
approaches for axion, hidden photon and dark matter (DM) detection is proposed
for discussion. The idea is to use living plants which are known to be very
sensitive to all kind of environmental parameters, as detectors. A possible
observable in such living plants could be the natural bio-photon level, a kind
of metabolism related chemoluminescence. Another observable might be
morphological changes or systematic leave movements. However a big problem for
such kind of experiment would be the availability of a known, controllable and
calibrated DM source. The objective of this small paper is primarily to trigger
a debate and not so much to present a well-defined and clearly structured
proposal.
