Flowers are only important for sexual reproduction and sexual reproduction is
the only way in which genetic variation and hence evolution can occur at the
rate it does.
Also, as far as I know no-one has ever changed suggested that seed result from
asexual reproduction.

Are we talking about Lamark or Darwin. Under Darwinian theory plants do not
adapt but are selected by virtue of environmental pressures it is a passive
process. The less constant the environment the more likely variation is to
occur.
Keep up the good work
