Yes I have started down this road but it is very early days yet. This
year is my first serious attempt at crossing the various Dionaea clones
which I have collected over the previous few years. The largest clone I
have so far has traps in excess of an inch and three quarters and
particularly long petioles giving. Potentially this plant can reach
eighteen inches from trap to opposite trap - quite a monster. I say
potentially as the neccesity of allowing the plant to set seed reduces
trap growth and production. This clone has been unofficially names as
South West Giant - a reference to a Carnivorous Plant nursery here in
the UK rather than any reference to the South Western USA. I know that
it cannot be named as a cultivar without first being published and AFAIK
a text is in preparation.

It is certainly something I have observed and it would appear to be
genetic rather than environmental although AFAIK no work has been
carried out to establish this as a fact. I have also observed clones
which consistently produce the long spindly petioled traps all year
round.
