The only problem is hat most G.violacea forms are annual in the
wild and thus are probably adapted to germinating after a dry period. Yet
G.aurea (which was the one I had mentioned about a specific population
which dried out and no plants there the next season) is perennial and it
appears that it doesn't even flower every year in many populations.
Considering also how big it is, I imagine it takes several years to attain
maturity, or at least attain the 5cm rosettes which used to be present at
that specific site. So hopefully there were seeds around to germinate in
that population, or else it'll take even longer for seeds from another
site to find their way there and start again.
As to G.uncinata, I have just heard a report from someone who
obtained Genlisea seeds from my friend Fabio last year. He says the
G.uncinata seedlings (only 2 or 3) are growing very slowly, while
numerous G.violacea seeds germinated and are growing very fast, and
G.aurea never did germinate. I would like to hear from other people who
have tried germinating Genlisea seeds, specially in regards to G.uncinata
and G.aurea. Has anyone been successful? What about the in-vitro workers?
Any luck with G.uncinata Andreas??
Best Wishes,
