Propagating - Arisaema triphyllum 

The above slide show gives you an idea of the progress a Jack-in-the-Pulpit makes in a four week time frame.

The instructions for propagating Jack in the Pulpit said... 60 days cold, moist storage followed by 60 days of warms moist storage then back in the refrigerator for 2 more months. My Jacks couldn't wait for spring  and sprouted after their first round in the refrigerator.

- Spring is just around the corner. Our Jack-in-the Pulpit plants are now 7 weeks old. They will stay just about this size during the entire 2011 growing season.

Raising wildflowers takes a great deal of patience, these Jack - in - the pulpits will not be marketable until the spring of 2012. Luckily most of our plants don't mature this slowly.

Wildlife Significance - Jack-in-the Pulpit

Pollination - By Fungus gnats. I wasn't exactly sure what a Fungus gnat was - this is  what the University of California Agriculture on line site had to say.

" Although larvae of these species may feed on plant roots outdoors, none causes serious damage outside the home. Any root feeding by these species in gardens or landscapes is usually minor in comparison with their beneficial role as decomposers in helping to convert dead vegetation into nutrients for plant growth."
