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 online 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."
Deer - Do not enjoy this plant
Leaves and Berries - Popular with Wild Turkeys and the Wood Thrush. Since our nursery is in as suburban neighborhood, this is hearsay and not first-hand knowledge

Propagation Notes Arisaema triphyllum

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. February 21, 2011 - 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.
