A corm, composed of dense stem tissue and wrapped in papery leaf bases, is the underground storage structure of some plants. This is the corm of Arisaema atrorubens (Woodland Jack-in-the-pulpit) as it appeared to me after the fruit had ripened.
All parts of Jack-in-the-pulpit contain calcium oxalate crystals. If ingested raw, these crystals are capable of mechanically injuring your mouth, throat and kidneys. To safely eat the corm, as flour or like chips, it must be dried thoroughly or sufficiently cooked.
As a medicinal herb, the raw corm can be pounded into a poultice. This irritating, yet healing poultice can then be applied to rheumatic joints.
I have enjoyed the process of working with Faber-Castell polychromos colored pencils on Stillman & Birn Zeta paper. This strong paper is great for saturation and fine detail. It cleans up well, withstanding erasure with no visible compromise. Offering series of papers within sketchbooks, along with matching sheet papers, Stillman & Birn gives artists a consistency throughout the process of working toward a finished piece. Given my experience so far with this paper, it is a definite consideration for my "Art of the Plant" Exhibition entry!
Below is a scanned digital copy of the finished fruit, mature Jack-in-the-pulpit, species Arisaema atrorubens. Unfortunately, my scanner doesn't pick up the orange reds, nor the deeper colours I used in the shadow areas, so this image does lack the innate depth of the original. Note: variations of the floral parts can be found here.
The "Art of the Plant" Exhibition will be Canada's contribution to the larger exhibition, "Botanical Art Worldwide". "Art of the Plant" will open in Ottawa May 10, 2018, followed by the official "Worldwide Day of Botanical Art" on May 18, 2018. Exhibitions will remain open for several months.
