 Jack in the Pulpit Info

The scientific name of jack in the pulpit is Arisaema triphyllum. After the jack in the pulpit plant flowers has been pollinated by insects crawling into the spathe or hood of the plant, the spathe withers and a small cluster of green berries will appear. The berries will continue to grow and change hue from green to orange by August and then to a brilliant red by September. This fire engine red is actually the signal to harvest the berries for propagation. Once you have gotten the berries, just locate the jack in the pulpit seeds which are inside the berry. There should be 1 to 5 white seeds inside. Just roll the berries around with your gloved hand until the seeds are visible. Remove the seeds from the berry.  

At this moment, you would think that planting the jack in the pulpit seeds is all that needs doing but propagating the plant from seed depends on a period of stratification first. You can either deposit the jack in the pulpit seeds in the soil outside, water in well, and then let nature take its course or stratify the seeds indoors for later propagation. To stratify the jack in the pulpit seeds, just place them in moist sphagnum peat moss or sand and then store them in the refrigerator in a plastic bag or storage container for about 2 and a half months.
