a few years ago I had a green dragon "show up" from no where. I didn't know what it was but called my friend the plant lady who told me all about it. For a couple of years it kept coming back but just by itself. (and is back this year), . My hillside was ripe with brush honeysuckle and I have cleard it out over the last 2 years. Now I have several green dragon clumps in the shade of the hillside dogwoods and sassafras trees. This is the first year for them I am marking them with survey stakes to avoid mowing them down. Can these be transplanted?

If you're finding A. dracontium in dry locations, make sure it is not a Pinellia (one of which is invasive). See pics at the link below. http://www.aroid.org/genera/arisaema/herold/Pages/pinflower....

Green Dragon grows on our farm in Dickson County, TN out in the sun on pipeline rights-of-way on dry uplands. So, I am not so sure that it is exclusively the woodland plant that it is usually described as. I have read somewhere, perhaps in Dave's Garden, that the seeds are spread by box turtles who like to eat them. I saw two box turtles by Green Dragons last Fall, though I saw no evidence that they were eating the seeds.

Here in Ames, Iowa, I grow Green Dragons in poor soil in a sunny, hot site that I seldom get around to watering, and they are thriving. They stay looking fresh until long after my jack-in-the-pulpits have gone dormant, and everybody who sees them finds them attractive. It took several years for that first plant to form a nice colony, but it was worth the wait. I have no idea why this plant is doing so well under conditions that are supposed to be harmful to a woodland plant.

A modest cluster of Green Dragon has established itself at the brushy bottom of the hill below our house. At least one corm is mature enough to bear a flower along with the usual leaf. Its development is a welcome feature to the very slowly developing shade garden I am installing on the hillside. Like the more usual Hostas, it does not seem to be troubled by the jugulone released by the neighboring Black Walnut trees.

The plant name, translated, means: Arisaema: Greek aris, a kind of arum, and haema for "blood" - dracontium: Latin for "of the dragons" probably for the deeply divided leaves resembling a dragon's claw.

A beautiful, usually small, native plant, that grows in rich, often wet woodlands, Zones 8-9b. Requires moist soil, high in organic matter, and prefers a sheltered location, especially from wind, with dappled light in the spring, and shade in the summer. Has "dazzling, bright red berries" in the fall. This info is from "A Gardner's Guide to Florida's Native Plants," by Rufino Osorio, published by the University Press of Florida in Gainesville.

Very similar to Jack-in-the pulpit, except green dragon usually has only one large, long-petioled, compound leaf that is divided into 7-15 lance-shaped leaflets and has a greenish spadix which is narrower and tapers up and beyond the less prominent, greenish hood (lacks the distinctive purple striping of Jack) of the spathe. Also like Jack-in-the-Pulpit, this plant goes dormant in the summer, with the mature plants producing red berries which become visible in mid to late summer as the spadix withers. Roots contain calcium oxalate (same chemical as in Diffenbachia or dumb cane) and are poisonous in an uncooked state.
