Arisaema dracontium, or green dragon, is what I call a "twofer." It blooms in April, then the second half of the twofer begins in September as its seeds ripen, turning waxy, fiery-red.
Arisaema dracontium (which is native to most of eastern North America and the US Midwest) is a late riser. It does not emerge until well after jack-in-the-pulpit (A. triphyllum). In my Indiana garden, that is around the very last of April with warmer winters and the springs we've been having recently. Sometimes it's the first part of May.
Unusual growth habit
When emerging the green dragon resembles an umbrella. Completely formed in all parts, the bloom or inflorescence pushes up first with the foliage unfolding along each side. The “bloom” matures, with foliage forming over it.
The size of the plant can vary greatly, due to genetics, environment, and cultural practices in the garden. Generally the height is from about 15 inches up to 30 inches.
The tall, stout stalk coming up from a shallow tuber has no foliage except at the top. Then there are 5 to 15 leaflets formed around the outside edge of a half circle that some liken to a horseshoe. The half circle sits centered upon the stalk.
When mature, green dragon will "bloom" about one-third to one-half of the way up the stalk from the tuber. On a slender stem, a fleshy tubular-shaped inflorescence forms with a long pointed “tongue” reaching upward alongside the stalk.
This modified leaf can be up to two inches or more in length with the tongue reaching up to six inches or more. I have seen the various colorations of the tongue ranging from the same green as the rest of the plant to orangey-yellow.
