While walking with my dog, I saw something gleaming red in the sunlight. I walked out to see what it was. It reminds me of an Arum but surely not in the southern wilds. Any thoughts.

The leaves really do make me think of Jack-in-the-pulpit, which is an arum of course.

You may be right.
Wildflowers of the Big Thicket list three different types. I wish I had seen the bloom.

That is Green Dragon - Arisaema dracontium - a North American native
The bloom is similar to Jack-in-the pulpit but with a very long tail.
Greendragon (Arisaema dracontium)

Thank you for that ID.

For my education, there are three listed for this area.
A. dracontium
A. triphyllum
A. quantum (noted as uncommon in this area)
What was the identifier that made you comfortable with it being the first one?

Those are berries. You can harvest them and grow those from the seeds they have inside the berries

When I saw the leaves, I immediately thought Arisaema dracontium also.

What was the indicator for your immediate ID? Still attempting to educate myself.

I think I will leave them for the birds to share. I am sure that is how it arrived at my place.

Some reading I have done indicates calcium oxalate crystals can be found in parts of this plant. As I live with pets I'm going to pass on propagation.

I do hope to see blooms on this plant next year though.

I appreciate everyone for their IDs.

I still hope to learn how to determine which one it was.

Meanwhile I will mark it finished with thanks.

Have you compared the leaves of the 3 different plant? They're each quite distinct.

Uh... I doubt that you need to be concerned about animals eating any part of this plant...
Those oxalates have a very 'sharp' taste... not a desirable thing to have in your mouth.
Although...
Here's somebody that suggests edible uses for this group of natives...

I'm not going to try it...

All aroids have oxalate crystals. Taro leaves (Colocasia escuelenta) are widely eaten in SE Asia and India. They have to be cooked, which I guess renders the oxalate harmless. Can't be eaten raw

I am not familiar with A. quantum? (quinatum?). However, I grow A. dracontium and A. triphylum in my garden.
Their leaves clearly differ from each other.

A. triphylum is Jack-in-the pulpit.
The "triphylum" part in its name describes the three lobes of its leaves.



Whereas A. dracontium 's leaves are shaped in a swirl as shown in the OP's photo above.

Thank you very much for the description, complete with photos. I was thinking I may need to wait till it bloomed next year to clarify the ID in my mind. Your assistance is appreciated.

Jack in the Pulpit or Green Dragon. See Google Lens for added details
