I've heard (on the forums) of Jack-in-the-pulpit but have never seen one. These come from Madagascar and nearby and should grow well where you are. They're easy to grow but do produce a lot of seed. I'm planning (in the not too distant future) to have a larger pond with a lot of them. They do add nicely to the landscape. Walking beside their pond you're walking under their leaves. I intend to set them up so I can paddle my canoe under them.

mine has been struggling in too small a pot for a few years, but it bloomed several times. We just moved it to a 150 gallon stock tank filled with bentonite granules and water, and it's already looking better.

It won't take long for it to take off and get huge. They don't wait for an invitation.

The British Jack in the Pulpit is our native Arum maculatum. The common name Jack in the Pulpit is used in the US, I believe, for Arisaema triphyllum. They and the OP's plant are in the same Araceae family.

The Arums (species) and Arisaemas won't grow here. Wrong climate. But I've seen photos of some very nice ones.

One of Alberto Burle Marx's favorite landscape plants for wet and warm climates. Here,I settle for the similar Alocasia portodora. Not as large as the Typhon.,but can in best cases still get large.
