After reading The Australian Geographic issue 149, Mar/Apr 2019, we are surprised your website is giving tips on how to grow Dutchman’s Pipe Vine when the Australian National University is telling us this plant is a non native and an invasive species. It’s toxic leaves are threatening the existence of some butterflies in QLD and North Eastern NSW. Could you comment on this please.
Thank you for this information and I have passed it on to our Editors. It takes a village and we love sharing information with gardeners around the world!
It is over 70 years old. It shades the porch. Never had a problem.
Wow! A 70-year-old plant is fantastic! I doubt the increased rainfall harmed the pipevine because they like moisture. However, they also like well-drained soil. You don't say it's failing, just not growing. Even though native plants don't require much, if any, fertilization, after 70 years, that site could be depleted. Have you considered a soil test to check the nutrients in the soil? Your local extension service can help with one. Also try pruning the vine to encourage new growth. Here are basic facts:

and dried up completely. Is the plant dead? This happened in July.
It is just likely injured from the heat. If you prune lightly, and take off any fully dead growth, it will likely recover. Just care for it as usual until it recovers.

Ours was eaten completely off by swallowtail caterpillars and the vines are now very woody and dry. We have cut it back to the soil. Will new growth appear. We are in South Florida, so is it too hot right now?
This is a perennial. It attracts the butterflies by nature. They are considered beneficial since they are pollinators. This article will help you with the care of these plants: https://www.gardeningknowhow.com/ornamental/vines/dutchmans-pipe/growing-dutchmans-pipe-vine.htm
Luckily, they should come back. I never pruned mine and the next spring the leaves just filled in on the vine. However I am in zone 6 and you are in hardiness zone 10. The article below gives specific prunng information.

I live in Florida and I am seeing on your site that you can grow this from the seeds. I have a huge plant that I have had for many years. I just can't figure out where the seeds are. Are they located in the green part of the plant below the flower? After mine flower this part falls off with the flower. I have never seen a separate pod that is shown on websites. Any help would be appreciated. I want to start one of these for my aunt for her 90th birthday this year. If another method of starting one is better please advise. I love your website and have learned so much here!
There is, actually, a much more reliable method for reproducing this plant! You can take a tip cutting when the plant is not flowering, or you can pull flowers off of that stem for a cutting. This will grow a plant that is a complete replicate of the original.

P.S. I had a Dutchman's pipevine for years and never saw the pods either.
I have plants with very similar leaves but can't find the name of the plant so can't plant them in the ground in right place. Please see the attached photos... marked 1 and 2 to name. Thanks. Philip.
They look like Aristolochia. This article will help:

Thank you for responding.
The person who sent these plants to me forgot the names. She said one is Dutchman's Pipe but she is not sure which one. Both are not Dutchman's pipe.
I want to start some california pipevine seeds and need to know how hot the water should be for soaking them 48hrs
Our experts say very, very warm water - not boiling - for around 24 hours, but no longer than 48 hours. Here's a helpful article:
