I have swamp weed seeds available if anyone would like them. The first 3 pods just opened this week, with several more to come. This is the white-flowered plant. I bought it last year from a local nursery and it didn't bloom last summer. This year it has been my best performer. The carpenter and honey bees love it! It is also where I collected the 2 eggs earlier this year. I think if you plant the seeds now, you will have gorgeous plants next spring. Send me a PM if you would like me to share.
