I am working on a school research project that involves removing lead from plant soil. I was wondering which plants, that are in season in the winter, for zone 6, are known to absorb the most lead from the soil.

My project requires several plants for testing and I would prefer to purchase plants rather than grow them from seeds.

Any help you can offer me would be greatly appreciated.

Thank you!

Sounds like an excellent research project. I'd be interested in learning your results when you have finished your research.
I'd rather weed than dust ... the weeds stay gone longer.

Welcome! Alex. Are you going to be growing the plants in a greenhouse? I'm just wondering what you mean by "in season", do you mean plants that are available for purchase at this time of year?

This article on lead toxicity in plants may give you some ideas:

Also if you Google with the keywords: lead phytoremediation you will get lots of results. Also try Google Scholar:

If you can make a list of suitable plants by looking at these research papers then we can most likely give you an idea whether they are obtainable.

Good luck with your interesting research.

Thank you both for responding.
The only reason I want to use "in season" plants is that they would be readily available at my local garden shop for me to purchase.
I am currently growing Mustard Greens derived from seeds and they are taking a long time to grow large enough. So, I thought I would find out what other plants have a high lead absorbency and purchase them.
I will report back after my lab time with the Mass Spectrometer.
Thank you!

zone 6 just isn't going to grow much over winter, outside, it's too cold. Mustard greens were an excellent choice. The other thing growing well in my yard right now (zone7) are winter weeds like Lamium purpureum and Cardamine hirsuta
If inside under lights, then there are more options. I still think mustard greens would grow well indoors under lights. You can't really do corn or any other big field crop.
