[Thread] So, let's talk about #Knotweed! Yeah, it's extremely invasive and hard to get rid of. And you DON'T want it anywhere near your buildings, especially basements (and yes, my grandparent's backyard was overtaken by it -- luckily, it preferred the backyard being near a marshy area). I spent a lot of time as a child practicing swordfighting with a wooden sword, and cutting down the knotweed. I sometimes wondered if it was edible as well (since it reminded me of rhubarb -- and yes, it is edible). And of course, the BEES love it. But still...

Anyhow, let's examine natural solutions to getting rid of knotweed, and if it's somewhat contained and not a threat to structures, it can be used for food and building materials...

Genetic Polymorphism of Invasive Species of Knotweed (Reynoutria) Assessed by the matK and rpl32-trnL (UAG) Regions of Chloroplast DNA - Cytology and Genetics

Abstract An important model system for studying the role of genetic diversity and hybridization in plant invasions is the species complex of the genus Reynoutria Houtt. Within the secondary distribution range, two species of this genus are widespread, R. japonica Houtt. and R. sachalinensis (F. Schmidt) Nakai, as well as their derivatives, the hexaploid R. × bohemica Chrtek & Chrtková and the tetraploid R. × moravica (Hodálová and Mereďa) Olshanskyi and Antonenko, which are recognized as separate species. The genetic diversity of the species of the genus Reynoutria in Ukraine is still almost unexplored by molecular methods. In this work, we determined chloroplast haplotypes for samples of R. japonica, R. sachalinensis and R. × bohemica from Ukraine and other European countries and compared them with haplotypes of Reynoutria from the primary distribution range in China and Korea. The genetic diversity of R. japonica from the primary distribution range was significantly higher compared to European samples, which are mainly represented by the haplotype J1.1. At the same time, we identified haplotypes J1.2 and J1.3 specific to the Eastern European area, which probably arose as a consequence of the divergence of the chloroplast genome within the secondary distribution range. Of the five samples morphologically identified as R. × bohemica, three carry the haplotype J1.1, which is consistent with the idea that R. japonica var. japonica was involved as a maternal form in the formation of R. × bohemica. However, a chloroplast haplotype identical to R. sachalinensis was detected in two samples from the Alpine region of Europe. These samples likely represent another hybrid species of R. × moravica. Therefore, the use of chloroplast DNA markers is crucial for identifying the donor of maternal subgenomes in hybrid forms of the genus Reynoutria.

I grow #ThaiMint & #VietnameseCoriander out of one of two repurposed bathtubs that I use for #gardening purposes.
Vietnamese coriander isn't a true coriander. It's actually an #edible #knotweed. Never put these into the ground if you don't want it to spread. I grow all of ours in containers. I have 2 large grow bags with lots of them growing. I grow lots of both of these plants because we use them in/with our Asian foods often.

I recently found out I have a small infestation of European Knotweed in a corner of my yard, and this is Bad. Sounds like somewhere between having Tribbles and Triffids. Fortunately, the country has an eradication program to protect watersheds, and I qualify for a free cleanup, but I forgot to send in the permission form for them to come on my land. Had to run it to the county seat today. Also, getting rid of this may take THREE YEARS!

So, if flooring products and furniture can be made from #Bamboo, it can be made from #Knotweed. TBH, the best way to deal with an invasive species is to find a use for it (and/or eat it into near extinction -- humans are good at that...)

Japanese knotweed's potential for #furniture

"For designer Samy Rio, a cabinetmaker by training, a change of perspective is needed when it comes to how Invasive Alien Species are dealt with: 'Current destruction policies of IAS—be they floating primrose willow, bamboo, baccharis or Pampas grass—are not a solution. These invasives should be considered as potential sources of raw materials—a resource to be valorized, in particular to create new materials with added sustainable value'.

"The Gardon table—thus named for the river in the south of France where the plants were harvested—features a top made from Japanese knotweed honeycomb and legs from solid Robinia laminate assembled with pre-vulcanized latex glue. Or the 3KG bench: a two-meter bench that weighs three kilos made from panels of Japanese knotweed sandwiched between 3 plies of black locust veneer."

Japanese Knotweed: an invasive plant's potential for innovation

Classified as an Invasive Alien Species (IAS), Japanese knotweed is renowned for undermining ecosystems. But some researchers, designers and...-materials
