:) Here are a couple more I've seen in the Knotweed family. Both of these were at #PtReyes. The first is a macro of Beach Knotweed (Polygonum paronychia), and the 2nd is Water Knotweed (Persicaria amphibia). 💚

Par beach for Sea Daffodils Pancratium maritimum, which disappointingly were in bud and fruit but not flower.. Sea Knotgrass Polygonum maritimum (in huge amounts) saved the day though #wildflowerhour

There seems to be huge amounts of Common Knotgrass, Polygonum aviculare, in the streets of Brighton. Never seen it so abundant; maybe rain after drought has trigged abundance? #urbanbotany #streetbotany @bsbibotany.bsky.social

I had to look up polygonum; apparently it includes knotweed and knotgrass.

Miss Marple calls it "one of the quickest flowering shrubs which swallows and kills and dries up and gets rid of
everything it grows over. It grows over everything. It is in a
way a rather frightening plant."

Bonus #flavoradded: Buried in the Garden

"Verity’s here still, isn’t she? She’s here in the garden. And then the polygonum was planted there and has flowered ever since, growing bigger and stronger every year. Verity has remained here with you. You never let her go."
- Jane Marple, "Nemesis"

House sparrows were gathered because their favourite fruit is in season just below this fence: the seed pods of Polygonum aviculare, common knotgrass, a prevalent weed of municipal lawns.

#nativeplants For #bikepacking 🚴🏼‍♂️ peace of mind, this IS NOT Puncturevine aka Biker’s Bane / Goatshead; it’s the harmless & potential healing native, Common Knotweed (Polygonum aviculare)

I know what this is. It's Japanese knotweed. Incredibly invasive. It will regrow from a tiny smidgen of root. I've all but eradicated it by hitting it with a blow torch after rain, as it'll heat the roots via water and steam them to death. www.ontarioinvasiveplants.ca/invasive-pla...
