Went for a stroll around Lake Głębokie, which is popular as a city bathing spot (the Polar Bear Club was out in force!) The lake is surrounded by mixed forest and includes several Natural Monuments, including this huge Oak (more info in ALT text). #ThickTrunkTuesday

At the foot of a shabby wall on an unprepossessing verge
I think these are leaves of Canadian Goldenrod, Solidago canadensis, so guess the #mildew on them must be Aster Powdery Mildew, Golovinomyces asterum. 🤔

#OnThisDay in 1859, Charles Darwin's On the Origin of Species was first published.
Much of the original manuscript was used as scrap paper by Darwin's children. On the back of this painting of a house is an original manuscript page from Origin!

This roundabout is on my route from the railway station to town centre in Bury. Ragwort grows between the tracks at the station. Not easy to get close but think this may be the reservoir of the plant in the town! Narrow-leaved Ragwort, Senecio inaequidens, #WildflowerHour at #BuryStEdmunds station.

Something a bit warmer for this #FernFriday. Sticheropsis truncata, an upland fern from Indonesia. The fronds appear to fork, but actually extend continuously, with a hidden bud in the fork allowing the plant to spread out seeking light in forest gaps. #BritshFernSociety #BPS #RBGE
