The Park is located on the North Bank of the Thames: just Upstream from the Thames Barrier viz.
We hoped to find a few Hoverflies and some Wild Flowers: and were successful, up to a point.
The Park itself is regularly mown: nevertheless, we managed to find quite a few Wild Flowers both in the Park (which includes a couple of small 'Wild Areas', where we found
Common Mallow,
Common Ragwort,
Creeping Thistle,
Goat's-Rue,
Mugwort,
Wild Carrot,
Yarrow &c.) and the Surrounding area.
Sadly though: with lots of new Residential Developments, the area generally qualifies for the Description, Concrete Jungle! Not a place we will probably ever return to. And we found the 'Sunken Garden' disappointing.
