Eva Ekeblad, 2002

Where they dumped a pile of flower pot soil (full of Leca pellets) in the second week of March (picture below) there is now ONE Pot Marigold, much mown. They keep the nettles short: lawn is being made.

At the old wheel ruts in the Scrap Meadow the grass is crowding out the sedges - the Bur-marigold there was tiny even last year. Now invisible. Today's, much larger, sample is from the construction site side of the Next Block - in a goosefoot-paradise -type patch.
