The Yellow flowering Lesser Celandine (Ranunculus ficaria) is in my opinion a common plant of urban areas, along with many hedgerows & roadside banks. In Kessingland south of Lowestoft (UK) it grows in almost all gardens, even in cracks in the pavement Stace lists four subspecies but I have only recorded R. ficaria ficaria & R. bulbilifer. Bulbilifer has tubers forming in the leaf axils which can only be determined after flowering. Those to look out for are the plants that grow close to habitation & in the shade.
This is another plant that spreads rapidly if planted in your flower borders.
Also in Kessingland I saw a small garden pond with the weed Azolla (Azolla filiculoides) it is a water fern that chokes still waters. It is red in colour & can cover a bucket of water overnight. It is an uncommon fern of dykes along the Suffolk coast & can only be killed off by hard frosts. Many blame those who release frogspawn into the dykes along with their own pondweed, thus spreading this red weed further.
